The integumentary system is the body’s largest organ, and it functions to protect and maintain the internal environment by forming a physical barrier between the external and internal environments. The epidermis, dermis, hypodermis, related glands, hair, and nails make up the integumentary system. This system conducts a variety of complex processes in addition to its barrier function, including body temperature management, cell fluid maintenance, Vitamin D production, and stimulus sensing.

  The surface epidermis and the deeper dermis are the two layers that make up the skin. The epidermis is the strong outer layer of the skin that protects it from the elements. It’s made up of four to five layers of stratified squamous epithelial cells. The stratum corneum, stratum granulosum, stratum spinosum, and stratum basale are the fundamental layers, which go from superficial to deep.
  
  Hair is made up of epidermis and dermis roots. The hair shaft, which is visible on the outside, and the hair follicle, which is hidden beneath the skin, are the two parts of its construction. The hair follicle is a complex structure that houses the hair bulb, which divides to lengthen the hair shaft vertically.
  
  The scalp extends from the top of the forehead to the epicranial aponeurosis of the skull, covering the entire surface of the head. It reaches down to the external auditory meatus and zygomatic arch on the lateral side (cheekbone of the skull). The skin, connective tissue, epicranial aponeurosis, loose connective tissue, and pericranium are the five layers that make up the scalp (periosteum).
