skeletal system
shaft of long bone and ends of long bone
what is diaphysis and epiphysis
what is the axial skeleton
what is skull, hyoid, vertebrae, ribs, sternum
functional classes aka S.A.D
synarthosis, amphiarthosis, diarthosis
properties of muscle tissue
excitable, contractile, extensible, elastic
muscles change length while tension stays the same (lifting a dumbbell or squatting)
what is isotonic
growth plate zones in order
whats is resting, proliferation, hypertrophic, calcification, ossification
whats is the appendicular skeleton
what is arms, legs, pelvic, pectoral girdles
what is ligaments
Dense regular connective tissue that anchors bone to bone
types of muscles
what is skeletal, smooth, cardiac
muscle does not change length, but tension increases (holding a plank or pushing against a wall)
what is isometric
outer covering (contains blood vessels and osteoblasts)
