Neurovasculature of elbow and forearm

This tutorial covers the neurovascular anatomy of the forearm, focusing on the arteries, veins, and nerves. It details the common, anterior, and posterior interosseous arteries, as well as the radial recurrent artery. The tutorial also explains the basilic, cephalic, and median cubital veins, and their roles in venous blood flow. Additionally, it discusses the lateral, medial, and posterior cutaneous nerves, along with the superficial branch of the radial nerve, highlighting their sensory and motor functions.

Which artery is known for running between the radius and ulna?

• Brachial artery

• Radial artery

• Common interosseous artery

• Ulnar artery

What is the function of the radial recurrent artery?

• Forms an anastomosis with the deep brachial artery

• Drains into the axillary vein

• Supplies the hand

• Supplies the dorsal muscles of the forearm

Which artery supplies the elbow joint with blood?

• Anterior interosseous artery

• Posterior interosseous artery

• Radial recurrent artery

• Common interosseous artery

Which vein is commonly used for blood drawing in the forearm?

• Basilic vein

• Radial vein

• Median cubital vein

• Cephalic vein

Where does the basilic vein drain?

• Into the cephalic vein

• Into the axillary vein

• Into the ulnar vein

• Into the radial vein

What is the origin of the lateral cutaneous nerve of the forearm?

• Median nerve

• Musculocutaneous nerve

• Ulnar nerve

• Radial nerve

Which nerve supplies the skin over the lateral half of the forearm's volar surface?

• Lateral cutaneous nerve

• Medial cutaneous nerve

• Superficial branch of the radial nerve

• Posterior cutaneous nerve

From which nerve does the posterior cutaneous nerve of the forearm arise?

• Median nerve

• Musculocutaneous nerve

• Radial nerve

• Ulnar nerve

What is the primary function of the superficial branch of the radial nerve?

• Motor control of the forearm

• Draining blood from the forearm

• Sensory innervation

• Blood supply to the forearm

Which nerve supplies the skin of the radial side of the ball of the thumb?

• Lateral cutaneous nerve

• Posterior cutaneous nerve

• Medial cutaneous nerve

• Superficial branch of the radial nerve
