Document Summary
There are 4 main types of tissue: epithelial- for covering connective- for support muscle- for movement nervous- for control and regulation. Usually, all 4 tissues make up an organ (at least 2 tissue types are required, but organs with. 4 types of tissue are most common) histology- the study of tissues (their organization, appearance, etc. : epithelial tissue. A sheet of cells that covers a body surface or lines a body cavity. Functions of epithelia: protection- creates a physical boundary (i. e. : skin); allows for mechanical, chemical and infectious protection. Tight junctions: individual cell membranes fused tightly together; helps keep proteins and apical regions of the plasma membrane from diffusing into the basal region, and thus help to maintain epithelial polarity. Also acts as a scaffolding along which epithelial cells can migrate to repair a wound. Provides attachment site for epithelial cells and allows for organization.
