The skin is composed of three layers. The epithelium forms the surface later, the epidermis which is usually the darkest layer. The dermal papillae is the irregular border between the epidermis and the dermis. The dermis appears lighter than the epidermis and is composed of dense, irregular connective tissue.
A hair follicle is a tubular invagination line by stratified squamous epithelium similar to epidermis with a central lumen that may contain a hair shaft, Usually, each hair follicle is associated with a sebaceous gland.
Sebaceous glands are associated with hair follicles. The complex of the hair follicle, hair shaft, and sebaceous gland is called pilosebaceous apparatus.
