all right so when we look at the eye we have the extrinsic eye muscles so all the muscles on the outside these are extrinsic eye muscles they each have a name that you don't have to know for this class but you have superior rectus you have lateral rectus medial rectus and then down here there is an inferior rectus muscle there are also two oblique muscles um as well but like i said you just kind of have to know extrinsic eye muscles for this class the white part of the eye so all this white we're seeing here or even if we open this up the white you're seeing here that's going to be the sclera this clear kind of domed portion that you're seeing right here that is the cornea so you have the cornea here when you kind of lift this off we can see the next layer here is the choroid layer so we have sclera and then choroid here we can see the colored part of the eye which is the iris and then the actual space or hole that you're seeing there is the the opening there is the pupil you're seeing that the actual structure that's right there is the lens behind that but the actual hole itself is the pupil you can kind of see when you look in here that there's a space in here so the space that's in here is going to be the anterior chamber and the anterior chamber is filled with aqueous humor and it's that liquidy like watery fluid that's there if we open this up there we can see here you can see there's our scholar [Music] the red right here um that's the choroid layer and then that innermost layer right here the peach layer that's going to be the retina so that's where the rods the cone cells bipolar cells gain glands all those are in the retina then here this is the lens so the lens separates the anterior chamber from the posterior chamber so this is filled with aqueous humor the posterior chamber is filled with vitreous humor so this big plastic piece is supposed to represent the vitreous humor that's found in the posterior chamber but it's that real gelatinous like material in the posterior chamber there when you take that out here you can see the optic disc that's here so that's also called the blind spot because this is where you have all the blood vessels and nerves coming through so there are no photoreceptors so you can't don't have any bit color in our envision or in that spot because it's all the nerve fibers and blood vessels to the side of that over here this kind of like little pink spot there in one of the other eye models it's a purple it's easier to see in the little eye model that has the full extent of muscles but this little spot back here this is going to be the phobia centralis that's going to be where you have the highest concentration of cone cells so that's where you have the best color vision is right there on that phobia centralis so that's a lot of times when you're looking it's hard to see it's like a white pink and this thing i think it has it has a number on this piece right here where it says like 13. it's just a little really light pink layer like i said on the other eye model it's a purple spot so you always see kind of like the optic disc or a blind spot and then if you go to the side it's going to be that phobias and trellises so if you if you're seeing something like this particular spot that's that's what that is like i said it's purple and then one of the other eye models so we can kind of see that all of this kind of together like this would be the optic nerve here like when you put all this together that's the optic nerve that you're seeing there kind of see that inside you have blood vessels you don't have to know the name so you have arteries and veins there inside of you know running along the retina there so you kind of see those you have the ciliary body which is right here i mean it's all of this here but you can see that kind of the thickness that it's a muscle and coming off of that you would have little suspensory ligaments that would attach to the lens and when the ciliary body when that muscle contracts it pulls on the suspensory ligaments that pulls and changes the shape of the lens which allows you to focus either near or far so changing the shape of the lens is going to allow you to focus different distances so that's going to be those ciliary bodies there you can see it right here ciliary body here like i said it's all kind of that right there but here you can kind of see that i like it because you can see the thickness so it's like an actual muscle instead of just like here it looks kind of flat but you kind of see that structure there i think that's everything on that model
