5 Multiple Choice Questions

  1. Part of the nervous system that senses and controls information with afferent and efferent neurons.
  2. Labor and delivery: baby's head on cervix → impulse to brain → stimulated pituitary → oxytocin secreted → uterine muscle contraction → more pressure on cervix (repeat); ends after placenta delivered.

    Hemostasis (blood clotting): [vessel ruptures] collagen fibers attract blood platelets → platelets attract clotting factors (Hageman factor) → prothrombin → thrombin → fibrinogen → fibrin → attracts more platelets (repeat).

    Nerve impulse: depolarization at one Na channels causes a cascade (repeat).
  3. Negative and Positive
  4. Painful muscle spasms due to excessive electrolyte loss in sweat.
  5. * Selective permeability
    * Active transport: excretion (waste removal), or secretion (product)
    * Adhesion
    * Communication (receptors)
    * Motility, movement of fluids

5 True/False Questions

  1. Phospholipid BilayerLow permeability to water-soluble substances (e.g. ions, glucose, and amino acids), but permeable to lipid-soluble substances (e.g. fatty acids, oxygen, and carbon dioxide).

          

  2. InnateCrisis of fever occurring at the end of febrile condition. Patient has 105 °F temperature, hypothalamus trying to maintain 98.6 °F and is still hot, leads to intense sweating and vasodilatation causing the skin to be hot.

          

  3. Robert HookeProlonged heat exposure with high humidity. Body gains heat by radiation and convection while evaporative cooling is retarded. Can lead to convulsions, coma, and death.

          

  4. Heat Loss from SkinProlonged heat exposure with high humidity. Body gains heat by radiation and convection while evaporative cooling is retarded. Can lead to convulsions, coma, and death.

          

  5. Leeuwenhoek (1632-1723)Coined the term "homeostasis" - the body's tendency to maintain relatively stable internal conditions (the CENTRAL unifying concept of physiology).
