Telogen effluvium: Loss of hair during its rest phase. Like other organs, you can have problems with your integumentary system like acne, hair loss or nail fungus. Acne occurs when the pores of the skin become blocked with sebum, bacteria, and dead skin cells. There are two types of sweat glands, eccrine and apocrine and each one produces a different type of sweat. Sample answer: Hair originates from hair follicles, which are found in the dermis of the skin. In addition to these specialized receptors, there are sensory nerves connected to each hair follicle, pain and temperature receptors scattered throughout the skin, and motor nerves innervate the arrector pili muscles and glands.

Integumentary system: Definition, diagram and function. These glands will be discussed in much greater detail in a later chapter. Many epithelial cells are capable of secreting mucous and other specific chemical compounds onto their apical surfaces. The nerve impulses (such as the perception of pain, heat, cold, and other sensations) are then transmitted to the nervous system to be interpreted by the brain. Calcium is needed for the growth and maintenance of bones, as well as for muscle contractions.

It comprises the skin, hair, nails, and glands that produce sweat and oil. Stem cells in the nail matrix keep dividing to allow nail growth, forming first the nail root and then the nail plate as the nail continues to grow longer and becomes visible. She enjoys giving lectures and writing articles for both the lay public and medical audiences. The papillary layer has papillae extending upward toward the epidermis; the reticular layer lacks such papillae. Each hair follicle also has a sebaceous gland that secretes sebum into the follicle and a tiny arrector pili muscle that moves the follicle and causes the hair to stand up when it contracts. Vitamin D production: When exposed to UV light from the sun, the skin produces vitamin D, which is important for bone health. These junctions thus allow electrical and metabolic coupling of adjacent cells. Single cell layers form simple epithelia, whereas stacked cells form stratified epithelia. Sample answer: Keratinocytes are born in the deepest layer of the epidermis and then are pushed outwards as new keratinocytes are born.
