 So now we're starting into the special senses. So this is going to be our our vision our hearing coordination and our taste Okay, so looking here at the eye Okay, so we already went over your individual muscle groups on there. So make sure you review that From the muscle chapter. We can see the white part of the eye So you have three layers on the eye itself the sclera is the white part the second layer Is this darker part here? So this is our vascular layer called the CROID layer Again, we remove that and on the inside You have your retina. So that's the lighter layer there. That's got all the nerve tissue associated with it So coming from the back of the eye Is your optic nerve coming in there? Okay, so I'm gonna remove a few things. We'll come back to those And we can see the optic disc Right here. That's where the optic nerve is coming into the retina Okay You can also see so if this is the optic disc just adjacent to it There's in this model. It's kind of a pink dot, but it's another reading called the macula Lidia And right in the middle of it. So in the middle of the macula Lidia is the fove centralis Okay So filling that region Okay, so everything from this point back Is our posterior cavity and this big clear structure here is representing the vitreous body Which is kind of a gooey substance back in there in a real eye Okay, so that's our posterior cavity in the anterior cavity We start with our lens so the lens sits kind of in a cavity within that vitreous body And sits behind the pupil the pupil being the hole in the iris the iris is the colored part of the eye All that sits behind the cornea the cornea is the clear layer that surrounds the eye itself We take all that apart Now we want to look on the inside here, okay So we have a ciliary body So that's all this structure you're seeing here the ciliary muscle Is this in this particular model? It's kind of the smoother outer layer here But it is a muscle itself which connects to suspensory ligaments and these ligaments are gonna constrict or contract The pupil and that makes up the anterior cavity
