Explanation

Question 2 of 10

1

Choose the incorrect statement about the somatic motor efferent division.

Select one of the following:

  • It effects only skeletal muscle.

  • There is only one axon between the CNS and effector, and it is unmyelinated.

  • The neuronal cell body is within the spinal cord.

Explanation

Question 3 of 10

1

One neuron can never innervate more than one muscle cell.

Select one of the following:

  • True
  • False

Explanation

Question 4 of 10

1

Choose the correct statements about the autonomic efferent motor division.

Select one or more of the following:

  • There are 2 neurons between the CNS and the effector.

  • Both neurons have their cell bodies in the CNS.

  • Both neurons have their axons in the PNS.

  • Effectors include smooth muscle, cardiac muscle, glands, and adipose tissue

Explanation

Question 5 of 10

1

Choose the false statement about the autonomic nervous system.

Select one of the following:

  • The preganglionic autonomic motor neuron is myelinated.

  • The postganglionic neuron is unmyelinated.

  • The neurotransmitter released at the synapse of the preganglionic neuron to the postganglionic neuron can be ACh or norepinephrine.

  • The neurotransmitter released at the synapse of the postganglionic neuron to the effector can be ACh or norepinephrine.

Explanation

Question 6 of 10

1

Norepinephrine is a more concentrated neurotransmitter than noradrenaline.

Select one of the following:

  • True
  • False

Explanation

Question 7 of 10

1

The autonomic nervous system has one afferent pathway, and two efferent pathways.

Select one of the following:

  • True
  • False

Explanation

Question 8 of 10

1

Choose the correct statement.

Select one of the following:

  • The parasympathetic nervous system can also be called the thoracolumbar nervous system.

  • The sympathetic nervous system can also be called the craniosacral nervous system.

  • The preganglionic neuron of the sympathetic division is short, while the postganglionic neuron is long.

  • The postganglionic neuron of the parasympathetic nervous system is long and synapses in the chain ganglia.

Explanation

Select one of the following:

  • True
  • False
