CLASSIFICATION OF TISSUES:
EPITHELIAL TISSUE
* covers exposed surfaces & lines internal passageways & forms glands * Cells have apical (free) surface & basal surface * cells fit together to form membranes (sheets) & supported by connective tissue * Cells are avascular & have a basal membrane * Classification is based on 1) number or arrangement of layers & 2) cell shape.
