Question

autonomic nervous system organization
which innervates target cells or organs of the autonomic nervous system (ans)?
postganglionic neuron
preganglionic neuron
autonomic ganglion
somatic motor neuron

Explanation:

• Postganglionic neuron: In the autonomic nervous system, postganglionic neurons extend from the autonomic ganglia to the target cells or organs. They release neurotransmitters (such as norepinephrine in the sympathetic division and acetylcholine in the parasympathetic division) that directly act on the target tissues.
• Preganglionic neuron: Preganglionic neurons originate from the central nervous system (brain or spinal cord) and synapse with postganglionic neurons in the autonomic ganglia. They do not directly innervate the target cells or organs of the ANS.
• Autonomic ganglion: It is a cluster of neuron cell bodies (where preganglionic neurons synapse with postganglionic neurons). It is not a neuron that innervates the target cells or organs.
• Somatic motor neuron: These neurons are part of the somatic nervous system, which controls voluntary muscle movements (such as skeletal muscle). They are not involved in innervating the target cells or organs of the autonomic nervous system.

Answer:

Postganglionic neuron
