  1. a Interstitial fluid (tissue fluid between cells); Blood Plasma; Lymphatic Fluid; Pleural Fluid; Pericardial Fluid; Cochlear and Ocular fluids; and the fluid in the tunic of the testes.
  2. b 60% found in the brain, 1 trillion cells, 100 billion in brain, communicate via action potentials, generate action and electrical potentials.
  3. c Increased metabolic rate (20-30%), more nutrients utilized, more calories consumed.
  4. 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.
  5. e Conducts sensory information to central nervous system (CNS). Detects stimuli that originate outside the body as well as within the body.

5 True/False Questions

  1. Chemical Thermogenesis (Mechanism)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.


  2. HypothalamusCondition due to cold weather or icy water. Core temperature < 91 °F. Leads to sleep, coma, and death.


  3. Artificial HypothermiaUseful for heart surgery when the heart must be stopped for several minutes at a time. Myocardial cells can survive 30-60 minutes even without blood flow. Patient's temperature maintained at 90 °F.


  4. Efferent Neuronssodium, chloride, calcium, bicarbonates, nutrients for cells (e.g. glucose, fatty acids, amino acids), oxygen and carbon dioxide


  5. Fever (Pyrexia)The original secretion of the sweat gland's coiled duct. Devoid of proteins, NaCl ions are reabsorbed. All salt reabsorbed when sweat gland stimulation is slight, only half when stimulation is strong.
