Document Summary
Body composition: 4 basic tissues: epithelia, based on cell morphology & number of layers, nervous tissue, main component of brain, spinal cord and nerves, muscle tissue, contractile, controlled voluntarily and involuntarily, connective tissue, proper. Dense; ligaments and tendons, resists mechanical stress: blood. Transports respiratory gas, nutrients and wastes: bone. Fat storage, passage for nerves and blood vessels. Surrounds individual & groups of muscles, large vessels and nerves: reduces friction during contractions, organizes muscular groupings. Joints: articulations, where 2 or more bones come together to increase stability and mobility. Fibrous joints: connected by dense regular connective tissue, lack a joint cavity: sutures: immovable, located between skull bones, syndesmoses: connected ligaments, movement range depends on length, gomphoses: peg-in-socket for root of tooth. Cartilaginous: bones united by cartilage; lack a joint cavity: synchondroses: hyaline cartilage, symphyses: fibrocartilage; slightly moveable. Synovial: fluid filled, many are free movable: nonaxial: plane joint, gliding does not involve rotation, uniaxial: hinge and pivot.
