A 6-Year-Old Boy, Running Along a Concrete Path with a Glass

A 6-year-old boy, running along a concrete path with a glass jam jar in his hand, slipped and fell. The glass from the broken jar pierced the skin on the front of his left wrist. On examination a small wound was present on the front of the left wrist and the palmaris longus tendon had been severed. The thumb was laterally rotated and adducted, and the boy was unable to oppose his thumb to the other fingers. There was loss of skin sensation over the lateral half of the palm and the palmar aspect of the lateral three and a half fingers.
-The following facts concerning this patient are correct except which?

A) Sensory loss of the distal part of the dorsal surfaces of the lateral three and a half fingers was experienced.
B) The median nerve lies superficial to the palmaris longus proximal to the flexor retinaculum and was severed by the piece of glass.
C) The median nerve lies in the interval between the tendons of the flexor digitorum superficialis and the flexor carpi radialis muscles just proximal to the wrist joint.
D) Adduction of the thumb was produced by the contraction of the adductor pollicis muscle, which is supplied by the ulnar nerve.
E) The palmar cutaneous branch of the median nerve had been severed.
