  1. Metabolic Rate
  2. Complete Proteins
  3. Nodes of Ranvier
  4. Cephalization
  5. Peripheral Nervous System (PNS)
  1. a The total amount of energy an animal uses in a unit of time.
  2. b The sensory and motor neurons that connect to the central nervous system
  3. c Gap in the myelin sheath of certain axons where an action potential may be generated. In saltatory conduction, an action potential is regenerated at each node, appearing to "jump" along the axon from node to node
  4. d An evolutionary trend toward the concentration of sensory equipment at the anterior end of the body.
  5. e ...

5 Multiple Choice Questions

  1. An extension of the hypothalamus composed of nervous tissue that secretes oxytocin and antidiuretic hormone made in the hypothalamus, temporary storage site for these hormones.
  2. ...
  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. The junction where a neuron communicates with another neuron or other cell across a narrow gap via a neurotransmitter(chemical) or an electrical coupling.
  5. In a neuron, a shift in the membrane potential that has an amplitude proportional to signal strength and that decays as it spreads.

5 True/False Questions

  1. Sympathetic DivisionOne 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. Tropic HormonesA hormone that has an endocrine gland or cells as a target.

          

  3. Interstitial FluidOne of the three divisions of the autonomic nervous system; consists of networks of neurons in the digestive tract, pancreas, and gall bladder; normally regulated by the sympathetic and parasympathetic divisions of the autonomic nervous system. (secretions + peristalsis can function independently from parasympathetic and sympathetic but can also be affected by it)

          

  4. ThresholdThe potential that an excitable cell membrane must reach for an action potential to be initiated

          

  5. Gated Ion ChannelGap in the myelin sheath of certain axons where an action potential may be generated. In saltatory conduction, an action potential is regenerated at each node, appearing to "jump" along the axon from node to node
