Learn the 12 Cranial Nerves with mnemonics! (NEW | EASY) - Anatomy

The Cranial Nerves quick and easy!: Learn each cranial nerve I-XII (1-12) with mnemonics and hints!

✅ Overview

Set of 12 paired nerves that arise directly from our brain! Well the first two arise from the cerebrum & rest of them from the brainstem.

*Midbrain - trochlear nerve CN 4 comes from the posterior side of the midbrain and is the longest intracranial length of all the CNs.
*Midbrain-pontine junction - oculomotor nerve CN 3
*Pons - Trigeminal nerve CN 5
*Pontine-medulla junction - abducens CN 6, facial CN 7, vestibulocochlear CN 8 nerves.
*Medulla oblongata - Posterior to the olive: glossopharyngeal CN 9, vagus CN 10, accessory CN 11 nerves. Anterior to the olive: hypoglossal nerve CN 12

Cranial nerve tests will help you assess the neuro status of your patient. Each test is designed to target a specific cranial nerve (or group of nerves). Here are the twelve cranial nerves assessed in this video:

The 12 Cranial Nerves all have ways to remember them by. Here we speak about their origin, function, fiber and tips to remember them by.

✅ Cranial Nerves

Cranial Nerve I (1): Olfactory Nerve
*Sensory: nose & smell
Cranial Nerve II (2): Optic Nerve
*Sensory: eye sight
Cranial Nerve III (3): Oculomotor Nerve
*Motor: all eye muscles except those supplied by CN 4 and 6 (SO4 LR6 Rest 3)
Cranial Nerve IV (4): Trochlear Nerve
*Motor: eye movement from the superior oblique muscle
Cranial Nerve V (5): Trigeminal Nerve
*Sensory: face, sinuses, teeth
*Motor: jaw muscles
Cranial Nerve VI (6): Abducens Nerve
*Motor: eye movement from the lateral rectus muscle
Cranial Nerve VII (7): Facial Nerve
*Motor: submaxillary & sublingual gland, muscles of the face
*Sensory: front of tongue and soft palate
Cranial Nerve VIII (8): Vestibulocochlear Nerve
*Sensory: hearing & balance
Cranial Nerve IX (9): Glossopharyngeal Nerve
*Motor: swelling with pharyngeal musculature
*Sensory: taste & sensation on back part of tongue (post. 1/3rd), tonsil, & pharynx
Cranial Nerve X (10): Vagus Nerve
*Motor: heart, lungs, bronchi & GI tract
*Sensory: heart, lungs, bronchi, trachea, larynx, pharynx, GI tract & external ear.
Cranial Nerve XI (11): Accessory Nerve
*Motor: for trapezius & sternocleidomastoid muscles.
Cranial Nerve XII (12): Hypoglossal Nerve
*Motor: all muscles of the tongue, except the palatoglossus.

This is the cutest, cleanest, most universally applicable version I've ever seen =o

[sheenashearer]

This video deserves WAY more attention than it has received!

[PrincessIGM]

I had to say thank you so much for this video!!! Anatomy test in less than 2 hours and this is the only video I have watched in the last 48 hours that is actually clicking for me!!(which was a LOTTTT of videos) thank you thank you!!!❤❤

[ngoclinhnguyen]

Thank you for helping me to learn anatomy quickly and easily!^^

Olfactory - smelling sensations, sends
Optic nerves- Visual information to the brain
Occulomotor- movement of the eye
Trochlear- rotation of the eye ball
Abducens- controls the lateral recuts
Trigeminal- facial sensations
Facial nerve - facial expressions
Vestibulocolear- supplies for equilibrium
Glossopharyngeal- triggers gag reflex
Vegas Nerve- slows heart rate
Spinal Accessory- supplies for movement of certain muscles
Hypoglossal- allows you to talk and move tongue

U are a hero perfect timing in 3 days I have an exam about cranial nerves.

[mdamanali]

Upload more anatomy videos
Your videos are very helpful

[harnoord]

Too good 💯made me learn it in minutes 💯👏🏻

[eduguide]

Pls do more videos very simple and understanding and interesting

[mamdaero_]

Thank you so much. Please make more videos like this. It's super helpful and easy to understand! Thanks again.

[shivanigalande]

Why are u not making more video, plz keep doing ur work

[adityabhardwaj]

Just love your work guys😘❤️... Keep it up. 👍

[hermionegracien]

Is there a website where we can get the diagrams or is there an ebook?

[Continuevideos]

Please make easy medical tricks every day 1 video and fix time share in a day

3:48 I think it is wrong, the correct one is SUPERIOR OBLIQUE MUSCLE- MEDIALLY rotates the eyeball. Inferior oblique muscle laterally rotates the eyeball

[MarsellaFyngold]

You made a small error:
10:50 the SCM is the sternocleidomastoid vs sternoclediomastoid -- Just a smoll transposition of where the "i" and the "d" go but otherwise all very good info and well put together =3
