Mesothelium is…
the epithelium that lines the walls and covers the contents of the closed cavities of the body (i.e., the abdominal, pericardial, and pleural cavities
Five functions of epithelium.

Transepithelial transport.
Microvilli are more abundant and tightly packed on cells that are highly active in…?
Transepithelial transport.
What is microvilli composed of?
20-30 actinfilaments, packed by actin-bundling proteins. Such as fascin, fimbrin and espin.
Which protein binds the actinfilaments to the plasma membrane of the microvilli?
Myosin I
Name a part of the body where you find stereocilia.
Inner ear. Among others.
Name the three different kinds of cilia.
Motile cilia, Primary cilia, Nodal cilia.
What is the cause of ciliary movement?
Dynein of one microtubule-doublet attaches to an adjacent doublet and uses ATP to slide along the microtubuli.
What is primary cilia useful for?
Cell-signaling.
What are CAMs?
Cell-adhesion molecules.
Name the three types of junctional complex.
Occluding junctions, anchoring junctions, communicating junctions.
