Three muscles that are innervated by specific nerves include the biceps brachii, which is innervated by the musculocutaneous nerve; the quadriceps femoris, innervated by the femoral nerve; and the diaphragm, which is innervated by the phrenic nerve. Each of these nerves plays a crucial role in controlling muscle movement and function.
Femoral nerve
Diaphragm
Yes
The superior oblique muscles
The muscle is innervated by Thoracodorsal nerve, from the posterior cord of brachial plexus.
Posterior Belly of Digastric Muscle (innervated by CN VII) Facial nerve Sternocleidomastoid (innervated by CN XI) Spinal accessory nerve Longissimus Capitis (innervated by dorsal rami of C3-C8 spinal nerves) Splenius Capitis (innervated by dorsal rami of middle cervical spinal nerves)
The sternocleidomastoid muscle (SCM) and the trapezius muscle are innervated by the accessory nerve (CN XI)
The lateral rectus muscle, innervated by the 6th cranial nerve (the Abducens)
The supinator muscle is primarily innervated by the radial nerve, specifically the deep branch of the radial nerve. This nerve provides the necessary motor function to facilitate the supination of the forearm. Additionally, the radial nerve branches may also receive contributions from the posterior interosseous nerve, which is a continuation of the deep branch.
The teres major muscle is innervated by the lower subscapular nerve, which arises from the posterior cord of the brachial plexus (C5-C8).
The flexor muscles, including the biceps brachii which is both a flexor and supinator, are innervated by the musculocutaneous nerve. The supinator muscle, which assists the biceps brachii in supination, is innervated by the deep branch of the radial nerve.
