Quizplus · Accepted Answer

The ulnar nerve innervates the medial half of the flexor digitorum profundus (FDP), the flexor carpi ulnaris (FCU), the adductor pollicis, and all the small muscles of the hand except the thenar muscles and the lateral two lumbricals. The abductor pollicis brevis (APB) is innervated by the median nerve, not the ulnar nerve, making it the correct choice.
