Ganglion cells are nerve cells that form clusters, or ganglia, in the peripheral nervous system. These clusters house the cell bodies of neurons, which are the fundamental units of the nervous system responsible for transmitting information. Ganglion cells play a crucial role in relaying sensory and motor signals between the central nervous system (brain and spinal cord) and the rest of the body.

There are two main types of ganglia: sensory ganglia and autonomic ganglia. Sensory ganglia contain the cell bodies of neurons that carry sensory information from the body's periphery to the central nervous system. Examples include the dorsal root ganglia, which transmit touch, pain, and temperature information, and cranial nerve ganglia. Autonomic ganglia are part of the autonomic nervous system, which controls involuntary bodily functions such as heart rate, digestion, and breathing. These ganglia contain the cell bodies of neurons that connect the central nervous system to target organs like glands and smooth muscles.

The structure of a ganglion typically includes the neuron cell bodies, dendrites that receive signals, and axons that transmit signals away from the cell body. These axons can extend for long distances, forming nerves that connect the ganglion to the central nervous system or to effector organs. Ganglion cells are essential for a wide range of bodily processes, enabling us to perceive our environment, react to stimuli, and maintain vital internal functions.
