Which is a function of the accessory XI nerve?

This nerve supplies the sternocleidomastoid and trapezius muscles, which have the following functions: Rotation of head away from the side of the contracting sternocleidomastoid muscle. Tilting of the head toward the contracting sternocleidomastoid muscle. Flexion of the neck by both sternocleidomastoid muscles.

What does the 11th cranial nerve control?

The accessory nerve is the eleventh paired cranial nerve. It has a purely somatic motor function, innervating the sternocleidomastoid and trapezius muscles.

What nerve controls gallbladder?

Innervation. The gallbladder receives parasympathetic, sympathetic and sensory innervation. The coeliac plexus carries sympathetic and sensory fibres, while the vagus nerve delivers parasympathetic innervation.

What does cranial nerve 11 assess?

11th Cranial nerve The 11th (spinal accessory) cranial nerve is evaluated by testing the muscles it supplies: For the sternocleidomastoid, the patient is asked to turn the head against resistance supplied by the examiner’s hand while the examiner palpates the active muscle (opposite the turned head).

What is the main function of the hypoglossal nerve?

The hypoglossal nerve enables tongue movement. It controls the hyoglossus, intrinsic, genioglossus and styloglossus muscles. These muscles help you speak, swallow and move substances around in your mouth.

Can gallbladder affect nerves?

When your gallbladder is inflamed and swollen, it irritates your phrenic nerve. Your phrenic nerve stretches from the abdomen, through the chest, and into your neck. Each time you eat a fatty meal, it aggravates the nerve and causes referred pain in your right shoulder blade.

Why is cranial nerve assessment important?

The cranial nerve examination is important for determining symmetry in general. Asymmetrical findings indicate a pathological process. The eye examination is the most important part of the cranial nerve examination.

Is the cranial nerve part of the vagus nerve?

Accessory Nerve Cranial Nerve 11. Contents. Description. The Spinal Accessory Nerve (SAN) or Cranial Nerve 11 is termed a cranial nerve as it was originally believed to originate in the brain. It has both a cranial and a spinal part, though debate still rages regarding if the cranial part is really a part of the SAN or part of the vagus nerve.

Where does the nerve supply the gallbladder come from?

Similalrly the foregut organs arise from the chest endoderm/mesoderm and so innervation is from the lower thoracic region . The somatic nerves of the gallbladder are from intercostal nerves T8, T9, and T10 spinal segments which supply the parietal peritoneum.

Where does the cranial nerve 11 originate from?

The Spinal Accessory Nerve (SAN) or Cranial Nerve 11 is termed a cranial nerve as it was originally believed to originate in the brain.

Which is part of the cranial nerve supplies innervation?

The cranial part , along with the cranial nerves 9 and 10, supplies innervation to the soft palate, larynx and pharynx. The spinal part supplies innervation to the Sternocleidomastoid and Trapezius muscles. The spinal part on the SAN arises from C1- C5/6 nerve roots.

Which is a function of the accessory XI nerve? This nerve supplies the sternocleidomastoid and trapezius muscles, which have the following functions: Rotation of head away from the side of the contracting sternocleidomastoid muscle. Tilting of the head toward the contracting sternocleidomastoid muscle. Flexion of the neck by both sternocleidomastoid muscles. What does the 11th…
