Your lecturer is
Professor Geoff
Meyer. He is currently teaching at the
School of
Anatomy, Physiology and
Human Biology at the
University of Western Australia (
UWA). As an leading anatomy and histology expert he is also coordinator of the Federative
International Program for Anatomical Terminologies (FIPAT) of the
International Federation of Associations of Anatomists (
IFAA). Aside from medical research on the ovarian
function, steroidogenesis, corpus luteum, angiogenesis and microcirculation Geoff Meyer’s research activities focus on developing innovative, computer-aided learning and teaching tools. Being such innovative, Geoff Meyer has received a number of awards for his work, including the
Australian University Teaching
Award.
The video “Epithelial
Cell Polarity” is part of the lecture “
Connective Tissue: Epithelium” of the online medical course “Types of Tissues”. It gives you an excellent insight into epithelial cell polarity and different surface modifications.

•
Epithelial cell polarity
-
Apical domains
- Lateral domains
- Basal domains
•
Surface modifications of epithelial cells
- Microvilli (brush border)
- Stereocilia
- Cilia
•
Structure of microvilli and their function
-
Actin filaments
- Fimbrin
- Villin
- Plasmalemma
- Lateral extensions
-
Linkage to cell membrane
• Structure of stereocilia and their function
• Structure of cilia and their function
-
