91

muscles of the superficial extensors group

brachioradialis
extensor carpi radialis longus
extensor carpi radialis brevis
extensor digitorum
extensor digiti minimi
extensor carpi lunaris

92

proximal attachment of brachioradialis

proximal supraepicondylar ridge of humerus

93

distal attachment of brachioradialis

distal radius
proximal to styloid process

94

actions of brachioradialis

flexes forearm why it is pronated

95

innervation of brachioradialis

radial nerve

96

proximal attachment of extensor carpi radialis longus

lateral supracondular ridge of humerus

about same as brachioradialis

97

distal attachment of extensor carpi radialis longus

dorsal aspect of base of 2nd metacarpal

98

actions of extensor carpi radialis longus

extends and abducts hand at wrist

99

innervation of extensor carpi radialis longus

radial nerve

100

proximal attachment of extensor carpi radialis brevis

lateral epicondyle of humerus

101

distal attachment of extensor carpi radialis brevis

dorsal aspect base of 3rd metacarpal

102

innervation of extensor carpi radialis brevis

deep branch of radial nerve

103

proximal attachment of extensor digitorum

lateral epicondyle of humerus

104

distal attachment of extensor digitorum

extensor expansions of medial 4 fingers

105

actions of extensor digitorum

extends medial 4 fingers at metacarpophalangeal joints and somewhat at interphalangela joints

106

innervation of extensor digitorum

posterior interosseous nerve

107

proximal attachment of extensor digiti minimi

lateral epicondyle of humerus

108

distal attachment of extensor digiti minimi

extensor expansion of 5th finger

109

actions of extensor digiti minimi

extends 5th finger at metacarpophalangeal joint and secondarily at interphalangeal joints

110

innervation of extensor digiti minimi

posterior interosseous

111

proximal attachment of extensor carpi lunaris

lateral epicondyle and posterior border of ulna

112

distal attachment of extensor carpi lunaris

dorsal aspect of base for 5th metacarpal

113

innervation of extensor carpi lunaris

posterior interosseous nerve

114

actions of extensor carpi lunaris

extends and adducts hand at wrist

115

deep extensors

supinator
extensor indicis
abductor pollicis longus
extensor pollicis longus
extensor pollicis brevis

116

proximal attachment of supinator

lateral epicondyle of humerus

radial collateral and angular ligaments

ulnar crest

117

distal attachment of supinator

proximal radius (nearly all surfaces)

118

actions of supinator

supinates forearm

bringing radius back to anatomical position

119

innervation of of supinator

deep branch of radial nerve

120

proximal attachment of extensor indicis

posterior surface of distal ulna and interosseous membrane
