Study Notes
Skin Layers and Functions
- The most superficial layer of the skin is the epidermis. It acts as a protective barrier against environmental hazards.
Dermis Functionality
- The dermis lies beneath the epidermis and provides structural support and elasticity to the skin through its connective tissue. It also houses blood vessels, nerve endings, and hair follicles.
Collagen and Elastic Fibers
- The dermis contains collagen and elastic fibers, which contribute to skin strength and elasticity, aiding in skin repair and resistance to stretching.
Melanin Determination
- The amount and type of melanin in the skin are regulated by melanocytes, specialized cells that produce melanin in response to UV exposure and genetic factors.
Stratum Corneum Composition
- The primary composition of the stratum corneum, the outermost layer of the epidermis, consists of dead keratinized cells that provide a durable barrier and help prevent water loss.
