In this video, we're going to focus on the epidermis, specifically the cells of the epidermis. Now, recall from our previous lesson videos that the epidermis is the outermost layer of the skin and is composed of stratified squamous epithelial tissue, or many layers of these flat or squished cells. Now, notice over here on the right we have a diagram of the integumentary system. And notice that the only layer that is colored is the epidermis, which you can see is the outermost layer of the skin.
Now, there are actually 4 main types of cells in the epidermis that we have numbered down below. And they are keratinocytes, melanocytes, dendritic cells, and tactile epithelial cells. Moving forward in our course, we're going to talk more details about each of these 4 types of cells, starting with the keratinocytes in our next lesson video. So I'll see you all there.
