Verified step by step guidance

Understand the basic components of the nervous system: The nervous system is composed of neurons, which have structures such as dendrites, axons, and cell bodies. Additionally, there are supporting structures like ganglia and myelin sheaths.

Define each structure: Dendrites are extensions of neurons that receive signals. Axons are long projections that transmit signals away from the cell body. Myelin sheaths are insulating layers around axons that increase signal transmission speed. Ganglia are clusters of neuron cell bodies found in the peripheral nervous system.

Identify the function of ganglia: Ganglia serve as relay points and processing centers in the peripheral nervous system. They contain many neuron cell bodies, which are crucial for processing information and transmitting signals.

Compare the structures: While dendrites and axons are parts of individual neurons, ganglia are collections of neuron cell bodies. Myelin sheaths are not involved in housing cell bodies but rather in insulating axons.

Conclude the correct answer: Based on the definitions and functions, ganglia are the structures that contain many cell bodies in the nervous system.
