What are the two layers of the dermis called?

The two layers of the dermis are known as the papillary layer and the reticular layer. The papillary layer is the uppermost layer of the dermis, characterized by thin, loose connective tissue that contains capillaries, lymphatics, and sensory neurons. This layer is vital for supplying nutrients to the skin and plays a role in thermoregulation and sensation.

Beneath the papillary layer lies the reticular layer, which is thicker and made up of dense, irregular connective tissue. This layer contains a network of collagen and elastin fibers, providing strength and elasticity to the skin. The reticular layer houses larger blood vessels, sweat glands, sebaceous glands, hair follicles, and connective tissues, contributing to the skin's overall structure and function.

Understanding the structure and function of these two layers is critical for appreciating how the dermis supports skin health, contributes to sensory functions, and plays a role in the healing process.
