Question

Which nerve is responsible for the sensation and movement of the ulnar side of the hand?

A) Radial nerve
B) Ulnar nerve
C) Median nerve
D) Axillary nerve

Answer 1

The ulnar nerve is responsible for the sensation and movement of the ulnar side of the hand. It is closely related to the ulna bone in the forearm and controls specific fingers and wrist flexors.

Step-by-step explanation:

The nerve responsible for the sensation and movement of the ulnar side of the hand is the ulnar nerve. The ulnar nerve is situated close to the ulna bone, which is located on the medial side of the forearm. It is the systemic nerve of the arm that controls the sensation and movement of the areas associated with the ulnar side. This includes parts of the hand and forearm such as the little finger and adjacent half of the ring finger and contributes to the control of wrist flexors, which originate from the medial epicondyle of the humerus.
