narrow muscle medial to and parallel with the extensor pollicis longus,
originates on the posterior surface of the ulna, inserts on the tendon
of the extensor digitorum of the index finger; extends distal and
middle phalanges (look in, overshadowed by minimi and digitorum)
Give this one a try later!
extensor indicis
,inserts on medial border and superior angle of scapula; adducts
scapula (from scapula--> neck)
Give this one a try later!
levator scapulae
originates from the dorsal surface of the radius; extends the first
phalanx of the thumb and abducts the hand
Give this one a try later!
extensor pollicis brevis
four slender, worm-like muscles in the palm of the hand, originates on
the lateral sides of the tendons of the flexor digitorum profundus,
inserts on the tendons of the extensor digitorum on proximal
phalanges of each finger; flex and extend each finger (between digits,
metacarpals)
Give this one a try later!
, lumbricals
small muscle in armpit region; flexes and adducts humerus
synergistically with pectoralis major
Give this one a try later!
coracobrachialis
two headed muscle on the anterior side of the upper arm; elbow
flexor and forearm supinator
origin: supraglenoid tubercle and coracoid process
insertion: radial tuberosity
action: flexes elbow and shoulder; supinates forearm
Give this one a try later!
biceps brachii
anterior upper arm (most lateral)
Give this one a try later!
