What are nerve ganglions give examples?

Answer 1

A ganglion is a cluster of nerve cells found in the peripheral and central nervous system.

The main components of the ganglion are a cell body called the somata and associated dendritic structures. Ganglia often connect with each other to form a complex network called the plexus.

In addition to the ganglion of the peripheral nervous system, there are also parts of the brain that contains a cluster of interconnected nuclei called the "basal ganglia" or "basal nuclei".

Basal ganglia are found in the cerebral cortex, thalamus and brainstem and is associated with several key functions including motor control, emotions, cognition and learning.
