skin forms the protective outer layer covering the external surfaces of the entire body.
sebaceous glands secrete sebum (oil) that lubricates the skin and discourages the growth of bacteria on the skin

Hair helps control the loss of body heat.
Nails protect the dorsal surface of the last bone of each toe and finger.
cutaneous pertaining to the skin
epidermis which is the outermost layer of the skin, is made up of several specialized epithelial tissues
Epithelial tissues form a protective covering for all of the internal and external surfaces of the body.
Squamous epithelial tissue forms the upper layer of the epidermis. Squamous means scale-like. This layer consists of flat, scaly cells that are continuously shed.
basal layer the lowest layer of the epidermis. It is here that new cells are produced and then pushed upward. When these cells reach the surface, they die and become filled with keratin.
Keratin a fibrous, water-repellent protein. Soft keratin is a primary component of the epidermis. Hard keratin is found in the hair and nails.
Melanocytes are special cells that are also found in the basal cell layer. These cells produce and contain a dark brown to black pigment known as melanin.
Melanin the pigment that determines the color of the skin, which depends upon the type and amount of this pigment that is present
dermis also known as the corium, is the thick layer of living tissue directly below the epidermis. It contains connective tissue, blood and lymph vessels, and nerve fibers. Also found in the dermis are the hair follicles, sebaceous glands, and sweat glands
Sensory nerve endings dermis are the sensory receptors for stimuli such as touch, temperature, pain, and pressure.
Collagen which means glue, is a tough yet flexible fibrous protein material found in the skin and also in the bones, cartilage, tendons, and ligaments.
Mast cells found in the connective tissue of the dermis, respond to injury, infection, or allergy by producing and releasing substances, including heparin and histamine.
Heparin which is released in response to an injury, is an anticoagulant. An anticoagulant prevents blood clotting.
Histamine which is released in response to allergens, causes the signs of an allergic response, including itching and increased mucus secretion.
subcutaneous layer located just below the layers of the skin and connects the skin to the surface muscles.
adipose tissue Adipose means fat
Lipocytes also known as fat cells, are predominant in the subcutaneous layer where they manufacture and store large quantities of fa

mammary glands which are modified sweat glands, are sometimes classified with the integumentary system. However, they also are part of the reproductive system
Hair (fibers) are rod-like structures composed of tightly fused, dead protein cells filled with hard keratin. The darkness and color of the hair is determined by the amount and type of melanin produced by the melanocytes that surround the core of the hair shaft.
Hair follicles are the sacs that hold the root of the hair fibers. The shape of the follicle determines whether the hair is straight or curly.
arrector pili tiny muscle fibers attached to the hair follicles that cause the hair to stand erect. In response to cold or fright, these muscles contract, causing raised areas of skin known as goose bumps. This action reduces heat loss through the skin.
