GENERAL HISTOLOGY

Detailed explanation-1: -Your dermis contains collagen and elastin, which help make your dermis thick and supportive of your skin’s overall structure. All of your connective tissues, nerve endings, sweat glands, oil glands and hair follicles exist in your dermis.

Detailed explanation-2: -Thin skin covers most of the body and contains sweat glands, in addition to hair follicles, hair arrector muscles, and sebaceous glands.
