Question

which muscles are part of the l5 myotome?
hamstring, extensor digitorum longus, extensor hallucis longus
iliacus, psoas, peroneals
tibialis anterior, gastrocnemius, peroneals
quadriceps, tibialis anterior, gastrocnemius

Explanation:

The L5 myotome is associated with muscles that control ankle dorsiflexion, toe extension, and some hip extension. The hamstring (part of hip extension), Extensor Digitorum Longus (toe extension), and Extensor Hallucis Longus (great toe extension) are all innervated by the L5 spinal nerve root, making them part of the L5 myotome. Other options include muscles linked to different myotomes (e.g., iliacus/psoas with L2-L3, gastrocnemius with S1, quadriceps with L3-L4).

Answer:

Hamstring, Extensor Digitorum Longus, Extensor Hallucis Longus
