How do you test the cranial nerve x11?

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 best way to test cranial nerve VII?

Ask the patient to smile, show their teeth and close the eyes tightly. Try to open the lids to see if eye lid closure strength is equal. Ask patient to wrinkle forehead. Observe for symmetry of facial movement.

How do you test for CN vagus?

The vagus nerve provides motor supply to the pharynx. To test the vagus nerve, ask the patient to say “AH,” which will cause the pharynx to elevate, and observe the position of the uvula. When the palatal muscles works properly, the “AH,” sound should be clear and the uvula should not move to one side.

What is cranial nerve XI?

Introduction. The accessory spinal nerve or XI cranial nerve is essential for neck and shoulder movement, the intrinsic musculature of the larynx, and the sensitive afferences of the trapezius and sternocleidomastoid musculature.

How should nurse assess cranial nerves III IV and VI?

Cranial Nerve III, IV, and VI – Oculomotor, Trochlear, Abducens

  1. Test eye movement by using a penlight. Stand 1 foot in front of the patient and ask them to follow the direction of the penlight with only their eyes.
  2. Test bilateral pupils to ensure they are equally round and reactive to light and accommodation .

Which CN is tested with tongue protrusion?

The hypoglossal nerve controls the intrinsic musculature of the tongue and is evaluated by having the patient “stick out their tongue” and move it side to side. Normally, the tongue will be protruded from the mouth and remain midline.

How do you perform a gag reflex test?

Testing the gag reflex can help assess damage to CN IX and CN X. To test the gag reflex, you gently touch first one and then the other palatal arch with a cotton swab or tongue blade, waiting each time for gagging. If the glossopharyngeal nerve (IX) is damaged on one side, there will be no response when touched.

What is CN VII?

The facial nerve is the seventh cranial nerve (CN VII). It arises from the brain stem and extends posteriorly to the abducens nerve and anteriorly to the vestibulocochlear nerve.

What does the 11th cranial nerve do?

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 is cranial nerve XII?

The Hypoglossal Nerve is the 12th Cranial Nerve (Cranial Nerve XII). It is mainly an efferent nerve for the tongue musculature. The nerve originates from the medulla and travels caudally and dorsally to the tongue.
