GENERAL HISTOLOGY

Detailed explanation-1: -Reticular dermis: The reticular layer is the bottom layer of your dermis. It’s thick, and it contains blood vessels, glands, hair follicles, lymphatics, nerves and fat cells. A net-like structure of elastin fibers and collagen fibers surrounds the reticular dermis.

Detailed explanation-2: -The reticular layer also contains hair follicles, sweat glands, and sebaceous glands. The sweat gland can either be apocrine, such as those found in the armpits and the groin area, or the eccrine glands, which are found all over the body.

Detailed explanation-3: -Skin includes several specialized structures, including epidermal appendages (sweat glands, hair follicles, nails) as well as blood vessels and nerve endings which travel through the dermis. Epidermal appendages play an especially important role in recovery from superficial scrapes and burns.

Detailed explanation-4: -The hair follicle begins at the surface of the epidermis. For follicles that produce terminal hairs, the hair follicle extends into the deep dermis, and sometimes even subcutis. Meanwhile, follicles producing vellus hairs extend only to the upper reticular dermis.
