Chapter 5 Tissues Flashcards
Cells of similar type and function clustered into layers, sheets, or groups
Tissues
Four types of tissue
Epithelial, Connective, Muscle, Nervous
Tissue that covers and lines
Epithelial tissue
Tissue that provides support
Connective tissue
Tissue that enables movement
Muscle tissue
Tissue that controls work
Nervous tissue
Side of the cell that faces the lumen
Apical surface
Side of the cell that faces the underlying connective tissue
Basal surface
Epithelial cells; vascular or avascular?
Avascular
Foundation of the epithelial cell
Basement membrane
What is the purpose of a brush border?
Increases surface area thus absorptive ability
Waterproof substance that protects epithelial cells
Keratin
Fusion of the outermost layer of the plasma membranes of adjoining cells; matrix filled space is lost
Tight junction
Strong, welded plaque that connects the plasma membranes of adjacent cells
Desmosome
Cells connected by tubular channel proteins
Gap junctions
