Study Notes
Integumentary System
- The integumentary system consists of the skin and accessory structures, such as hair, glands, and nails.
- The skin is composed of the epidermis and the dermis.
- The appearance of the integumentary system can be affected by physiological imbalances.
- Disorders such as acne and warts can affect the integumentary system.
- Other disorders can be reflected in the integumentary system, providing useful signs for diagnosis.
- Reduced blood flow through the skin can cause a person to look pale.
- Increased blood flow can cause a flushed appearance.
- Some diseases cause skin rashes, such as those characteristic of measles, chickenpox, and allergic reactions.
Tanning
- Sunlight exposure increases melanin production in the skin, contributing to a tan.
- Loss of sunlight exposure in the fall could cause the tan to fade because melanin production decreases as the skin produces fewer melanocytes.
- This is because melanin is the pigment that gives skin its color and helps protect the skin from harmful UV rays.
