This tutorial covers the neurovascular anatomy of the hand, focusing on the arterial, venous, and nervous systems. It explains the superficial and deep palmar arches, the dorsal carpal arch, and the principal artery of the thumb. The venous system is compared to the arterial system, highlighting the superficial and deep palmar venous arches and the dorsal venous network. The tutorial also details the nerves of the hand, including the median, ulnar, and radial nerves, and their branches.

Which of the following arteries is NOT part of the palmar arterial network?

• Dorsal carpal arch

• Deep palmar arch

• Common palmar digital artery

• Superficial palmar arch

What forms the superficial palmar arch?

• Radial artery and ulnar artery

• Dorsal carpal branch of the radial artery

• Deep palmar branch of the ulnar artery

• Ulnar artery and superficial palmar branch of the radial artery

Which artery supplies the thumb?

• Proper palmar digital artery

• Common palmar digital artery

• Dorsal digital artery

• Principal artery of the thumb

What is the primary function of the deep palmar arch?

• Supply blood to the thumb

• Drain blood into the radial vein

• Form an anastomosis with the superficial palmar arch

• Supply blood to the dorsal side of the hand

Which artery is responsible for supplying the dorsal side of the hand?

• Dorsal carpal arch

• Deep palmar arch

• Common palmar digital artery

• Superficial palmar arch

Which veins are part of the dorsal venous network?

• Superficial palmar venous arch

• Dorsal metacarpal veins

• Common palmar digital veins

• Palmar metacarpal veins

What is the role of the superficial branch of the ulnar nerve?

• Provide sensation to the thumb

• Supply the skin on the ulnar side of the hand

• Innervate the hypothenar muscles

• Innervate the interossei muscles

Which nerve supplies the lateral 3 1/2 digits of the hand?

• Dorsal branch of the ulnar nerve

• Ulnar nerve

• Median nerve

• Radial nerve

What is the primary function of the deep branch of the ulnar nerve?

• Innervate the interossei muscles

• Supply the skin on the radial side of the hand

• Innervate the hypothenar muscles

• Provide sensation to the thumb

Which nerve is responsible for the sensation of the medial 1 1/2 digits?

• Radial nerve

• Superficial branch of the ulnar nerve

• Median nerve

• Deep branch of the ulnar nerve
