The dermis, a layer of skin beneath the epidermis, contains numerous vital structures. Here are 5 key structures found within the dermis:
-
Connective Tissues: The dermis is primarily composed of connective tissues such as collagen and elastin. These fibers provide strength, elasticity, and support to the skin.
-
Nerve Endings: The dermis is densely populated with various nerve endings responsible for sensing touch, pressure, temperature, and pain. These sensory receptors allow us to interact with our environment.
-
Sweat Glands: These glands, also known as sudoriferous glands, produce and secrete sweat to regulate body temperature through evaporative cooling.
-
Oil Glands: Also called sebaceous glands, these glands secrete sebum, an oily substance that lubricates and waterproofs the skin and hair.
-
Hair Follicles: These are tube-like structures within the dermis from which hairs grow. Each hair follicle is associated with a sebaceous gland and a small muscle called the arrector pili muscle, which causes "goosebumps."
