  1. a One of the three divisions of the autonomic nervous system, generally enhances body activities that gain and conserve energy, such as digestion and reduced heart-rate, decrease breathing, storing glycogen for energy in the liver
  2. b The junction where a neuron communicates with another neuron or other cell across a narrow gap via a neurotransmitter(chemical) or an electrical coupling.
  3. c An evolutionary trend toward the concentration of sensory equipment at the anterior end of the body.

5 Multiple choice questions

  1. The sensory and motor neurons that connect to the central nervous system
  2. ...
  3. An electrical change (depolarization) in the membrane of a post-synaptic cell caused by the binding of an excitatory neurotransmitter from a presynaptic cell to a post-synaptic cell; makes it more likely for a post-synaptic cell to generate an action potential.
  4. ...
  5. The internal systems of communication involving hormones, the ductless glands that secrete hormones directly into the interstitial fluid, from which they diffuse into the bloodstream.

5 True/False questions

  1. Graded PotentialIn a neuron, a shift in the membrane potential that has an amplitude proportional to signal strength and that decays as it spreads.


  2. Muscle TissueTissue made up of neurons and supportive cells.


  3. MyofibrilsA type of motor protein that associates into filaments that interact with actin filaments to cause cell contraction


  4. Incomplete Proteins...


  5. Enteric DivisionOne 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)
