hey everyone it's Sarah with register nurse rn.com and in this video we're going to go over a teaching series specifically the cranial nerv in this video I'm going to cover the location of the nerves their function and give you two pneumonics to help you remember the order of the cranial nerves and if they're sensing if they're motor or if they're both and then afterwards be sure to go to my website register nurse.com there should be a link that pops up and take the quiz to test your knowledge on this material because if you're in anatomy or another Health rated class that requires you to know these cranial nerves that quiz will help you prepare for your exam so let's get started over all the 12 cranial nerves and where they're located at in the brain and their function cranial nerve number one is called the Ola Factory nerve and it is this pink area right here at the top and it is responsible for smell how you can remember this think of a stinky Factory that maybe live around one and it just stinks outside and just remember from the word Factory it's responsible for smell then cranial nerve number two is called the optic nerve and it is this green area right here and this area is responsible for Sight optic is another word for your eyes and so remember optic eyes and that's responsible for Sight then cranial nerve number three is called the ocular motor and this is this little pink area right here right below the optic nerve area and it is responsible for moving your eyelids your eyeballs and adjust the pupils and the lenses of your eye now let's move down to cranial nerve number four this is called the tro nerve and it is this little purple area right here on these two sides and this area is responsible for moving your eyeballs then over here cranial nerve number five is called the trigeminal nerve and this is the largest nerve out of all these cranial nerves and it is responsible for moving your facial muscles so it allows you to chew and for and to form facial expressions cranial nerve number six is the abducens and it is this little pink area right in here and it is also responsible for moving your eyeballs just like the tular cranial nerve number seven is the facial nerve and notice in this area right here you have a lot of nerves that run in together a good way to remember that is how they're stacked together it's going to be like seven cranial nerve eight cranial nerve 9 10 so whenever you're trying to fill this out in a diagram remember that these nerves are going in chronological order so your facial nerve produces tears it produces your allows you to taste a saliva production and helps you form facial expressions then cranial ner nerve number eight is called the vestibular cular and it is located up here in this area it's the little brown sections and this is responsible for auditory which is hearing remember cular a lot of people get cular implants so they can hear better so that's how you can remember the function of this one cranial nerve number nine is called the gloss glosso fenil and it is this little green area located below the vestibular cular and it's responsible for swallowing and for saliva protection and taste as well now let's go down to cranial nerve number 10 this is our Vegas nerve and it is this pink area right here and it is responsible it controls your peripheral nervous system which is the smooth muscle of the GI tract which allows you to trct food and it relaxes so that controls that area then we have accessory muscle I mean cranial nerve number 11 it's called the accessory and it is this area located right here in the orangish brown area and it is responsible for moving your head and your shoulders and allows for swallowing then we have cranial nerve number 12 which is the last one it's called the hypoglossal and this is responsible for moving your tongue and allows you to formulate speech and swallowing and this area right here is this little purple area right here that sets on top of the stem so that is your tongue remember tongue um the premedical terminology term for that is glossal so anything anytime you see that glossal that means tongue so it allows again for the speech and for swallowing and remember with glosso and Jill that also allowed for swallowing taste and um uh saliva production and that has to do with the tongue so try to remember those that way now let's go over the pneumonic to help you remember the order of these and then another pneumonic to help you remember if it's sensing motor or both okay this first pneumonic we're going to go over is going to allow you to remember the order of the cranial nerve so get down a piece of paper and write it down so you'll remember it I actually me and my husband collaborated together and made this pneumonic up ourselves there's a lot of other pneumonics you can use on the internet I like to use something that makes sense to me and there were some things on there about Olympus and Germany and everything like that and it just didn't make sense to me so we develop this one maybe it'll make sense for you so this is how this one's set up how it works it's like an acrostic and the first two letters of some of these words are going to match up to the cranial nerves up here and let me show you how it works okay the acrostic says old operators occasionally troubleshoot tricky abducted family veterans Galloping Bently across history so how you remember this phrase and how you can remember the order of the nerves is look at old old o l d the first two letters of old match olfactory which is spelled o l so you know the first nerve is olfactory next operators o op same as optic which is cranial nerve 2 op and optic remember that so we got olfactory and optic then we have occasionally OC matches with cranial nerve number two three which is ocular motor troubleshoot T matches with tular which is trro because it gets really confusing through those other pneumonics because I think one was like o o and it's like well o o but which O's are they and I think this pneumonic just helps you a little bit better because it tells you the first two letters of what those specific cranial nerves will be so let's keep going tricky the TR goes for trigeminal then you have abducted which goes for cranial nerve number six which is abducens abducted abducens you remember that and then family for facial Veterans for vestibuloocular and then G alapine we just put that one for G because it's the only G1 so you should know that it's glossop far and gel valant is for Vegas which VA across for accessory the AC and then history for your last one which is hypo gloss seal so I think that pneumonic will help you remember the order of it I like how the first two letters help me remember all those o cranial nerves now let's go over the second acrostic to help you remember if these are sensory or motor or both on these cranial nerves okay for our next acrostic it says some say merry money but my brother says big brains matter more so the key with this is that you want to look at the first letter of these words the s's mean sensory the M's mean motor and the B's mean both so let's go over it some this is referring to cranial nerve number one and it is a sensing nerve say the S is referring to sensing for cranial nerve number two it's a sensing nerve as well Mary M for motor cranial nerve number three is a motor nerve money m is a motor nerve and it's cranial nerve number four but is for both and that's for cranial nerve number five it's both a sensing and a motor Mary for cranial nerve number six and it is for um it's a motor as well and then you have brother and it's cranial nerve number seven and it's for both then you have SS s that is for cranial nerve number eight and it's sensing um cranial nerve number nine the word Big B it's both cranial nerve number 10 B it is is both it's both sine and motor cranial nerve number 11 is an m so it's a motor nerve and cranial nerve number 12 the last one is a motor nerve as well so I thought that this was a great pneumonic that um someone had developed to help you remember those because those are really asked on tests um it'll for instance say is the optic nerve a sensing motor or both or a true or false or something like that so that is just a great acrostic to help you remember that so that is an over review of the cranial nerves now go to my website register nures rn.com and take the quiz and see how well you grasp this material and thank you so much for watching and please
