Volar aspect of right hand

Superficial structures of palm, close-up view

The specimen is the same as shown in 101-1. Details of the origin of the palmaris brevis muscle are shown. This muscle arises from transverse fibres which lie deep to the longitudinal fibres of the palmar aponeurosis.

1 .	Palmar aponeurosis (fibrous septa which extended between dermis and palmar aponeurosis remain as ridges on the aponeurosis)
2 .	Proper palmar digital nerves of median nerve
3 .	Transverse fascicle of palmar aponeurosis
4 .	Proper palmar digital nerve of median nerve (to thumb)
5 .	Proper palmar digital artery (to thumb)
6 .	Anastomotic loop between branches of radial and median nerves
7 .	Terminal branch of superficial branch of radial nerve
8 .	Pacinian corpuscles
9 .	Abductor pollicis brevis muscle (covered by thenar fascia)
10 .	Palmar cutaneous branch of median nerve
11 .	Transverse fascicle of palmar aponeurosis (area of origin of palmaris brevis muscle)
12 .	Palmaris brevis muscle
13 .	Cutaneous branches of of ulnar nerve
14 .	Superficial fascia
15 .	Flexor digiti minimi muscle (covered by hypothenar fascia)
16 .	Proper palmar digital nerves of ulnar nerve
17 .	Ligament of digital sheath V
