=Sweatology Notes (Dr. Field)=

6 Major Topics

 * Excretory System (Skin, Sweating)


 * The more sweat glands = more (copius) sweat. (2 to 4 million sweat glands)
 * The bigger sweat glands = more (copius) sweat (more sensitive to nerve stimuli, a nerve sends a signal from the brain to the sweat gland to secrete sweat)


 * Body Temperature Regulation (Nervous and Endocrine System)


 * The bigger sweat glands = more (copius) sweat (more sensitive to nerve stimuli, a nerve sends a signal from the brain to the sweat gland to secrete sweat).
 * When does the brain send a signal via the nerve to the sweat gland? When nerves in the skin detect temperature and send a signal to the brain when skin is too hot.
 * When the skin is at a temperature in the 90s (whether the heat source is internal--muscles contract they generate heat--heat is waste of cellular respiration-- or external like weather) a signal is sent to the brain via nerve to stimulate sweat.


 * Circulatory System (Heart and Blood Vessels)
 * Medical Consequences of Heat Stress
 * Water
 * Salt
