Document Summary

Some melanocytes and produce melanograduate and that can be taken up by the keratinized cells. The root sits inside the dermis and made up live ep cells that are rapidly growing. How much of the melanocyte will determine the colour of the hair follicle. Hair that you see on an indiv is made up mostly of dead keratinized cells. Cells (cid:272)a(cid:374) lose a(cid:271)ilit(cid:455) to store (cid:373)ela(cid:374)i(cid:374) o(cid:272)(cid:272)urs as (cid:449)e age. Certain hormones act on the root of the hair follicle: can either increase growth or stunt the growth, e(cid:454), hair loss i(cid:374)a(cid:271)ilit(cid:455) to (cid:373)ake hair folli(cid:272)les. Certain glands attached to the follicle that lay next to the root. Sebaceous gland produce sebum (grease) moistens the hair follicle and the skin. Made up of epithelial cells bc those are the cells that secrete. Exist within the dermis that make their way up to the surface of the skin. Why we seat: use it as a cooling mechanism.
