- a Comprised of the brain which stores information and compares to it, generates thoughts, and creates emotions and ambitions; as well as the interneurons (90% of the neurons in the central nervous system) that bridge the gap between sensory and motor neurons that receive information from different sources, interpret and transmit information to other cells, and store it in memory.
- b Epinephrine, nor epinephrine, and thyroxin cause uncoupling to occur reducing the number of ATP's produced in the electron transport in the aerobic pathway. Fewer ATP's results in greater heat (26 less ATP * 7.3 kcal / ATP = 189.9 kcal of heat). Infants can double heat production; adults can have a 10-15% increase.
- c * Isolates the cell
* Regulates the intracellular and extracellular ionic environment
* Comprised of a phospholipid bilayer
- d A rapid self-amplifying cycle; a physiological change leads to greater changes in the same direction; the response ENHANCES the original stimulus; unstable, less frequent, and may be destructive.
- e Tissue that surrounds and supports neurons in the central nervous system; support, protect, and nourish the neurons.

- These cells are found only on outer half of the lipid bilayer as a thin sugar coating, called the cell coat or glycocalyx. Cell communication: receptors for binding hormones, cell adhesion (cohesive tissue), immune reaction.
- Dominated by theology; Saint Augustine believed that all natural phenomena had supernatural causes; Dark Ages.
- A process in which the body senses a change and activates a mechanism that reverses that change; its function is to maintain stable internal environmental conditions; closed loop system.
- Transfer of heat from the body by currents (air and water).
5 True/False Questions
Total Blood Volume → (Intracellular fluid component) ~1.6 liters in adults
Claude Bernard (1813-1878) → Published a textbook "The Canon of Medicine", leading authority for 600 years in Europe.
Heat Exhaustion → 22% of heat loss. Sweat glands and exhalation provide liquid. Water off skin and out of lungs occurs at a rate of 450-600 mL/day = 12-16 kcal/hour of heat.
Radiation → 60% of heat loss. Molecular motion produces infra red which the body releases in all directions.
Rate of Heat Loss → sodium, chloride, calcium, bicarbonates, nutrients for cells (e.g. glucose, fatty acids, amino acids), oxygen and carbon dioxide
