  3. Essential Nutrients
  4. Sympathetic Division
  5. Autonomic Nervous System
  1. a An efferent branch of the vertebrate peripheral nervous system that regulates the internal environment; consists of the sympathetic, parasympathetic, and enteric divisions.
  2. b One of the tree divisions of the autonomic nervous system; generally increases energy expenditure and prepares the body for action (Fight or Flight) - causes increase in heart rate, breathing, slows digestion, liver releases glucose, inhibits emptying of bladder, releases adrenaline from adrenal medulla situations:(emergency, embarrassment, exercise, excitement)
  3. c An organism that is warmed by heat generated by their own metabolism, Heat usually maintains a relatively stable body temperature higher than that of the external environment.
  4. d A substance that an organism cannot synthesize from any other material and therefore must absorb in preassembled.
  5. e ...

5 Multiple choice questions

  1. Sheets of tightly packed cells that line organs and body cavities as well as external surfaces
  2. In a neuron, a shift in the membrane potential that has an amplitude proportional to signal strength and that decays as it spreads.
  3. The short time immediately after an action potential in which the neuron cannot respond to another stimulus, owing to the inactivation of voltage-gated sodium channels
  4. ...
  5. The sensory and motor neurons that connect to the central nervous system

5 True/False questions

  1. Myelinated SheathThe total amount of energy an animal uses in a unit of time.

          

  2. Muscle TissueTissue consisting of long muscle cells that can contract, either on its own or when stimulated by nerve impulses

          

  3. Spatial SummationA phenomenon of neural integration in which the membrane potential of the post-synaptic cell is determined by the combined effect of EPSPs or IPSPs produced nearly simultaneously by different synapses.

          

  4. DepolarizationA change in a cell's membrane potential such that the inside of the membrane is made less negative relative to the outside. For example, a neuron membrane is depolarized if a stimulus decreases its voltage from the resting potential of -70 mV in the direction of zero voltage.
