Question

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

Explanation:

Myotomes are muscle groups innervated by a single spinal nerve root. The L5 myotome is associated with muscles that control ankle dorsiflexion, toe extension, and hip extension. The Hamstring (hip extension), Extensor Digitorum Longus (toe extension), and Extensor Hallucis Longus (great toe extension) are all innervated by the L5 spinal nerve root. Other options include muscles from different myotomes (e.g., Gastrocnemius is S1, Quadriceps is L3-L4, Iliacus/Psoas is L2-L3).

Answer:

Hamstring, Extensor Digitorum Longus, Extensor Hallucis Longus
