flexor carpi ulnaris and 2 tendons on ulnar side of the flexor digitorum profundus that are innervated by the ULNAR nerve
37
MEDIAN nerve injury leads to papal benediction sign and ape hand
papal benediction sign keeps ring and pinky finger flexed
38
Thenar eminence
hypothenar eminence mostly by the medial nerve “Ape hand” the Thenar eminence becomes flat and atrophies
39
what is the common head? Medial and lateral epicondyle
The medial epicondyle of the humerus is the common head for the flexors in forearm The lateral epicondyle of the humerus is the common head for the extensors in forearm
40
Medial epicondylitis golfers elbow
inflammation of the elbow from one way motion
41
Lateral epicondylitis tennis elbow
inflammation of the elbow from forward and backward motions
42
Flexor Digitorum Profundus
I: Median and Ulnar n. | palpal benediction sign keeps middle and pointer finger paralyzed by ring and punky can flex
43
Ape hand
median nerve paralyzed causing the thenar area to become stagnant
44
Guyon’s canal
transmits ulnar artery, vein, and nerve | between the two layers of flexor rentinaculum not in the carpal tunnel
45
Superficial radial nerve
goes to skin of thumb side of hand | dorsal side
46
Deep radial nerve
innervates most of muscles on dorsal of forearm
47
Brachioradialis
I: radial nerve before branching to deep/superficial
48
Extensor capri radialis brevis
I: deep radial n
49
Extensor carpi radialis longus
I: radial n before branching
50
Close to elbow the radial nerve divides
superficial and deep
51
Ulnar nerve injury leads to flexion of fingers
extension at metacarpal joints flexion at interfalangial joints CLAW HAND – due to interosseous unique extensor/flexor functionality
52
Interosseous muscles
I: ulnar n. | A: abduction and adduction of digits
53
Mid shaft injury may still have extension of elbow
if above mid shaft then extension of elbow may be compromised as well Wrist drop in both scenarios Radial nerve injury
54
