Anatomy of the Wrist and Hand Quiz

There are 8 carpal bones in the wrist.

Radius is not a carpal bone.

The scaphoid bone is most commonly fractured.

Carpal tunnel syndrome results from compression of the median nerve.

The median nerve provides sensory innervation to the palmar aspect of the thumb, index, middle finger, and lateral half of the ring finger.

Metacarpals are the anatomical name for the thumb bone.

The flexor tendon sheath is responsible for the 'snapping' sensation in trigger finger condition.

De Quervain's Tenosynovitis involves the abductor pollicis longus and extensor pollicis brevis tendons.

The primary function of the palmar aponeurosis is to protect the underlying tendons and nerves.

The anatomical snuffbox is bordered by the extensor pollicis brevis and abductor pollicis longus tendons.

The TFCC is located between the radius and ulna bones.

The ulnar nerve innervates the adductor pollicis muscle.

Dupuytren's contracture primarily affects the palm and flexor tendons of the hand.

The triangular fibrocartilage complex is crucial for stabilizing the distal radioulnar joint.

The hook of the hamate bone is a common site for fractures.
