Study Notes
Skin Conditions and Components
- Acne results from an overproduction of sebum, causing clogged pores and inflammation.
- Pustules, a type of skin lesion, are commonly associated with acne outbreaks.
Skin Layers
- The epidermis serves as the outermost layer of the skin, providing a barrier for protection and is keratinized to enhance its defense.
- Dermis houses essential structures, including collagen fibers, blood vessels, lymph vessels, nerves, and hair follicles, playing a vital role in skin strength and elasticity.
- The subcutaneous layer, also known as the hypodermis, lies below the dermis and provides insulation and cushioning for underlying tissues.
Glandular Functions
- Sebaceous glands, located in the dermis, secrete an oily substance that nourishes and protects both skin and hair.
- Sweat glands (eccrine glands) assist in regulating body temperature through perspiration, essential for thermoregulation.
Integumentary System Functions
- Key functions of the integumentary system include:
- Protection against environmental hazards.
- Temperature regulation through sweat production and blood flow adjustments.
- Sensation, allowing the body to react to external stimuli.
