The integumentary system is the body’s largest organ, serving to protect and maintain the internal environment by forming a physical barrier between the external and internal environments. The epidermis, dermis, hypodermis, corresponding glands, hair, and nails are all part of the integumentary system.
1. Epidermis – The epidermis is your body’s outermost layer of skin. It defends your body from injury, keeps it moisturized, generates new skin cells, and includes melanin, which gives your skin its color.
2. Hair Follicle – Hair growth is controlled by a complex combination of hormones, neuropeptides, and immune cells in the hair follicle.
3. Human Scalp – The soft tissue layers that cover the cranium make up the scalp. The scalp consists of 5 layers: the skin, connective tissue, epicranial aponeurosis, loose areolar tissue, and pericranium.
