Which nervous system structure contains a cluster of cell bodies situated in the PNS?

A cluster of cell bodies situated in the peripheral nervous system (PNS) is referred to as a ganglion. Ganglia serve as important relay points in the nervous system, where synapses occur among neurons. They can be found throughout the PNS and are involved in processing and transmitting information to and from different parts of the body.

In contrast, a nucleus refers to a similar cluster of cell bodies but is found in the central nervous system (CNS). Tracts are bundles of axons within the CNS that have a specific function or destination, while afferent neurons are a type of neuron that carry sensory information toward the CNS, rather than being a structure that contains cell bodies. Hence, the distinction of structures based on their location in either the PNS or CNS is crucial for understanding their roles and functions within the nervous system.
