Label the Skin Anatomy Diagram Read the definitions, then label the skin anatomy diagram below. blood vessels - Tubes that carry blood as it circulates. Arteries bring oxygenated blood melanocyte - a cell in the epidermis that from the heart and lungs; veins return produces melanin (a dark-colored pigment oxygen-depleted blood back to the heart and that protects the skin from sunlight). lungs. Pacinian corpuscle - nerve receptors that dermis - (also called the cutis) the layer of respond to pressure and vibration; they are the skin just beneath the epidermis. oval capsules of sensory nerve fibers epidermis - the outer layer of the skin. located in the subcutaneous fatty tissue hair follicle - a tube-shaped sheath that sebaceous gland - a small, sack-shaped surrounds the part of the hair that is under gland that releases oily (fatty) liquids onto the skin. It is located in the epidermis and the hair follicle (the oil lubricated and the dermis. The hair is nourished by the softens the skin). These glands are located follicle at its base (this is also where the hair in the dermis, usually next to hair follicles. grows). sweat gland - (also called sudoriferous hair shaft - The part of the hair that is above gland) a tube-shaped gland that produces the skin. perspiration (sweat). The gland is located hair erector muscle - a muscle is connected in the epidermis; it releases sweat onto the to each hair follicle and the skin - it skin. contracts (in response to cold, fear, etc.), subcutaneous tissue - fatty tissue located resulting in an erect hair and a under the dermis.
