Study Notes
Skin Function
- The primary function of the skin is to act as a protective barrier against external factors like:
- Physical damage
- Harmful microorganisms
- Ultraviolet radiation
- Chemical exposure
Sensory Layer
- The dermis is primarily responsible for sensation, containing nerve endings that detect touch, temperature, and pain.
Protective Barrier
- The epidermis, the outermost layer of the skin, contains a tough protein called keratin which provides its primary protective barrier.
Melanin Function
- Melanin is a pigment produced by specialized cells called melanocytes, responsible for determining skin color. It plays a vital role in protecting the skin from UV radiation damage.

- Provides insulation
- Cushions the body against impact
- Stores energy
