Study Notes
Structure of the Skin
- The skin is composed of three main layers:
- Epidermis: outermost layer, responsible for protecting the body from external factors
- Dermis: middle layer, contains blood vessels, nerve endings, and hair follicles
- Hypodermis: innermost layer, attaches the skin to underlying bones and muscles
Functions of the Skin
- Protection: shields the body from external factors such as temperature, moisture, and UV radiation
- Regulation: helps regulate body temperature, maintain fluid balance, and aid in the production of vitamin D
- Sensation: contains nerve endings that allow for the sensation of touch, pressure, and pain
- Excretion: helps remove waste products through sweat
Skin Types
- Normal skin: balanced skin with a smooth texture and a moderate level of moisture
- Dry skin: characterized by a lack of moisture, often leading to itchiness and irritation
- Oily skin: characterized by an overproduction of sebum, often leading to acne and greasiness
- Combination skin: a mix of dry and oily skin, with oily areas typically on the forehead, nose, and chin
- Sensitive skin: easily irritated by products or environmental factors
Skin Conditions
- Acne: a condition characterized by blackheads, whiteheads, and inflamed pimples
- Eczema: a chronic inflammatory condition characterized by dry, itchy, and scaly skin
