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 medical education video “Surface of Epithelial Cells” is part of the lecture “Connective Tissue: Epithelium” of the online medical course “Types of Tissues”. It provides you with an excellent overview of the surface anatomy of epithelia.
You will learn more about:
• Infoldings (plicae)
• Interdigitating cytoplasmic projections of adjacent cells
• Cell interdigitation
• Basal surface of epithelial cells
• Basal infoldings
• The way to increase surface area
Now it’s your turn! Watch the video and find out the correct answer to the following question:
