wrist muscles Flashcards
which wrist muscles attach at the medial epicondyle
flexor carpi radialis, flexor carpi ulnaris, palmaris longus
which wrist muscles attach at the lateral epicondyle
extensor carpi radialis brevis, extensor carpi ulnaris
what are the wrist muscles
flexor carpi radialis, flexor carpi ulnaris, palmaris longus, extensor carpi radialis longus, extensor carpi radialis brevis, extensor carpi ulnaris
what does the flexor carpi radialis do
wrist flexion, radial deviation
what does the flexor carpi ulnaris do
wrist flexion and ulnar deviation
what does the palmaris longus do
wrist flexion
flexor carpi radialis attachments
medial epicondyle -> radial hand (2nd and 3rd metacarpals)
palmaris longus attachments
medial epicondyle -> palm of hand (palmaris aponeurosis)
flexor carpi ulnaris attachments
medial epicondyle, medial border of olecranon and medial border of ulna -> ulnar hand (pisiform, hook of hamate, 5th metacarpal)
ulnar nerve runs beneath the two heads of what muscle

extensor carpi radialis longus attachments
LATERAL SUPRACONDYLAR ridge -> 2nd metacarpal (radial hand)
extensor carpi radialis Brevis attachments
lateral epicondyle -> base of the 3rd metacarpal radial hand
extensor carpi ulnaris attachments
lateral epicondyle, proximal ulna -> base of 5th metacarpal (ulnar hand)
