what is the common between the genes of temperature regulation and gene of nail production
Answers
Answer:
Hair is part of the integumentary system. Strands of hair originate from the base of the downward extension of living epithelial cells into the dermis that is called the hair follicle. Hair follicles are surrounded by the dermis, but the cells are part of the epidermis and are separated from the dermis by basal lamina layer. Hair forms in a manner similar to the skin: rapid division and differentiation of stem cells into keratinocytes that get pushed up and become flattened, dead, keratinized cells. The part of hair that is exposed on the skin surface is called the hair shaft, and the rest of the follicle is called the hair root. The bulge at the base of the hair root is called the hair bulb, which is made up of a layer of basal cells called the hair matrix. The hair matrix contains the cells that rapidly divide to form the hair. The hair bulb surrounds the hair papilla (made up of connective tissue, blood capillaries and nerve endings).
