Integumentary System Overview
- Dermatologists specialize in diagnosing and treating skin conditions.
- Cosmetic surgeons are experts in both surgical and medical cosmetic procedures.
- Plastic surgeons focus on reconstructing facial and body defects.

Skin Compromise Factors
- Skin's barrier function can be compromised by trauma, chemicals, and infections.
Skin Sensation and Protection
- Nerve endings in the skin detect touch, pressure, heat, cold, pain, and tissue injury, contributing to sensation protection.
- Skin acts as a physical barrier against injuries, chemicals, UV rays, and toxins.
Skin Cell Functions
- Keratinocytes produce keratin, a tough protein crucial for the structural integrity of the stratum corneum.
- Hair originates from epidermal cells at the base of hair follicles.
Recognizing Dermatological Specialties
- A dermatologist is a medical expert in skin diseases.
- Keratin is the protein found in the outer layer of the skin, nails, and hair.
- The cuticle refers to the nonliving epidermis at the base of fingernails and toenails.
Skin Functions and Regulation
- The skin's primary functions include protection, temperature regulation, excretion and secretion, water resistance, and sensation.
- The matrix is the base of the hair follicle where hair growth occurs.
Cancer and Melanin
- Eumelanin and pheomelanin are the two pigments responsible for hair color.
