Answer explanation

Distinguish whether these statements describe the epidermis or dermis.

Groups:

(a) Epidermis

,

(b) Dermis

• 4-5 layers thick depending on location

• 2 layers thick

• Responsible for creating goosebumps

• Thicker part of the skin

• Vasculartized

• Avascular

• Makes up most superficial layer of skin

• Contains melanocytes that produce melanin

• Contains Langerhans cells for immune response

• Contains plentiful amounts of collagen and elastin fibers

• Made up of mainly keratinocytes

• Sweat and oil glands secrete substances over top of this

• Glands and hair follicles originate here
