Dermis layers
1. papillary layer2. reticular layer
The dermis, which is the second and thickest layer of the skin, is made up of two main layers:
1. Papillary layer: This is the thinner layer of the dermis that lies just below the epidermis. It is composed of loose connective tissue and contains blood vessels, lymphatic vessels, and sensory nerve endings. This layer is responsible for supplying nourishment to the epidermis and aids in the regulation of body temperature.
2. Reticular layer: This is the deeper and thicker layer of the dermis. It is composed of dense irregular connective tissue and is responsible for providing strength and flexibility to the skin. The reticular layer contains many important structures such as sweat glands, sebaceous glands, hair follicles, sensory receptors, blood vessels, and lymphatic vessels.
The dermis layers work together to provide the skin with its unique properties of strength, elasticity, and sensitivity.
