A&D F. B&C 5. Which of the following is true regarding the epidermis: It is highly vascular. It is comprised of five distinct layers. The basement membrane contains its blood supply. Epidermal ridges change throughout a person’s lifetime. 5. Which of the following is false regarding the epidermis: It is avascular. As cells divide they are pushed towards the basement membrane. (False, as cells divide they are pushed towards the external surface of the stratum corneum) The cells of the stratum basale cells have a high rate of cell division. Epidermal ridges form a person’s fingerprints.
