Hand anatomical enlargement simulator

■  The simulator is magnified twice and can be divided into three parts. The skin and appendages are peeled off, and a portion of the palmaris longus tendon is removed to display the abductor pollicis brevis, flexor pollicis brevis, flexor pollicis, flexor pollicis longus tendon, superficial flexor digitorum tendon, superficial palmar arch, palmar common nerve, median nerve, and palmar intrinsic arterial nerve. The superficial flexor digitorum tendon is removed from the palm, and structures such as the deep branch of the palmar arch, deep branch of the ulnar nerve, and partial metacarpal bone are visible. A transverse section is made at the metacarpal bone position to observe its cross-sectional structure. Part of the deep digitorum tendon is removed from the back of the hand to display the dorsal palmar artery and extensor muscle support band.
