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 serve as relay points for autonomic signals traveling from the CNS to target organs.

Recall the structure of the autonomic nervous system. It consists of two main types of neurons: preganglionic neurons (originating in the CNS) and postganglionic neurons (located in autonomic ganglia). Preganglionic neurons synapse with postganglionic neurons in the ganglia.

Eliminate incorrect options based on anatomical knowledge: Dendrites of interneurons are typically found within the CNS, not in autonomic ganglia. Cell bodies of somatic motor neurons are located in the spinal cord and are part of the somatic nervous system, not the autonomic system. Axon terminals of sensory neurons are involved in sensory pathways and are not part of autonomic ganglia.

Focus on the correct option: Autonomic ganglia contain the cell bodies of postganglionic neurons. These neurons receive signals from preganglionic neurons and transmit them to target organs such as smooth muscle, cardiac muscle, or glands.

Summarize the key concept: Autonomic ganglia are essential relay stations in the autonomic nervous system, containing the cell bodies of postganglionic neurons that play a critical role in transmitting autonomic signals to effector organs.
