Muscles & Movements
This thenar muscle is responsible for thumb opposition.
What is the opponens pollicis?
The annular ligament stabilizes this joint.
What is the proximal radioulnar joint?
This nerve innervates most of the anterior forearm and thenar muscles.
What is the median nerve?
This artery continues from the brachial artery and runs along the lateral side of the forearm.
What is the radial artery?

What is the median nerve?
This muscle is responsible for extending the fingers at the MCP joints.
What is the extensor digitorum?
This carpal bone articulates with the base of the second and third metacarpals.
What is the capitate?
This nerve runs in the spiral groove of the humerus.
What is the radial nerve?
This deep vein accompanies the brachial artery.
What is the brachial vein?
This carpal bone is the most commonly fractured, often due to a fall on an outstretched hand, and its poor blood supply makes it prone to avascular necrosis.
What is the scaphoid?
This deep muscle flexes the distal interphalangeal joints of the fingers.
What is the flexor digitorum profundus?

What is the ulna?
The ulnar nerve arises from this cord of the brachial plexus.
What is the medial cord?
This superficial vein runs along the lateral side of the forearm and arm, often used for IV access.
What is the cephalic vein?
This condition involves inflammation of the lateral epicondyle due to repetitive wrist extension.
What is tennis elbow?
The palmar interossei muscles perform this movement of the fingers.
What is adduction?
The head of the radius articulates with this part of the humerus.
What is the capitulum?
The five terminal branches of the brachial plexus are…
What are the musculocutaneous, axillary, radial, median, and ulnar nerves?
The radial and ulnar arteries form these two arterial arches in the hand.
What are the superficial and deep palmar arches?
The Allen’s test is used to assess the blood supply to the hand by checking these two arteries.
What are the radial and ulnar arteries?
This small muscle of the thumb, is innervated by the ulnar nerve, unlike the others.
What is the adductor pollicis?
This joint is a saddle joint allowing for opposition.
What is the first carpometacarpal joint?
This nerve innervates the skin over the lateral forearm and is a continuation of the musculocutaneous nerve.
What is the lateral cutaneous nerve of the forearm?
This artery passes through the anatomical snuffbox before entering the hand.
What is the radial artery?
A fracture of the hook of hamate may injure this nerve.
What is the ulnar nerve?
