How do nurses remember cranial nerves?

Mnemonic for Order of Cranial Nerves

1. Old: Olfactory.
2. Operators: Optic.
3. Occasionally: Oculomotor.
4. Troubleshoot: Trochlear.
5. Tricky: Trigeminal.
6. Abducted: Abducens.
7. Family: Facial.
8. Veterans: Vestibulocochlear.

How do you examine the cranial nerves?

CN IX and CN X nerves can be assessed together:

1. Ask the patient to cough (assessing CN X)
2. Ask the patient to open the mouth wide and say ‘ah’, using a tongue depressor to visual the palate and posterior pharyngeal wall (assessing CN IX and X) The soft palate should move upwards centrally.

What cranial nerves are sensory only?

Cranial nerves I, II, and VIII are pure sensory nerves. Cranial nerves III, IV, VI, XI, and XII are pure motor nerves. Cranial nerves V, VII, IX, and X are mixed sensory and motor nerves. The olfactory nerve (CN I) contains special sensory neurons concerned with smell.

What are the 10 cranial nerves?

olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, spinal accessory, hypoglossal.

Why do we test cranial nerves?

CRANIAL NERVES The cranial nerve examination may reveal signs of sensory or motor dysfunction that could affect gait. Decreased visual acuity, visual field deficits, or visual neglect may cause a patient to adopt a cautious gait pattern and may contribute to falls.

How do you test Abducens?

Assessment. The abducens nerve is examined in conjunction with the oculomotor and trochlear nerves by testing the movements of the eye. The patient is asked to follow a point with their eyes (commonly the tip of a pen) without moving their head.

Which is the shortest cranial nerve?

The trochlear nerve
The trochlear nerve, while the smallest of the cranial nerves, has the longest intracranial course as it is the only nerve to have a dorsal exit from the brainstem. It originates in the midbrain and extends laterally and anteriorly to the superior oblique muscle.

How to conduct a cranial nerve examination?

• Ask patient to turn head to one side and push against examiners hand or ask to flex head against resistance, palpate and evaluate strength of sternocleidomastoid muscle. • Evaluate both right and left side, compare for symmetry. CRANIAL NERVES 39 40.

How to test CN 12?

Genioglossus- Draw the tongue forward from the root

Hyoglossus- Retracts the tongue and depresses its side

Styloglossus- Draws the tongue upward

Intrinsic muscles (superior/inferior longitudinales,transversus,verticalis)- Changes the shape of the tongue such as shortening,narrowing,curving the tongue.[1]

What cranial nerve do you use to slow the heart?

Olfactory nerve — It controls your sense of smell.

Optic nerve — It carries visual information from your retina to your brain.

Oculomotor nerve — It controls most of your eye movements along with the way your pupil constricts and the ability to keep your eyelid open.

How does a nurse assess cranial nerve function?

assessment technique. Motor: Ask patient to frown, smile, and wrinkle brow. Inability or asymmetrical facial expression is positive for CN VII lesion. Cranial Nerve VIII (Vestibulocochlear Nerve): Sensory for hearing, motor for balance Vestibular branch (balance): Ask patient to march in place (Mittlemeyer Marching) with eyes closed.
