O=supracondylar ridge of humerus
I=base of 2nd metacarpal
A=wrist extension & radial deviation
Extensor carpi radialis longus
O=lateral supracondylar ridge of the humerus (distal)
I=styloid process of radius (distal)
A=elbow flexion
Brachioradialis
O=distal 1/2 of the anterior humerus
I=coronoid process/ulnar tuberosity
A=elbow flexion
Brachialis
Attachment for biceps
Radial tuberosity
O=lateral epicondyle of humerus
I=base of 5th metacarpal
A=wrist extension & ulnar deviation
Extensor carpi ulnaris
What do the flexor carpi ulnaris & the extensor capri ulnaris do?
Ulnar deviation
O=lateral epicondyle of humerus
I=base of 3rd metacarpal
A=wrist extension & assists with radial deviation
Extensor carpi radialis brevis
Where does the extensor carpi radialis longus attach?
Supracondylar ridge
What does the flexor carpi radialis & the extensor carpi radialis longus
Radial deviation
What is a common extensor tendon attachment
Lateral epicondyle
O=long head-supraglenoid tubercle Short head- coracoid process I=radial tuberosity A=assist with shoulder flexion, elbow flexion, & forearm supination
Biceps brachii
What are the bicep brachii & supinator
Supinators
What joints superior end pivots while the distal end moves around the ulna?
Radioulnar joint
Articulates with the trochlea of the humerus and is also called the semilunar notch
Trochlear notch
O=lateral epicondyle of the humerus
I=lateral & inferior to olecranon process of ulna
A=not a prime mover in any joint action. Used as a
stabilizer in pronation & supination
Anconeous
O=medial epicondyle of humerus
I=palmar fasica
A=assist with wrist flexion (not very strong)
Palmaris longus
What joints proximal ends consists of the radius
& radioulnar disk; and the distal end made of the scaphoid, lunate, triquetrum
Radiocarpal joint
