Question 1

Muscles which produce ? In relation to anterior or posterior division of anterior primary rami

Answer 1

Muscles which produce:

Flexion, addiction and internal rotation, are usually innervated by nerves derived from anterior divisions of anterior primary rami in a nerve plexus

extension abduction or internal rotation usually innervated by posterior divisions of anterior primary rami in nerve plexus
