Q

Features of a typical lining

A

Free surface: lining of epithelium should not be associated with anything, hallow tubes usually

Densely Paced epithelia cells

Basements Membrane: Epithelium w/ CT

Nearby loose CT

Q

Identify each type of intercellular JXN

A

TJ: rescrtive seal, combining two adjacent cells

Adherent jxn: anchors the cells to neighboring cells

Desmosomes: Resist Mechanical Stress composed of intermediate filaments

Gap Jxn: channel that allows for communication between cells, NOT IMAGED HERE

Q

Identify the difference between Epithelium and CT what is is called

It has how many sections what are those sections

A

Basement Membrane

The basal lamina is associated w/ the epithelial side and Reticular Lamina is associated w/ CT side
