The dermis is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that consists of connective tissue and cushions the body from stress and strain. It is divided into two layers, the superficial area adjacent to the epidermis called the papillary region and a deep thicker area known as the reticular dermis. The dermis is tightly connected to the epidermis through a basement membrane. Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix. It also contains mechanoreceptors that provide the sense of touch and thermoreceptors that provide the sense of heat. In addition, hair follicles, sweat glands, sebaceous glands, apocrine glands, lymphatic vessels and blood vessels are present in the dermis. Those blood vessels provide nourishment and waste removal for both dermal and epidermal cells.
The dermis is composed of three major types of cells:fibroblasts, macrophages, and adipocytes.
Apart from these cells, the dermis is also composed of matrix components such as collagen (which provides strength), elastin (which provides elasticity), and extrafibrillar matrix, an extracellular gel-like substance primarily composed of glycosaminoglycans (most notably hyaluronan), proteoglycans, and glycoproteins.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Crash Course (also known as Driving Academy) is a 1988 made for television teen film directed by Oz Scott.
Crash Course centers on a group of high schoolers in a driver’s education class; many for the second or third time. The recently divorced teacher, super-passive Larry Pearl, is on thin ice with the football fanatic principal, Principal Paulson, who is being pressured by the district superintendent to raise driver’s education completion rates or lose his coveted football program. With this in mind, Principal Paulson and his assistant, with a secret desire for his job, Abner Frasier, hire an outside driver’s education instructor with a very tough reputation, Edna Savage, aka E.W. Savage, who quickly takes control of the class.
The plot focuses mostly on the students and their interactions with their teachers and each other. In the beginning, Rico is the loner with just a few friends, Chadley is the bookish nerd with few friends who longs to be cool and also longs to be a part of Vanessa’s life who is the young, friendly and attractive girl who had to fake her mother’s signature on her driver’s education permission slip. Kichi is the hip-hop Asian kid who often raps what he has to say and constantly flirts with Maria, the rich foreign girl who thinks that the right-of-way on the roadways always goes to (insert awesomely fake foreign Latino accent) “my father’s limo”. Finally you have stereotypical football meathead J.J., who needs to pass his English exam to keep his eligibility and constantly asks out and gets rejected by Alice, the tomboy whose father owns “Santini & Son” Concrete Company. Alice is portrayed as being the “son” her father wanted.

Plot: Webb Wilder descends into a southern gothic underworld flush with casino cash, trailer trash, and raw-boned violence to rescue his congenitally misinformed nephew from rural mobsters. A full time roots rocker, part-time private eye, Webb Wilder receives an SOS from his nephew Abner when 'organized thugs' intent on collecting on mounting gambling debts kidnap Abner's girlfriend, Wanda. Accompanying Webb on his rescue mission is record company A & R (Artist and Repertory) man, Pippin Moss; an ethics-challenged entertainment industry manipulator intent on signing Webb to a new contract. Tracking down Abner leads Webb and Pippin to Pineopolis County, Mississippi, a contemporary miasma of roadside fruit stands, dirt track car racing and murky agrarian crime where "good and evil, black and white bleed into gray in a minute and darkness sometimes catches the angels nappin'."

Hair has a characteristic sexual distribution in humans varying between males and females. The purpose of hair on the head is probably to protect the head and the body against direct sunlight. Hair also increases the sensitivity of the skin to touch. There is also some social aesthetic function, especially in females. Hair follicles house the hairs and are fairly deep structures that go down into the dermis. The hair follicles are lined with an infolding of the epidermis. Sebaceous glands produce sebum and deposit this product in the hair follicles, th...

www.Medical3DAnimationCompany.com Email us: solutions@Medical3DAnimationCompany.com Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue. This flythrough of the anatomy of skin was used for a video that depicted the damage caused by various types of burns. By showing the interior structures, the extend of the damage could be more clearly understood by the student.

He walked 300 miles
Just to bring me bread
His body like a sculpture
Almost decorated
and I’ll wake him as the dawn does
and we’ll break it on the bus
saying, “this was made for us, love”
In lovers communion for 500 miles
And in 500 miles will he break
Break me again?
In lovers communion for 500 miles
And in 500 miles will we brake
Even break
Step it up
Grab your phone
Get your suitcase
There is no time to waste
A big adventure awaits
Sad news, France suffered a late snow
The blooms break through the ice
In San Francisco
A guitar man finally confessed
He left that actress
Over the lakes with hearts touched by frost
We fought in the Land of the Midnight Sun
I lost myself
I lost myself
I walk 300 miles
Just to bring
To bring him bread
In love some gifts are simple
Others I underrated
So I’ll wake him as the dawn does
And we’ll face what any lovers must
Blueness pales within a flames lust
In lovers communion for 500 miles
And in 500 miles will he break
Break me again?
In lovers communion for 500 miles
And in 500 miles will he brake
Even break
will we brake
Even break
Brake
Even brake
Don’t slow down
