Document Summary

Dendrites: generally short multi-branched projections of the cell membrane that receive the action potentials allowing the impulse to move into the cell body. Axon (nerve fiber): one per cell and is long, thin with a consistent diameter and conducts action potentials away from the cell body: neuroglia: support cells that nourish, protect and insulate neurons. Contains epithelial cells and thick layer of loose connective tissue (called lamina propria) Contain goblet cells or mucous glands that secrete mucus on epithelial surfaces to keep moist: serous membranes: membrane that does not open to exterior and lines cavities - i. e pericardial sac. Doesn"t contain glands but contains mesothelium (single layer of simple squamous epithelium), a basement membrane, and a delicate layer of loose connective tissue. Acts as selective permeability barrier: synovial membranes: membrane that is only made of connective tissue that line freely moveable joints.
