Week three OIA Upper E Flashcards
Origin of Bicep
Short head: coracoid process
Long head: supraglenoid tubercle
Insertion of bicep
radial tuberosity and bicipital aponeurosis
Action of bicep
flexion of the elbow and shoulder, supination of the forearm
Origin of tricep
Long: infra glenoid tubercle
Lateral: post, approx 1/2 of humerus
Medial: post, distal 1/2 humerus
Insertion of tricep
olecranon process
Action of tricep
All: Extend elbow
Long: extension and adduction of the shoulder
Origin of brachialis
anterier, distal 1/2 humerus
Anterior to the distal 1/2
Insertion of brachialis
tuberosity and coronoid of the ulna
Tub of coors Light
Action of brachialis
flexion of elbow
Origin of anconeus
lateral epicondyle of the humerus
Insertion of anconeus
olecranon process, the lateral edge of the ulnar shaft
Anconeus = olacronon process
Action of anconeus
extension of elbow
Origin of brachioradialis
proximal 2/3 lateral supracondylar ridge of humerus
Insertion of brachioradialis
radial styloid process
Radialis = radialis
Action of brachioradialis
Flexion of the elbow assists in resisted supination and pronation
Origin of Supinator
lateral epicondyle of the humerus. Radial collateral ligament. Annular ligament.
Laterale is epic, radial is cold and annular eclips.
Insertion of Supinator
Anterior, lateral surface of proximal 1/3 radius
Action of Supinator
supination of forearm
Origin of extensor carpi radialis longus
Distal 1/3 of the lateral supracondylar ridge of the humerus
Lateral is super distal to 1/3 of the ridge
Insertion of extensor carpi radialis longus
The base of 2nd metacarpal, dorsal surface
Action of extensor carpi radialis longus
extension and abduction of the wrist, flexion of elbow
Origin of extensor carpi radialis brevis
common extensor tendon lateral epicondyle of humerus
Insertion of extensor carpi radialis brevis
The base of 3rd metatarsal
Action of extensor carpi radialis brevis
Extension and abduction fo wrist, assist in flexion of elbow
Origin of Extensor pollicis Brevis
posterior surface of radius and interosseous membrane
Insertion of Extensor pollicis Brevis
The base of the proximal phalange of the thumb
Action of Extensor pollicis Brevis
extension of thumb and CMC and MCP, abduction of wrist
Origin of Extensor pollicis longus
Posterior surface of middle 1/3 of ulna
Insertion of extensor pollicis longus
Base of distal phalange of thumb
Action of extensor pollicis longus
Extension of thumb, CMC and MCP, IP. Abduction of wrist.
Origin of extensor carpi ulnaris
common extensor tendon, lateral epicondyle of humerus
Insertion of extensor carpi ulnaris
base of 5th metacarpal
Carpi = 5
Action of extensor carpi ulnaris
extension and adduction of wrist
Origin of extensor digitorum
common extensor tendon, lateral epicondyle of humerus
Insertion of extensor digitorum
middle and distal phalanges of 2-5th fingers
Action of extensor digitorum
extends 2-5 fingers. Assist in the extension of the wrist
Origin of extensor digiti minimi
common extensor tendon, lateral epicondyle of humerus
Insertion of extensor digiti minimi
middle and distal phalange of 5th finger
Action of extensor digiti minimi
extension of 5th finger, assist in extension and adduction of wrist
Origin of extensor indicis
posterior surface of distal shaft of ulna
Insertion of extensor indicis
Tendon of extensor digitorum at level of 2nd metacarpal
Action of extensor indicis
Extension of 2nd finger, assist to adduction 2nd finger
