GENERAL Tissue = Cells with similar structure & function organized into groups or layers Four major types: - Epithelial (Covers or lines surfaces) - Connective (Bind & support body parts) - Muscle (Movement) - Nervous (Detect changes & transmit info.)

CHARACTERISTICS OF EPITHELIAL TISSUE Many tightly packed cells, usually arranged into layers Functions: protection, absorption, sensation, secretion High rate of cell division (healing) Avascular (rely on diffusion)

CLASSIFICATION OF EPITHELIAL TISSUE Layers - Simple (one layer) - Stratified (>1 layer; Note: only cells at surface have characteristic shape) Shapes - Squamous - Cuboidal - Columnar - Transitional
