What is the nerve supply of the muscles of facial expression?
The facial muscles are innervated by facial nerve (cranial nerve VII). In contrast, the nearby masticatory muscles are innervated by the mandibular nerve, a branch of thetrigeminal nerve (V).
Flexor muscles in the anterior arm are innervated by what nerve?
The musculocutaneous nerve
What is the major nerves serve the most anterior forearm muscle?
The median nerve supplies most of the flexor muscles of the human forearm, and some hand muscles. The ulnar nerve also supplies two flexor muscles, and most of the remaining hand muscles that the median nerve does not cover.
What muscle is innervated by the trochlear nerve?
The superior oblique muscles
Ulnar nerve test for loss of function?
Ulnar nerve typically supplies the intrinsic muscles of the hand. Hence the tests for ulnar nerve are based on the functions performed by these muscles. The intrinsic muscles or interossei are concerned with gripping function of the fingers. So things like holding a card or cigarette between 2 fingers is with the help of these muscles. A generalized loss of coordination of hands causing clumsy hands is often seen with ulnar nerve diseases or palsy. Tests like, froment's sign, card test, and so on, are used for evaluation of ulnar nerve injury.
What muscles are mimetic muscles?
They are facial muscles innervated by the facial nerve that, among other things, control facial expression.
What major nerves serve the medial side of the hand?
You have three nerves, which supply your forearm. Radial, ulnar and median nerve. Out of these three nerves, median nerve is the main nerve to supply forearm muscles and some of the hand muscles.
Which of the following muscles is innervated by the axillary nerve?
deltoid and teres minor
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 2 muscles are innervated by cranial nerve XII besides the 4 intrinsic lingual muscles and the 4 extrinsic lingual muscles?
Geniohyoid & Thyrohyoid as the Hypoglossal nerve is joined by fibers from C1 which supply them
What is the medical condition cubital tunnel syndrome associated with nerve compression?
This syndrome results from pressure that compresses the ulnar nerve. The ulnar nerve is one of the main nerves of the hand, which connects the muscles of the forearm and hand with the spinal cord.
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.
