36
Q

Atrophy of mm indicates a neuropathy of the ___

A

PNS (lower motor neurons)

37
Q

The ring finger sensation is supplied by what two nerves

A

Median and ulnar

38
Q

Median nerve can be. Compressed at the ___ and causes pain numbness and paresthesias that spread downward from the wrist

A

Carpal tunnel

39
