<prompt> All of the following muscles have dual nerve supply, EXCEPT?BrachialisPectineusFlexor digitorum superficialisFlexor digitorum profundus  <response>: Flexor digitorum superficialis muscle primarily produces flexion at the wrist and at the metacarpophalangeal and proximal interphalangeal joints. Innervation is provided by the median nerve C8-T1.The brachialis muscle is supplied by musculocutaneous nerve C5-C6 and radial nerve C7.The femoral nerve L2 and L3 innervates pectineus muscle, with occasional branches from the obturator nerve.The lateral half of the flexor digitorum profundus muscle is innervated by the anterior interosseous nerve from the median nerve C8-T1, and the medial half of the muscle is innervated by the ulnar nerve C8-T1.
