Cards Term Supraspinatus Muscle Definition inn. suprascapular n. function: abduction of arm Term Infraspinatus Muscle Definition inn. suprascapular nerve function: lateral rotator of arm Term Teres Minor Definition inn. Axillary nerve function: lateral rotator of arm Term Subscapularis Muscle Definition inn. subscapular nerve function: arm adduction and medial rotation Term Rotator Cuff Muscles Definition supra+infra spinatus teres minor subscapularis Function:helps maintain stability of shoulder joint Term Deltoid Muscle Definition inn. Axillary n. function: Most important abductor of arm up to 90 degree Term Teres Major Definition inn. lower subscapular n. Function: adductor and medial rotator of arm Term Latissimus Dorsi Definition inn. Thoracodorsal Nerve Function: adduction, medial rotation and extension of arm Term Coracobrachialis Definition inn. Musculocutaneous Never Function: flexion and adduction of arm Origin: coracoid process Term Pectoralis minor Definition inn. medial pectoral never fuction: lowers and rotates scapula Term pectoralis major Definition inn. lateral and medial pectoral nerve function: adduction and medial rotation of humerous Term serratus anterior muscle Definition inn. long thoracic nerve function: elevation of arm over 90 degrees nerve can be damaged during a radical mastectomy paralysis of nerve causes winged scapula, cannot lift arm beyond 90 degrees however if damaged to rhomboid, winged scapula is seen but no abnormal arm elevation Term subclavous muscle Definition inn. Nerve to subclavous function: pulls clavicle towards sternum central vein catheter would be inserted through muscle Term Biceps Definition inn. musculocutaneous n. long head is adductor and medial rotator of arm short head is adductor of arm both heads flex at shoulder joint. strong supinator at shoulder joint orgin: coracobrachialis Term brachialis Definition inn. musculocutaneous nerve fuction: powerful flexor of elbow joint Term Triceps Definition inn. radial nerve chief extensor of elbow joint Term anconeus Definition inn. radial nerve assists triceps Term injury to radial n. Definition wrist drop Term Erb-Duchenne paralysis (c5-c6) Definition pulling arm at birth or falling on shoulder may damage upper part of brachial plexus and cause roots to be pulled out of spinal cord. Signs: no arm abduction, no elbow flexion, weak supination Term hyperflexion Definition occurs from upper motor neuron injury in brain. too much response Term hypoflexia Definition peripheral nerve damage. no reflex Term Klumpke's Paralysis Definition injury to c8-c1 roots followed forced abduction of shoulder. Signs: Clawhand and often sympathetic palsy. ulnar part of hand is damaged Term damage to axillary nerve Definition damaged by: shoulder dislocation, limited brachial neuritis. Results in weakness of abduction of shoulder between 15-90 degrees and sensory loss over outer aspect of shoulder Term pronator teres Definition inn. median nerve. fuction: pronation of arm and flexion of elbow Term palmaris longus Definition inn. median n. fuction: flexes hand towards palm Term flexor carpii radialis Definition inn: median n. function: palmar flexioin and radial abduction of hand runs through carpal tunnel Term flexor digitorum superficialis Definition inn. median n. function: strong flexors of finger runs through carpal tunnel Term flexor carpii ulnaris Definition inn: ulnar n. fuction: hand flexion and adduction Term flexor digitorum profundus Definition inn.median nerve function:flexor runs through carpal tunnel Term pronator quadratus Definition median n. pronates forearm Term Papal Benediction Sign Definition 2 fingers only have flexion of median n. is damaged Term Continents of Carpal Tunnel Definition Flexor Digitorum Profundus Flexor digitorum Superficialis Flexor pollicis longus Median Nerve Term Brachioradialis Definition inn. Radial Nerve function: flexor Term extensor carpii radialis longus Definition inn. radial nerve extensor and abductor of hand at wrist Term extensor carpii radialis brevis Definition inn. radial nerve extensor and abductor at wrist Term Golfer's Elbow Definition medial epicondylitis Term Tennis elbow Definition lateral epicondylitis Term extensor digitorum Definition inn. radial interosseous branch fuction: extends metacarpophalangeal. strong dorsiflexor of hand at wrist Term extensor digiti minimi Definition inn. interosseous branch of deep radial n. function: extension of 5th digit Term extensor carpii ulnaris Definition inn. post. interosseous branch of deep radial fuction extends and adducts hands Term supinator Definition deep branch of radial n supinates Term abductor pollicis longus Definition radial post. int deep abduction of thumb plus extension at metacarpal joint Term extensor pollicis brevis Definition int post. deep. radial extension of pinky at metacarpal joint Term extensor pollicis longus Definition post. int. deep radial extends thumb Term extensor indicis Definition post. int. deep brach radial index extension and hand dorsiflexion Term extensor retinaculum Definition covers carpal bones. 6 tendon compartments through which extensor muscles and abductor pollicis longus pass Term ape hand Definition dislocation of lunate can cause ape hand. medial n. injury causes ape hand Term abductor pollicis brevis Definition median n abduction of thumb Term flexor pollicis brevis Definition median n. flexes thumb Term adductor pollicis Definition 2 heads ulnar n. thumb adduction Term opponens pollicis Definition median n. thumb opposition Term palmaris brevis Definition ulnar n Term abductor digiti minimi Definition ulnar n. abducts pinky Term opponens digiti minimi Definition ulnar n. makes oppostion of pinky to thumb possible Term palmar muscle Definition 3 muscles ulnar n. adduction of digits Term dorsal interossei Definition 4 muscles ulnar n. abduction of digits Term lumbricals Definition 4 muscles lateral inn by median n. medial inn by ulnar n.
