Study Notes
Integumentary System Overview
- The integumentary system is the largest organ system in the body, comprising the skin, hair, nails, and glands.
- A key function of the system is its role in maintaining temperature via thermoregulation mechanisms.
Skin Structure
- The skin has three layers: epidermis, dermis, and subcutaneous tissue.
- The epidermis, the outer layer, consists of flattened, dead cells providing a protective barrier.
- Melanocytes in the epidermis produce melanin, influencing skin color.
- The dermis, the middle layer, contains blood vessels, hair follicles, sweat glands, nerves, and oil glands.
- The subcutaneous tissue (hypodermis), the innermost layer, is primarily fat, acting as an insulator and shock absorber.
Functions of the Integumentary System
- Protection: The skin acts as a barrier against external factors like bacteria, toxins, and viruses.
- Temperature Regulation: The system helps regulate body temperature through vasodilation (widening blood vessels) when it's hot, and vasoconstriction (narrowing blood vessels) in cold conditions.
- Sensation: Nerve endings in the skin detect diverse stimuli like hot, cold, pain, pressure, and touch.
- Vitamin D Production: The skin plays a role in converting a precursor to vitamin D when exposed to sunlight.
Hair and Nails
- Hair and nails are composed of keratin, a protein providing strength.
- Hair follicles play a part in hair growth, and hair contributes to insulation.
- Nails and their associated structures provide protection and aid in grasping objects.
Sweat Glands
- Eccrine sweat glands are spread across the body, opening directly onto the skin to release sweat regulating body temperature.
- Apocrine sweat glands, concentrated in certain areas, open into hair follicles.
Skin Disease overview
- Several skin diseases exist, including acne vulgaris (inflammation of the skin), psoriasis (autoimmune skin condition), melanoma (skin cancer), carcinoma (most common form of cancer), and athlete's foot (fungal infection).
- Each skin disease carries distinct symptoms, causes, treatment options, and prevalence.
- Understanding skin diseases can lead to appropriate preventative measures or treatment.
Thermoregulation
- The body's optimal temperature for enzyme function is 37°C.
- Homeostasis maintains body temperature.
- Shivering and vasoconstriction are mechanisms to keep warm.
- Sweating and vasodilation are mechanisms to cool down the body.
