The abducens nerve (cranial nerve VI) primarily innervates the lateral rectus muscle of the eye. This muscle is responsible for abducting the eyeball, allowing it to move laterally. Dysfunction of the abducens nerve can lead to issues such as strabismus or difficulty in lateral eye movement.
What else can I help you with?
Which muscle is innervated by the phrenic nerve?
Diaphragm
Is hypoglossal nerve an efferent nerve?
Yes, efferent refers to the fact that the nerve carries information from your central nervous system out to a muscle. In this case, the muscle being innervated in the tongue.
What nerves supply the innervation of the bladder and the internal sphincter?
The bladder is innervated by the parasympathetic fibers of the pelvic splanchnic nerves (S2-S4) which stimulate contraction of the detrusor muscle. The internal urethral sphincter is innervated by sympathetic fibers from the hypogastric nerve, which cause it to contract and prevent urine leakage.
What is the Innervation of visceral and parietal pleura?
The visceral pleura is innervated by autonomic nerves that travel with the bronchial blood vessels. The parietal pleura is innervated by somatic nerves, specifically the intercostal nerves and the phrenic nerve.
What is the central innervation of the diaphragm?
The diaphragm is mostly innervated by the phrenic nerve.
Which muscle is innervated by the phrenic nerve?
Diaphragm
Is the orbicularis oculi muscle innervated by the facial nerve?
Yes
What muscle is innervated by the trochlear nerve?
The superior oblique muscles
What three muscles are innervated by nerves?
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.
Which nerve controls the movement of the lattisimus dorsi muscle?
The muscle is innervated by Thoracodorsal nerve, from the posterior cord of brachial plexus.
Muscle inserts into the mastoid process?
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)
Which muscles are affected by the right accessory nerve?
The sternocleidomastoid muscle (SCM) and the trapezius muscle are innervated by the accessory nerve (CN XI)
What abducts the eye?
The lateral rectus muscle, innervated by the 6th cranial nerve (the Abducens)
The supinator muscle is innervated by what nerves?
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.
Which nerve supplies teres major muscle?
The teres major muscle is innervated by the lower subscapular nerve, which arises from the posterior cord of the brachial plexus (C5-C8).
Which adductor muscle is innervated by two nerves?
The adductor magnus muscle is innervated by two nerves: the obturator nerve, which innervates the adductor part, and the tibial part of the sciatic nerve, which innervates the hamstring part. This dual innervation reflects the muscle's complex structure and varied functions in hip adduction and extension.
What nerve causes flexion and supination at the right elbow joint?
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.
