Document Summary
Tissue classification: based on: structure of cells, composition of extracellular matrix, cell function. Tissue types: epithelial (typical tissue diagram with basement membrane, connective (super weird, muscular (long strands, red, nuclei distributed randomly in cells, multiple nuclei, nervous (picture neuron) **** shape determined by apical cells: free surfaces: include microvilli (increase surface area), cilia (move material) Can be: unicellullar: goblet cells (single cells that release material, multicellular: many cells that form discrete structure/whole organ, ex. Cells that affect extracellular matrix: _____ blasts: create matrix by producing material and pushing it out, osteoblast (bone, _____cytes: maintain matrix, chondrocyte (cartilage, _____clasts: break matrix down for remodeling, osteoclasts. Classification of connective tissue: embroyonic: only found in embryo, mesenchyme (basic tissue in embryo, becomes all mature tissue, mucous (in umbilical cord, mature, loose, aerolar, reticular, adipose, dense, regular, irregular, elastic, cartilage, elastic, hyaline, fibrocartilage, bone, blood. Membranes: flat sheets of pliable tissue, cover/line body part.
