Which cranial nerve controls the trapezius muscle?

Which cranial nerve controls the trapezius muscle?

the XI nerve
The muscles innervated directly by the XI nerve are the trapezius and the sternocleidomastoid, in addition to the laryngeal musculature (in collaboration with the vagus nerve), such as the palatal, pharyngeal, laryngeal muscles.

Does the accessory nerve innervate the trapezius?

The spinal accessory nerve is a purely motor entity. It innervates both the trapezius and the sternocleidomastoid muscles.

What does thoracodorsal nerve supply?

The thoracodorsal nerve carries solely motor fibers. Its main function is to innervate the latissimus dorsi muscle. When it reaches the muscle, the thoracodorsal nerve gives off several small terminal branches that reach the margins of the muscle and supply the whole muscle.

What does C1 and C2 innervate?

They stimulate muscle movement in your neck, shoulder, arm and hand, and provide sensation. Cervical nerves C1, C2 and C3 control your forward, backward and side head and neck movements. The C2 nerve provides sensation to the upper area of your head; C3 gives sensation to the side of your face and back of your head.

What muscles are innervated by C2 C3?

C1-C2: Rectus capitis anterior and lateralis. C1-C3: Longus capitis. C2-C3: Contributions to the prevertebral muscles and sternocleidomastoid….It gives off four muscular branches:

• Superior belly of the omohyoid muscle.
• Inferior belly of omohyoid muscle.
• Sternohyoid.
• Sternothyroid.

Which of the following nerves Innervates the trapezius and sternocleidomastoid muscle and should be identified and preserved when performing a radical neck dissection?

The spinal accessory nerve
The spinal accessory nerve (XIth crani- al) travels from the skull base to innervate the SCM and the trapezius muscle, usually above the level of the carotid bifurcation below the digas- tric muscle.

Which cranial nerve Innervates and controls the sternocleidomastoid muscle?

The accessory nerve, also known as the eleventh cranial nerve, cranial nerve XI, or simply CN XI, is a cranial nerve that supplies the sternocleidomastoid and trapezius muscles.

Which muscles is innervated by thoracodorsal nerve?

The thoracodorsal nerve is a pure motor nerve that innervates the latissimus dorsi muscle. The latissimus dorsi muscle is a large, fan-shaped muscle that originates from the spinous processes of T7 to L5, the thoracolumbar fascia, and iliac crest.

What does hypoglossal nerve innervate?

The hypoglossal nerve is mainly a somatic efferent (motor) nerve to innervate the tongue musculature. The nerve also contains some sympathetic postganglionic fibers from the cervical ganglia, which innervates tongue vessels and some small glands in the oral mucosa.
