Study Notes
Nail Follicles
- Located at the ends of fingers and toes
- Mitosis takes place in the nail root
- The nail itself is dead, keratinized cells
- Protect the ends of fingers and toes
- Enable fingers to pick up objects
- Provide for efficient scratching
Sebaceous Glands
- Produce sebum, preventing skin and hair drying, and inhibiting bacterial growth
- Located in the skin
Ceruminous Glands
- Produce cerumen, preventing the eardrum from drying
- Located in the skin
Eccrine Sweat Glands
- Produce watery sweat that evaporates, cooling the body
- Located in the skin
Arterioles
- Dilate in response to warmth, increasing heat loss
- Constrict in response to cold, conserving body heat
- Constrict in stressful situations, shunting blood to vital organs
Receptors
- Detect changes in touch, pressure, heat, cold, and pain
- Provide information about the external environment
- Initiate appropriate responses
- Sensitivity of the skin depends on the receptors
