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
