Study Notes
Integumentary System Overview
- The hair follicle is found in the dermis, which is the deeper layer of the skin.
- Hair is classified as an appendage of the skin, serving various functions including protection and temperature regulation.
- The dermis also houses nerves, blood vessels, and glands, essential for sensory perception and homeostasis.
Skin Anatomy
- The nail matrix is located in the nail bed, responsible for nail growth.
- The cortex forms the outer layer of hair, providing strength and protection.
- The subcutaneous layer is the innermost layer of skin, containing fat and connective tissue.
Functions of the Integumentary System
- Absorption function allows medications like nitroglycerin to enter the body through skin patches.
- The sensory system incorporates receptors for touch, cold, and pain, enhancing the body's awareness of external stimuli.
- Regulation of body temperature is achieved through the evaporation of perspiration, which cools the skin surface.
Skin Injuries and Disorders
- A first degree burn results in skin redness without blisters, often from mild sun exposure.
- A second degree burn involves blister formation due to exposure to hot substances, such as oil.
- Athlete's foot is a fungal disorder that can be mitigated through good personal hygiene practices.
Skin Conditions and Evaluations
- Increased sebum production during adolescence can lead to acne, a common skin disorder.
- Melanoma is signified by skin lesions with irregular borders, multiple colors, and growth; tanning bed use raises risk factors.
- The integumentary system offers protection as the body's first line of defense against harmful substances.
Dermatitis, Warts, and Infections
- Dermatitis occurs due to allergens, harsh chemicals, or frequent hand washing, resulting in skin inflammation.
- A viral skin lesion that can recur post-removal is classified as a wart.
- Herpes simplex type 2 is recognized as a skin condition that is also classified as a sexually transmitted infection.
Prevention Tips
- Prevent athlete's foot by avoiding shared towels and wearing shower shoes in communal areas, such as locker rooms.
