5 Written questions

5 Matching questions

  1. what are examples of excitatory transmission?
  2. resting membrane picture
  3. saltatory conduction
  4. afferent
  5. dendrites
  1. a Ach, norepinephrine, epinephrine, dopamine
  2. b more K+ inside, more Na+ outside
  3. c thin, branched processes whose main function is to receive incoming signals; effectively increase surface area of neuron to increase ability to communicate with other neurons; small, mushroom-shaped dendritic spines further increase surface area
  4. d conducts impulses from receptors to CNS; sensory nerve fibers can be somatic (from skin, muscles, joints) or visceral (from organs within ventral body cavity)
  5. e occurs in myelinated axons; it's faster

5 Multiple choice questions

  1. region of communication
  2. nervous system outside the brain & spinal cord; responsible for communication btwn CNS & rest of body
  3. exterior of Schwann cell surrounding an axon in PNS
  4. carry impulse from peripheral receptors to CNS
  5. NT; synaptic cleft

5 True/False questions

  1. Integrationmonitors changes/events occurring in & outside the body (stimuli); cells that respond=receptors


  2. types of neuroglia & locationdepolarization, reverse polarization, repolarization, action potential


  3. autonomic nervous systemvoluntary; from CNS to muscles


  4. "synaptic bulb"rush of positively charged Na+ into cell, driven by concentration gradient & electrical gradient; inside of cell becomes more positive


  5. axonaxon plasma membrane=axolemma; surrounded by a myelin sheath, a wrapping of lipid which protects the axon and electrically isolates it, increases rate of AP
