  4. Multipolar Neuron
  5. Excitablity
  1. a The ability to respond to stimuli and convert them into nerve impulses
  2. b The membrane has become more negative than resting potential. Until the channels close.
  3. c What period is it when the sodium ion channels are open, the membrane is totally insensitive to additional stimuli, regardless of the force of the stimulus?
  4. d one axon and multiple dendrites; efferent neurons and interneurons are multipolar
  5. e essentially rough endoplasmic reticulum, important metabolically

5 Multiple choice questions

  1. one single process leading away from the soma; afferent neurons are unipolar
  2. neuron serving as part of the conduction pathway between sensory and motor neurons; association neurons
  3. Another name for the action potential in neurons.
  4. Phagocytize and destroy microorganisms, foreign matter, and dead nervous tissue
  5. What toxin blocks synaptic transmission by preventing the flow of neural impulses from neuron to neuron?

5 True/False questions

  1. deep pressure, cold temperatureThe amt of stimulus needed to create an action potential. NA+ rushes into the cell increasing the number of positive ions inside the cell and changing the membrane polarity


  2. Dendritereceptive region of a neuron


  3. PNS - Peripheral Nervous SystemGanglia and spinal and cranial nerves


  4. Epineuriumbinds all of the fascicles together


  5. Conduction VelocityWhat is the name of the velocity of the action potential along a neural membrane?
