Explanation:

In humans and superior animals, the skin is the most external layer of the body, fulfilling functions of protection and relationship with the outside, among others. The different components that can be observed, related to the skin, are

Hair shaft: it is found on the surface of the skin, while its root is associated with the hair follicle found in the dermis. Keratinocytes: these cells are found in the outermost layers of the skin, producing keratin, the substance that allows the skin to be resistant. Blood vessels: the capillaries and small-caliber vessels that nourish the skin are found in the dermis. Fat: the hypodermis, or subcutaneous cellular tissue, is the third layer that forms the skin and is made up of fat cells. Muscles: the muscles are found underneath the hypodermis, covered by an aponeurotic facia that provides them with coverage. It is the deepest plane, before reaching the bone plane.
