The primary function of the dermis is to support the epidermis and enable the skin to thrive. It also plays several other critical roles, including:
- Protection: Acting as a barrier against external threats like bacteria, viruses, and UV radiation.
- Sensation: Containing nerve endings that transmit touch, pressure, temperature, and pain signals to the brain.
- Thermoregulation: Regulating body temperature through sweat glands and blood vessels.
- Repair and regeneration: Containing cells that help repair and regenerate skin tissues.
The dermis is a thick layer of connective tissue located beneath the epidermis. It's made up of collagen, elastin, and other proteins that provide strength, flexibility, and elasticity to the skin. Its rich network of blood vessels nourishes the epidermis and helps regulate temperature.
The dermis also houses various structures, including hair follicles, sweat glands, sebaceous glands, and nerve endings, which contribute to its diverse functions.
