Questions in this quiz (10)

  1. 1The somatic nervous system controls efferent, [blank_start]voluntary[blank_end] motor control, and afferent sensory information [blank_start]we are aware of[blank_end].
    Autonomic efferent muscle control is [blank_start]involuntary and unconscious[blank_end], and afferent sensory information [blank_start]we are unaware of[blank_end].
    1. Avoluntary
    2. Bwe are aware of
    3. Cinvoluntary and unconscious
    4. Dwe are unaware of
  2. 2Choose the incorrect statement about the somatic motor efferent division.
    1. AIt effects only skeletal muscle.
    2. BThere is only one axon between the CNS and effector, and it is unmyelinated.
    3. CThe neuronal cell body is within the spinal cord.
  3. 3One neuron can never innervate more than one muscle cell.
    1. ATrue
    2. BFalse
  4. 4Choose the correct statements about the autonomic efferent motor division.
    1. AThere are 2 neurons between the CNS and the effector.
    2. BBoth neurons have their cell bodies in the CNS.
    3. CBoth neurons have their axons in the PNS.
    4. DEffectors include smooth muscle, cardiac muscle, glands, and adipose tissue
  5. 5Choose the false statement about the autonomic nervous system.
    1. AThe preganglionic autonomic motor neuron is myelinated.
    2. BThe postganglionic neuron is unmyelinated.
    3. CThe neurotransmitter released at the synapse of the preganglionic neuron to the postganglionic neuron can be ACh or norepinephrine.
    4. DThe neurotransmitter released at the synapse of the postganglionic neuron to the effector can be ACh or norepinephrine.
  6. 6Norepinephrine is a more concentrated neurotransmitter than noradrenaline.
    1. ATrue
    2. BFalse
  7. 7The autonomic nervous system has one afferent pathway, and two efferent pathways.
    1. ATrue
    2. BFalse
  8. 8Choose the correct statement.
    1. AThe parasympathetic nervous system can also be called the thoracolumbar nervous system.
    2. BThe sympathetic nervous system can also be called the craniosacral nervous system.
    3. CThe preganglionic neuron of the sympathetic division is short, while the postganglionic neuron is long.
    4. DThe postganglionic neuron of the parasympathetic nervous system is long and synapses in the chain ganglia.
  9. 9The sympathetic chain ganglia has 21-23 pairs.
    1. ATrue
    2. BFalse
  10. 10There are [blank_start]3[blank_end] main collateral ganglia, which contain [blank_start]preganglionic[blank_end] axons that did not make synapses in [blank_start]chainganglia[blank_end].
    1. A3
    2. B2
    3. Cpreganglionic
    4. Dpostganglionic
    5. Echain ganglia
    6. Ftheir effectors

Information

Description
