Study Notes
Papillae and Identification
- Papillae are structures covering the top of the dermis.
- Unique patterns of papillae create individual fingerprints and footprints, aiding in personal identification.
Sweat and Oil Glands
- Proper name for sweat glands is sudoriferous glands.
- Perspiration contains water, salts, and body waste.
- Oil glands are known as sebaceous glands, producing sebum to maintain skin moisture.
Hair and Skin Functions
- Alopecia refers to baldness and signifies a permanent loss of hair on the scalp.
- Skin serves seven essential functions: protection, sensory perception, temperature regulation, storage, absorption, excretion, and production.
Temperature Regulation
- When blood vessels dilate, excess body heat escapes through the skin, cooling the body.
- Blood vessel constriction retains heat, helping maintain body warmth.
Skin Conditions and Disorders
- Erythema results in reddish skin, typically caused by burns or blood congestion.
- Jaundice manifests as yellow skin discoloration due to liver or gallbladder issues.
