GENERAL HISTOLOGY

Detailed explanation-1: -The papillary dermis is the superficial layer, lying deep to the epidermis. The papillary dermis is composed of loose connective tissue that is highly vascular. The reticular layer is the deep layer, forming a thick layer of dense connective tissue that constitutes the bulk of the dermis.

Detailed explanation-2: -The papillary layer contains blood vessels to help regulate body temperature while the reticular layer contains hair follicles, nerve endings, and sweat glands. Both layers have intertwined collagen and elastin fibers to protect skin from impact and prevent damage.

Detailed explanation-3: -The thick bottom layer of the dermis (the inner layer of the skin). The reticular dermis has blood vessels and connective tissue that supports the skin. Hair follicles, oil and sweat glands, and other structures are also found in the reticular dermis.
