Which nerve innervates abductor digiti minimi?

• A. Deep Fibular Nerve
• B. Medial Plantar Nerve
• C. Tibial Nerve
• D. Lateral Plantar Nerve

Answer: (D)

The nerve that innervates the abductor digiti minimi in the foot is the lateral plantar nerve. This muscle is one of the intrinsic plantar muscles, and the tibial nerve branches in the sole into the medial and lateral plantar nerves. The medial plantar nerve supplies muscles like abductor hallucis and flexor digitorum brevis, while the lateral plantar nerve handles the rest of the intrinsic plantar muscles, including abductor digiti minimi, quadratus plantae, adductor hallucis, flexor digiti minimi brevis, and the plantar and dorsal interossei. The deep fibular nerve does not reach the plantar muscles, and the tibial nerve is the parent nerve whose lateral plantar branch delivers this specific innervation.
