elbow and forearm muscles Flashcards
anconeus: MA
assists triceps in extending elbow
stabilizes elbow joint
may abduct ulna during pronation
anconeus: PA
lateral epicondyle of humerus
anconeus:DA
lateral surface of olecranon and superior part of posterior surface of ulna
anconeus: IN
radial (C7, C8, T1)
supinator: MA
supinator the forearm
supinator: PA
lateral epicondyle of humerus
radial collateral and angular ligaments
supinator fossa
crest of ulna
supinator: DA
lateral, posterior and anterior surfaces of proximal third of radius
supinator: IN
radial never (C7 and C8)
pronator teres: MA
pronate the forearm
assists to flex the elbow
pronator teres: PA
common flexor tendon from medial epicondyle of humerus
coronoid process of the ulna
pronator teres: DA
middle of convexity of lateral surface of radius
pronator teres: IN
median nerve (C6, C7)
flexor carpi radialis: MA
flex the wrist
radial deviation (abduct hand at wrist)
flexor carpi radialis: PA
medial epicondyle of humerus
flexor carpi radialis: DA
bases of 2nd and 3rd metacarpals
flexor carpi radialis: IN
median (C6, C7)
palmaris longus: MA
tense the palmar aponeruosis
flex the wrist (radiocarpal joint)
palmaris longus: PA
medial epicondyle of humerus
palmaris longus: DA
flexor retinaculum and palmar aponeurosis
palmaris longus: IN
median C7 and C8
flexor carpi ulnaris: MA
flex the wrist
ulnar deviation
flexor carpi ulnaris: PA (Humeral head)
common flexor tendon from medial epicondyle of humerus
flexor carpi ulnaris: PA (ulnar head)
posterior surface of proximal 2/3rds of ulna
flexor carpi ulnaris: DA
pisiform, hook of the hamate, and base of 5th metacarpal
flexor carpi ulnaris: IN
ulnar (C7 and C8)
pronator quadratus: MA
pronate the forearm
deep fibers bind the radius and ulna together
pronator quadratus: PA
medial, anterior surface of distal ulna
pronator quadratus: DA
lateral, anterior surface of distal radius
pronator quadratus: IN
median nerve (C8 and T1)
