This video is intended to help students who are trying to get a handle on the complex three-dimensional changes that occur during early development. Drawing, plastic and a sleeping bag will hopefully clear up some of the challenging concepts in early development.
This is Part 1 of Professor Fink's Human Embryology Lecture. The Lecture distinguishes between sexual reproduction & sexual intercourse and describes In Vitro Fertilization. The Lecture then compares & contrasts Spermatogenesis with Oogenesis. The Lecture then begins a description of Human Embryology, including fertilization, the development of the Zygote into a Blastocyst & implantation during the 1st Week, formation of the Placenta & the Embryonic Disk during the 2nd Week. The Lecture also reviews the development of the Chorionic Sac, the Amniotic Sac, the Yolk Sac & the Allantoic Sac and discusses Chorionic Villus Sampling (CVS). An introduction to the 3rd Week of Embryonic Development is given. Other Terms presented include: Chorion Frondosum, Decidua Basalis of the Endometrium, Ectoderm, Mesoderm & Endoderm.

Embryonic folding is the process of converting the embryo from a flat disc, into a cylinder.
This cylinder consists of three main layers, derived from the trilaminar embryonic disc: the endoderm in the center, the ectoderm on the outside, and the mesoderm, which is found between the two layers.
During the fourth week of development, folding of the embryo occurs as a result of the differential rates of growth of the embryonic structures. The embryonic disc and amnion grow rapidly, however, growth of the yolk sac is much slower.
Embryonic folding occurs in two planes: the horizontal plane, which results in the development of two lateral body folds, and the median sagittal plane, which causes the longitudinal cranial (head fold) and the caudal (tail fold) of the embryo to develop.
As folding continues simultaneously in both planes, the result is a very rapid development of the embryo.
The endoderm of the trilaminar disc is mainly responsible for the formation of the epithelial lining and glands of the gastrointestinal tract. As the lateral, cranial and caudal folds of the endoderm fold towards the midline, they fuse, incorporating the dorsal part of the yolk sac to create the primitive gut tube.
The gut tube is divided into three main parts: the foregut, midgut, and hindgut.
The foregut can be seen at the cranial end of the embryo and is temporarily closed by a membrane, called the oropharyngeal membrane. At the end of the fourth week of development, the oropharyngeal membrane ruptures to connect the future oral cavity with the pharynx.
Until the fifth week of development, the midgut is connected to the yolk sac, which narrows into a stalk known as the vitelline duct, as embryonic folding continues. Eventually, the yolk sac constricts and detaches from the midgut, and the midgut seals.
The caudal end of the hindgut is also temporarily closed by a membrane, called the cloacal membrane, which separates the upper and lower parts of the anal canal.
The cloacal membrane ruptures during the seventh week of development to form the urogenital and anal openings.
The ectoderm covers the entire outer surface of the developing embryo, except for the eventual umbilical region.
This germ layer, along with the dermatomes, lateral plate mesoderm, and neural crest cells formed during neurulation, eventually form the skin, as well as several other vital structures, including the central and peripheral nervous systems.
The mesoderm germ layers organize into somites, which eventually give rise to muscle tissue, cartilage, bone, and subcutaneous tissue of the skin.
As a result of embryonic folding, the major body plan becomes established, and the three germ layers continue to differentiate, giving rise to their own tissues and organ systems.

By the end of the second week of development, the bilaminar embryonic disc, consisting of the hypoblast and epiblast, has formed.
Throughout the third week of development, this bilaminar disc differentiates to establish three primary germ layers, in a process known as gastrulation.
Approximately 15 days after fertilization, a thickened structure forms along the midline in the epiblast, near the caudal end of the bilaminar embryonic disc. This is called the primitive streak.
At this stage, the formation of the primitive streak defines the major body axes of the embryo, including the cranial end (towards the head) and caudal end (towards the tail) as well as the left and right sides of the embryo.
At the cranial end of the embryonic disc, the primitive streak expands to create a primitive node, which contains a circular depression, known as a primitive pit. The primitive pit is continuous with a groove, known as the primitive groove, which runs caudally along the midline of the primitive streak.
Once the primitive groove has formed, cells of the epiblast migrate inwards towards the streak, detach from the epiblast, and slip beneath into the interior of the embryonic disc. This process is known as invagination.
The first cells to invaginate through the primitive groove invade the hypoblast, and displace its cells. The hypoblast cells are eventually completely replaced by a new cell layer, which is referred to as the definitive endoderm.
By day 16, the majority of the hypoblast has been replaced. Some of the invaginated epiblast cells remain in the space between the epiblast and newly formed definitive endoderm.
These cells form a germ layer known as the mesoderm, which subsequently forms the notochord, the basis for the axial skeleton.
Once the formation of the definitive endoderm and mesoderm is complete, epiblast cells no longer migrate towards the primitive streak.
At this point, the remaining cells of the epiblast are referred to as the ectoderm, and form the third germ layer.
The ectoderm forms from the cranial to the caudal end of the embryo, such that by the end of the third week, the three primary germ layers complete the embryonic disc.
The gastrulation process is finally complete.

This video goes in to the pharyngeal arches, an odd group of folds that contribute a variety of structures to the face and neck. We discuss the arches and their muscular, bony, and nervous features. We then talk about the grooves (outside) and pouches (inside) that create the ears and various glands. I hope you find it helpful!

Implantation of the blastocyst usually occurs 6-8 days after fertilization.
By day 8, the blastocyst has burrowed into the uterine wall, being completely embedded by day 9.
Day 8
The blastocyst is composed of two main components: the outer cell mass, the trophoblast; and the inner cell mass, the embryoblast.
As the trophoblast makes contact with the endometrium, it differentiates into two layers: an inner, cytotrophoblast; and an outer, syncytiotrophoblast.
The embryoblast differentiates into a bilaminar embryonic disc composed of two cell layers, the hypoblast, and the epiblast. Soon after the embryonic disc has formed, a cavity begins to appear between the epiblast and cytotrophoblast, known as the amniotic cavity.
Cells originating from the hypoblast begin to migrate, forming a thin membrane, which lines the inner surface of the cytotrophoblast. This is called the exocoelomic membrane. The exocoelomic membrane and cells of the hypoblast together form the walls of the primitive yolk sac.
Day 9
Once the blastocyst is completely embedded in the uterus wall, a plug called a fibrin coagulum forms in the gap created in the epithelium of the uterus by the blastocyst. At this time, the growth of the cytotrophoblast and syncytiotrophoblast is much faster than that of the bilaminar embryonic disc
Small holes called lacunae begin to form in the syncytiotrophoblast as it continues to expand.
Day 12
Capillaries in the endometrium surrounding the developing embryo dilate, forming maternal sinusoids. As the lacunae continue to expand, enzymes within the syncytiotrophoblast begin to erode the lining of the sinusoids and uterine glands. This allows anastomosis between the maternal sinusoids and lacunar networks to begin establishment of an uteroplacental circulation.
By day 12, the lacunae stop growing and fuse to form large interconnecting spaces, called lacunar networks.
A new population of cells appears between the inner surface of the cytotrophoblast and the outer surface of the primitive yolk sac, known as the extraembryonic mesoderm.
Large cavities begin to appear in the extraembryonic mesoderm. These gradually fuse to form one single cavity, called an extraembryonic coelom.
Day 13
Approximately 13 days after fertilization, a large portion of the exocoelomic cavity is pinched off, forming a smaller cavity, called the secondary yolk sac. A remnant also forms within the exocoelomic cavity, known as an exocoelomic cyst, which is eventually eliminated.
By the end of the second week of development, the chorionic cavity enlarges, and the bilaminar embryonic disc is joined to the trophoblast by a band of extraembryonic mesoderm called the connecting stalk.

Embryology
Embryology (from Greek ἔμβρυον, embryon, "the unborn, embryo"; and -λογία, -logia) is the branch of biology that studies the development of gametes (sex cells), fertilization, and development of embryos and fetuses. Additionally, embryology is the study of congenital disorders that occur before birth.
Embryonic development of animals
After cleavage, the dividing cells, or morula, becomes a hollow ball, or blastula, which develops a hole or pore at one end.
Bilaterals
In bilateral animals, the blastula develops in one of two ways that divides the whole animal kingdom into two halves (see: Embryological origins of the mouth and anus). If in the blastula the first pore (blastopore) becomes the mouth of the animal, it is a protostome; if the first pore becomes the anus then it is a deuterostome. The protostomes include most invertebrate animals, such as insects, worms and molluscs, while the deuterostomes include the vertebrates. In due course, the blastula changes into a more differentiated structure called the gastrula.

Embryonic folding is the process of converting the embryo from a flat disc, into a cylinder.
This cylinder consists of three main layers, derived from the trilaminar embryonic disc: the endoderm in the center, the ectoderm on the outside, and the mesoderm, which is found between the two layers.
During the fourth week of development, folding of the embryo occurs as a result of the differential rates of growth of the embryonic structures. The embryonic disc and amnion grow rapidly, however, growth of the yolk sac is much slower.
Embryonic folding occurs in two planes: the horizontal plane, which results in the development of two lateral body folds, and the median sagittal plane, which causes the longitudinal cranial (head fold) and the caudal (tail fold) of the embryo to develop.
As folding continues simultaneously in both planes, the result is a very rapid development of the embryo.
The endoderm of the trilaminar disc is mainly responsible for the formation of the epithelial lining and glands of the gastrointestinal tract. As the lateral, cranial and caudal folds of the endoderm fold towards the midline, they fuse, incorporating the dorsal part of the yolk sac to create the primitive gut tube.
The gut tube is divided into three main parts: the foregut, midgut, and hindgut.
The foregut can be seen at the cranial end of the embryo and is temporarily closed by a membrane, called the oropharyngeal membrane. At the end of the fourth week of development, the oropharyngeal membrane ruptures to connect the future oral cavity with the pharynx.
Until the fifth week of development, the midgut is connected to the yolk sac, which narrows into a stalk known as the vitelline duct, as embryonic folding continues. Eventually, the yolk sac constricts and detaches from the midgut, and the midgut seals.
The caudal end of the hindgut is also temporarily closed by a membrane, called the cloacal membrane, which separates the upper and lower parts of the anal canal.
The cloacal membrane ruptures during the seventh week of development to form the urogenital and anal openings.
The ectoderm covers the entire outer surface of the developing embryo, except for the eventual umbilical region.
This germ layer, along with the dermatomes, lateral plate mesoderm, and neural crest cells formed during neurulation, eventually form the skin, as well as several other vital structures, including the central and peripheral nervous systems.
The mesoderm germ layers organize into somites, which eventually give rise to muscle tissue, cartilage, bone, and subcutaneous tissue of the skin.
As a result of embryonic folding, the major body plan becomes established, and the three germ layers continue to differentiate, giving rise to their own tissues and organ systems.

By the end of the second week of development, the bilaminar embryonic disc, consisting of the hypoblast and epiblast, has formed.
Throughout the third week of development, this bilaminar disc differentiates to establish three primary germ layers, in a process known as gastrulation.
Approximately 15 days after fertilization, a thickened structure forms along the midline in the epiblast, near the caudal end of the bilaminar embryonic disc. This is called the primitive streak.
At this stage, the formation of the primitive streak defines the major body axes of the embryo, including the cranial end (towards the head) and caudal end (towards the tail) as well as the left and right sides of the embryo.
At the cranial end of the embryonic disc, the primitive streak expands to create a primitive node, which contains a circular depression, known as a primitive pit. The primitive pit is continuous with a groove, known as the primitive groove, which runs caudally along the midline of the primitive streak.
Once the primitive groove has formed, cells of the epiblast migrate inwards towards the streak, detach from the epiblast, and slip beneath into the interior of the embryonic disc. This process is known as invagination.
The first cells to invaginate through the primitive groove invade the hypoblast, and displace its cells. The hypoblast cells are eventually completely replaced by a new cell layer, which is referred to as the definitive endoderm.
By day 16, the majority of the hypoblast has been replaced. Some of the invaginated epiblast cells remain in the space between the epiblast and newly formed definitive endoderm.
These cells form a germ layer known as the mesoderm, which subsequently forms the notochord, the basis for the axial skeleton.
Once the formation of the definitive endoderm and mesoderm is complete, epiblast cells no longer migrate towards the primitive streak.
At this point, the remaining cells of the epiblast are referred to as the ectoderm, and form the third germ layer.
The ectoderm forms from the cranial to the caudal end of the embryo, such that by the end of the third week, the three primary germ layers complete the embryonic disc.
The gastrulation process is finally complete.

Implantation of the blastocyst usually occurs 6-8 days after fertilization.
By day 8, the blastocyst has burrowed into the uterine wall, being completely embedded by day 9.
Day 8
The blastocyst is composed of two main components: the outer cell mass, the trophoblast; and the inner cell mass, the embryoblast.
As the trophoblast makes contact with the endometrium, it differentiates into two layers: an inner, cytotrophoblast; and an outer, syncytiotrophoblast.
The embryoblast differentiates into a bilaminar embryonic disc composed of two cell layers, the hypoblast, and the epiblast. Soon after the embryonic disc has formed, a cavity begins to appear between the epiblast and cytotrophoblast, known as the amniotic cavity.
Cells originating from the hypoblast begin to migrate, forming a thin membrane, which lines the inner surface of the cytotrophoblast. This is called the exocoelomic membrane. The exocoelomic membrane and cells of the hypoblast together form the walls of the primitive yolk sac.
Day 9
Once the blastocyst is completely embedded in the uterus wall, a plug called a fibrin coagulum forms in the gap created in the epithelium of the uterus by the blastocyst. At this time, the growth of the cytotrophoblast and syncytiotrophoblast is much faster than that of the bilaminar embryonic disc
Small holes called lacunae begin to form in the syncytiotrophoblast as it continues to expand.
Day 12
Capillaries in the endometrium surrounding the developing embryo dilate, forming maternal sinusoids. As the lacunae continue to expand, enzymes within the syncytiotrophoblast begin to erode the lining of the sinusoids and uterine glands. This allows anastomosis between the maternal sinusoids and lacunar networks to begin establishment of an uteroplacental circulation.
By day 12, the lacunae stop growing and fuse to form large interconnecting spaces, called lacunar networks.
A new population of cells appears between the inner surface of the cytotrophoblast and the outer surface of the primitive yolk sac, known as the extraembryonic mesoderm.
Large cavities begin to appear in the extraembryonic mesoderm. These gradually fuse to form one single cavity, called an extraembryonic coelom.
Day 13
Approximately 13 days after fertilization, a large portion of the exocoelomic cavity is pinched off, forming a smaller cavity, called the secondary yolk sac. A remnant also forms within the exocoelomic cavity, known as an exocoelomic cyst, which is eventually eliminated.
By the end of the second week of development, the chorionic cavity enlarges, and the bilaminar embryonic disc is joined to the trophoblast by a band of extraembryonic mesoderm called the connecting stalk.
