The branches of median nerve are presented in

Table A1.3.

Ulnar nerve is named so as it runs along the medial or

ulnar side of the upper limb.

Root aalue:Yentral rami of C8 and T1. It also gets fibres

of C7 from the lateral root of median nerve (see Fig. 4.14).

. Two digital branches to lateral
and medial sides of thumb
. One to lateral side of index finger
. Two to adjacent sides of index
and middle fingers
. Two to adjacent sides of middle
and ring fingers. These branches
also supply dorsal aspects of
distal phalanges of lateral three
and a half digits
Give vascular and articular
branches to joints of hand
