anatomy final exam:A

joints/mov't-actions/brachial plexus/muscular/skeletal sys/miscell

ball & socket (shoulder) Glenohumeral joint: capable of circumduction.
ellipsoid (partial of wrist) Radiocarpal joint: permits flexion & extension, adduction & abduction.
hinge (elbow) Humeral joint: allows ONLY flexion & extension
saddle (Trapezium & 1st metacarpal) modified Ellipsoid joint: composed of Convex & Concave articulating surfaces.
gliding (magority of wrist) between 2 flat surfaces allows the least mov't of all synovial joints(wrist:carpal bones/ foot: tarsal bones)
pivot joint atlantoaxial joint: (behind neck- 1st & 2nd cervical) allows 1 bone to rotate surface of another bone. example rotating neck
adduction moving midally or towards tht midline
abduction lateral away from midline
inversion sole of foot moves medially
eversion sole of foot moves laterally
plantar flexion walking on your tipitoes
dorsi flexion walking on your heals
supination palm up/anterior side up
pronation palm down/posterior side up
