Choose the incorrect statement about the somatic motor efferent division.

Wähle eine der folgenden:

  • 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.

Erklärung

1

Choose the correct statements about the autonomic efferent motor division.

Wähle eine oder mehr der folgenden:

  • 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

Erklärung

Frage 5 von 10

1

Choose the false statement about the autonomic nervous system.

Wähle eine der folgenden:

  • 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.

Erklärung

Frage 6 von 10

1

Wähle eins der folgenden:

  • WAHR

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Frage 8 von 10

1

Choose the correct statement.

Wähle eine der folgenden:

  • 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.

Erklärung
