Information from the sympathetic nervous system follows a different structural path than the parasympathetic nervous system. Which of the following accurately describes the flow of sympathetic nervous system information?
  • a)
    A sympathetic nerve originates in the middle of the spinal cord and has a long axon to the synapse of a second neuron. From the second cell, there is a short axon that goes to the target neuron.
  • b)
    A sympathetic nerve originates in the middle of the spinal cord and has a short axon to the synapse of another neuron. From the second cell, there is a long axon that goes to target neuron.
  • c)
    A sympathetic nerve originates in the brain stem and has a short axon to the synapse of another neuron. From the second cell, there is a long axon that goes to the target neuron.
  • d)
    A sympathetic nerve originates in the bottom of the spinal cord and has a long axon to the synapse of another neuron. From the second cell, there is a short axon that goes to the target neuron.
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Information from the sympathetic nervous system follows a different st...
In the sympathetic nervous system, the preganglionic neuron originates in the middle (intermediolateral) region of the spinal cord, specifically in the thoracic and lumbar segments. The preganglionic neuron has a short axon that extends from the spinal cord to the synapse of a second neuron in a sympathetic ganglion located outside the spinal cord. This synapse occurs in the sympathetic chain ganglia.
From the ganglion, the postganglionic neuron emerges with a long axon that extends to the target organ or tissue. The postganglionic axon is responsible for transmitting the sympathetic signals to the effector organs, such as the heart, blood vessels, or sweat glands.
Therefore, Option B accurately describes the flow of sympathetic nervous system information, with a sympathetic nerve originating in the middle of the spinal cord, having a short axon to the synapse of another neuron, and from the second cell, a long axon goes to the target neuron.
