Arterial Supply of the Hand

This tutorial by Peter from Anatomy Zone explores the arterial supply to the hand, focusing on the radial and ulnar arteries. It covers the superficial and deep palmar arches, detailing their formation and the branches involved. The video also examines the dorsal arterial supply, highlighting the anastomoses between different branches. The tutorial provides a comprehensive overview of how blood is supplied to the hand and wrist, emphasizing the roles of the radial and ulnar arteries.

Which arteries provide the main arterial supply to the hand?

• Radial and ulnar arteries

• Femoral and popliteal arteries

• Brachial and axillary arteries

• Carotid and subclavian arteries

Which artery supplies the lateral half of the index finger?

• Radial artery

• Ulnar artery

• Axillary artery

• Brachial artery

Where is the superficial palmar arch located in relation to the flexor tendons?

• Deep to the flexor tendons

• Superficial to the flexor tendons

• Lateral to the flexor tendons

• Medial to the flexor tendons

What does the ulnar artery primarily supply in the hand?

• Thumb and index finger

• Medial half of the index finger and fingers three, four, and five

• All fingers equally

• Only the thumb

What is the function of the deep palmar branch of the ulnar artery?

• Supplies the thumb

• Forms the superficial palmar arch

• Supplies the dorsal aspect of the hand

• Anastomoses with a branch of the radial artery to form the deep palmar arch
