Facial nerve & facial expression (anatomy)

The facial nerve is a bit of a beast, so let's just look at the part of this cranial nerve that innervates the muscles of facial expression. How can you use this anatomy to diagnose upper motor neurone (e.g. stroke) vs lower motor neurone (e.g. Bell's palsy) problems?

THANK YOU, Dr. Sam Webster. The students at SWANSEA University Medical School is lucky to have you.

Best anatomy channel on KZbin and I've seen so many. Keep up the awesome work. Really helping with my understanding. You have a gift for teaching :)

The parotid gland is innervated by the glossopharyngeal nerve (CN 9) not the facial nerve (CN 7)

[@kayshaa]

Facial nerve pierces the parotid gland

[@thobaningomane4653]

Very true. The facial nerve passes through the parotid gland without innervating it.

[@drholiday4147]

In 9:42 he said that

[@lewarzebari2894]

There is sensory and autonomic ... Sensory is by auriculotemporal nerve and greater auricular Parasympathetic is by c9 (from c9 to preganglionic to otic ganglion to post ganglion then to auricutemporal) means auricutemporal and c9 Sympathetic is from superior cervical ganglion

[@gittayusuf2417]

That's what he said ,it just passes through it doesn't innervate it . Watch the video again

[@sthuhnxumalo2450]

The Zebra Bit My Carrot. That is what i use to remember the branches of the facial nerve

[@jaspreetkaur4521]

Thank you so much sir I am a medical student from India . Your videos are really very helpful ,the models you use and the way you explain is really amazing 😊

[@drdoody69]

Parotid Gland: 1- Sensory through the CN V2 (trigeminal - Mandibular). The nerve is Auriculotemporal nerve. 2- Secretomotor (Salivation) is through the postganglionic parasympathetic fibers of CN IX (glossopharyngeal - lesser petrosal nerve from tympanic nerve), which leaves the ganglion in accompany of (same together) as the CN V2 auriculotemporal nerve mentioned above. Is that in simple way terms correct? reminds us of Lacrimal gland - (CN V1 & CN VII)!!

[@natashachihanga108]

People like you in class are awsome

[@Noname00520]

Correction! Sensory CN V2 is Maxillary branch of Trigeminal Nerve

[@raa3385]

You have the coolest anatomy lab I’ve ever seen 😍👍🏼👍🏼👍🏼👍🏼

[@pkalamaris]

As always, an excellent job. My limbic system is engaged at some point in every one of your videos. 😉

[@agustinacaminos1527]

Sam you are amazing! Best teacher ever!!! I'm learning so much, thank youu! :)

[@TheDavveponken]

I realize this is an old video by now but if anyone knows, can these nerves be damaged by pressure from a nearby artery or by stimulants of the central nervous system? I've been having cramps followed by pain in several of these nerves following a treatment with a stimulant drug. The first six months I had lots of tension in the face and a loss of sense of "my brain" and impaired cognitive and emotional as well as sexual functioning.

[@shashibhusan605]

Thanks a lot for enhancing our knowledge on cranial nerve and their root origin representation in the brain,medulla oblongata,pons and other similar nerve travelling systems.Once again thanks to Dr Sam sir.

[@misslorispreschool]

Thank you for the great video! ❤️

[@amirjr178]

Thank you sir , you made me love the anatomy for the first time ! I wish you a happy new year ❤️

Thank you Dr. Webster, i love your videos, it helps me a lot

[@ruslanazhyvtsova8424]

Thank you so much! Ukrainian students from Lviv medical university are delighted with your videos.

[@d3fil4dddsspecz]

Auriculotemporal nerve with the Lesser Petrosal nerve innervate the parotid gland.

[@ehabalshorachi4410]

just another amazing video, thank you !!!

[@malikyasir4714]

Great...never seen such an educational video. all are so boring but this is awesome. Loved it and subscribed it. hope you will keep uploading these kinda videos.

Our demonstrator gave us a good rhyme for the different branches of CNVII To Zanzibar By Motor Car

[@bcr1103]

Exactly....same here RW campus

[@donnavondickersohn1923]

What would happen if someone was born without the main facial nerve branch on one side of their brain? Would there be any function at all on the appropriate side? Will there be minimal movement around the mouth for example the buckle branch?

[@stash_of_g]

love it, love you for making my anatomy absolutely sweet.

[@watcharapornsrisuk9666]

Best channel, love it so much

[@nasrindadras3540]

Great job

[@asmaeboulanouar1322]

Thank you so much teacher !!!!!

[@anikettripathi7991]

Besides anatomy facial nerve is. Components of autonomic nerve systems. And in sanatan philosophy by om chanting and fish mouth practice are for stimulation of automatic system by orbicularis ori facial nerves stimulation.

[@1rrrrrrrrrrr544f]

Wish you were my anatomy teacher 😞

[@bexona5203-jo7iq]

then how/where does hemifacial spasm affect the nerve ?

[@alexandrafisher2380]

Thank you great video

What are the muscles and nerves that innervate the whole face department whether it is glandular part in face region

[@simonjeetsingh1211]

Thanks very much.... I want to ask that do you taught everything which you taught to your students in class if yes its very nice of you and if no please start doing so we can get full knowledge

This is awesome

[@sowmyachowdary4142]

Awesome amazing 👏

[@ibbyibra]

Is that a restoration on your right central incisor? although it could be only some sort of fluorosis. Thanks for the video by the way!!

[@sdj1087]

Sir, the pre ganglionic fibers are from glossopharyngeal nerve and postganglionic fibers run with auriculo temporal nerve to innervate the parotid gland. Am I right sir?

[@SamWebster]

Correct.

[@sdj1087]

@@SamWebster Thank you sir

[@Tony-dk1bp]

Reminds me of "House" without the attitude.

[@muhammadjunaidali9449]

awesome

[@artemouse2007]

decent, thank you

[@hanishshetty8868]

sir I suppose it is auriculo temporal nerve... The nerve supplying parotid gland

[@888167]

it's CN 9 ;)

[@lewarzebari2894]

There is sensory and autonomic ... Sensory is by auriculotemporal nerve and greater auricular Parasympathetic is by c9 (from c9 to preganglionic to otic ganglion to post ganglion then to auricutemporal) means auricutemporal and c9 Sympathetic is from superior cervical ganglion

can you do anatomy of the lips

[@nisharoynisha2915]

I want to make this model could uu please help me and share information

[@iahmad7320]

N.auirculotemporal from the N.mandibular

[@prasenjitraychaudhuri4882]

Your lectures are so good. But this one is all over the place. Kindly focus on the branches and their individual functions and damage to each branch and this will be excellent.

[@888167]

At 23.20 don't you mean "they DO crossover"?

[@HappilyAnonymousGirl]

I couldn’t help but notice your skinless buddy has the same ears and nose as you. Also, I’m curious if the facial muscles can be influenced by forward head posture, causing pressure to be placed on the nerves around the ear.

[@nadimsheikh]

Brilliant and very British

[@AnisurRahman-hf8mw]

Sam u are magnificent ❤️

[@hangvuthi2077]

thank you so much. This video is helpful. ^_^

can nerve face hiling ? please answer me 😭😭😭

[@themostpopularsite]

Just stop for a minute and think about how important the facial nerve is.... Without the facial nerve we would have no emojis, emoticons, smileys... The Internet would be so dry, emotionless, maybe even motionless...

[@omarnw7824]
