Verified step by step guidance

Understand the role of autonomic ganglia in the autonomic nervous system. Autonomic ganglia are clusters of nerve cell bodies located outside the central nervous system (CNS) and are part of the peripheral nervous system (PNS). They are involved in transmitting signals between preganglionic and postganglionic neurons.

Recall the structure of the autonomic nervous system. It consists of two main divisions: the sympathetic and parasympathetic systems. Both divisions use a two-neuron chain to transmit signals: a preganglionic neuron (originating in the CNS) and a postganglionic neuron (located in the autonomic ganglia).

Identify the components found in autonomic ganglia. Autonomic ganglia contain the cell bodies of postganglionic neurons, which receive signals from preganglionic neurons and relay them to target organs or tissues.

Eliminate incorrect options based on anatomical knowledge: Axons of sensory neurons are not part of autonomic ganglia; they are associated with sensory pathways. Cell bodies of somatic motor neurons are located in the CNS, not in autonomic ganglia. Dendrites of skeletal muscle fibers are not part of the nervous system; they are part of muscle tissue.

Conclude that the correct answer is 'Cell bodies of postganglionic neurons,' as this is the primary component found in autonomic ganglia and aligns with their function in the autonomic nervous system.
