all right home kids not only do we have to talk about where structures are in relation to each other sometimes we have to talk about cuts in the body in actuality if you take a slice if you cut a body in half you you do a section and then you open that up you're gonna see a whole bunch of structures in there and you can identify those structures and we can learn a lot about their location and their overall the way they're built by looking at and thinking about the plane in which that section was made the cut was made so there are actually three um different ways we can slice the human body and being able to visualize slices is gonna help you tackle some pretty challenging spatial tasks in this class if I did any one of these slices the section that is sliced is gonna be flat right and yet it's a flat slice of a three-dimensional structure so um knowing the plane in which we are slicing is going to help us know what anatomical structures we might find in that plane okay so here are your planes check this guy out we have I'm looking at this one and my pen of course is not working which I'm trying not to get super cranky I don't think I'm being successful at that what I just drew on this plane is dividing the body into front and back I think it's gonna go crazy in a second when it decides that it is gonna start writing maybe right now I'm just not gonna right I'm sorry I'm just not gonna write and instead you are going to know that this one is dividing the body into a front half and a back half and that is the frontal or coronal plane so if I slice the body and I end up with something that's front and something that's back I've made a frontal section or a coronal section the coronal makes you think of a crown or the corona of the Sun and so that's how I actually remember the plane that that section is in I imagine myself wearing a Sun Hat with a whole bunch of sunbeams coming out of my head in the coronal plane the section that is oh look maybe it'll work now nobody knows the section that divides my body into a left half and a right half it was a good effort that section is a sagittal section so sagittal sections do right and left a midsagittal section or a median section is right down the midline but you can have a sagittal section that's not down the midline it's an interesting question if I did a sagittal section right here is how do you know if it's mid sagittal or sagittal and you're gonna look for clues that will tell you that do that's not the midline if you caught the heart like a big chunk of heart in your sagittal section you probably are not mid sagittal midsagittal you're probably just gonna catch a little little chunk of heart not a big chunk of heart do you catch lungs you're not mid sagittal if you go right down the middle you shouldn't catch any lungs in your mid sagittal section the last section here is the transverse section that divides the body into an upper and a lower half even though I couldn't write down a single thing for you you better write down what I said and that is like this is a normal lecture and so you have to take notes and if I in my normal lecture have tech issues and can't write anything down for you then you get to deal with that okay I'm going to try and fix the tech issues for the last one and we'll do body cavities
