Nerven und Blutgefäße der Hand

This video tutorial provides a comprehensive overview of the anatomy of the hand, focusing on the arteries, veins, and nerves. It begins with an introduction to the hand's vascular and nerve structures, followed by a detailed examination of the arterial supply, including the arcus palmaris superficialis and profundus. The tutorial then explores the venous system, highlighting its parallels with the arterial system. Finally, it delves into the nerve supply, discussing the roles of the median and ulnar nerves in sensory and motor functions.

What are the two main arteries that form the arterial arches in the hand?

• Brachial and Axillary arteries

• Carotid and Subclavian arteries

• Ulnar and Radial arteries

• Femoral and Popliteal arteries

Which artery supplies the thumb independently?

• Artery princeps pollicis

• Arcus palmaris profundus

• Arcus palmaris superficialis

• Metacarpal artery

Which artery is not part of the Arcus palmaris superficialis?

• Superficial palmar ramus

• Brachial artery

• Radial artery

• Ulnar artery

From which artery does the Arcus palmaris profundus primarily arise?

• Ulnar artery

• Brachial artery

• Radial artery

• Axillary artery

What is the primary function of the Arcus palmaris profundus?

• Supply the deep structures of the hand

• Supply the superficial palm

• Supply the thumb

• Supply the dorsal side of the hand

Which venous arch opens into the ulnar vein?

• Arcus venosus palmaris superficialis

• Metacarpal vein

• Rete venosum dorsale manus

• Arcus venosus palmaris profundus

What is the primary function of the Rete venosum dorsale manus?

• Supply the thumb

• Supply blood to the fingertips

• Drain venous blood from the hand

• Connect arteries in the hand

Which nerve provides sensory supply to the thumb?

• Axillary nerve

• Median nerve

• Radial nerve

• Ulnar nerve

What is the role of the ramus profundus of the ulnar nerve?

• Motor supply to the forearm

• Motor supply to the hypothenar muscles

• Sensory supply to the index finger

• Sensory supply to the thumb

Which nerve is responsible for the sensory supply of the little finger?

• Median nerve

• Radial nerve

• Ulnar nerve

• Musculocutaneous nerve
