5 Matching questions

  1. type C fibers
  2. two major efferent systems
  3. depolorization, repolarization, and hyperpolarization
  4. synaptic delay
  5. nissl body
  1. a
  2. b -dense area of RER and ribosomes (produce neurotransmitters)
    -make neural tissue appear gray (gray matter)
  3. c somatic nervous system (SNS) -
    autonomic (visceral) nervous system (ANS) -
  4. d -unmyelinated
    -small diameter
    -slow speed
    -carry slower information
    -e.g. involuntary muscle, gland controls
  5. e -fewer synapses mean faster response
    -reflexes may involve only one synapse

5 Multiple choice questions

  1. -transmembrane potential is most affected at point of stimulus and then diminishes with distance
    -spreads passively
    -may involve either depolarization or hyperpolarization
    -the stronger the stimulus the greater the effect
  2. resting potential - transmembrane portential of resting cell
    graded potential - temporary, localized change in resting potential
    action potential - electrical impulse; produces by graded potential; propagates along surface of axon to synapse
    synaptic activity - releases neurotransmitters at presynaptic membrane; produces graded potentials in postsynaptic membrane
    information processing - response (integration of stimuli) of postsynaptic cell
  3. -brain
    -spinal cord
    -sensory receptors of sense organs
    -nerves connect nervous system with other systems
  4. -all plasma (cell) membranes produce electrical signals by ion movements
    -transmembrane potential is particularly important to neurons
  5. presynaptic cell - neuron that sends message
    postsynaptic cell - cell that receives message
    synaptic cleft - small gap that separates the presynaptic membrane and the postsynaptic membrane

5 True/False questions

  1. events in the functioning of a cholinergic synapse-action potential arrives, depolarizes synaptic knob
    -calcium ions enter synaptic knob, trigger exocytosis of ACh
    -ACh binds to receptors, depolarizes postsynaptic membrane
    -AChE breaks ACh into acetate and choline


  2. temporal and spatial summation


  3. synaptic terminals-fewer synapses mean faster response
    -reflexes may involve only one synapse


  4. neuroglandular junctionsynapse between neuron and gland


  5. astrocytesalso, glial cells
    cells that support and protect neurons
