Explanation:
Ganglia are aggregations of neuronal somata and are different in structure and size.
Parasympathetic ganglia are the autonomic ganglia of the parasympathetic nervous system. They are involuntary and act alongside the sympathetic nervous system in order to regulate body homeostasis. They are a division of efferent nerve fibers and ganglia of the autonomic nervous system. They are located near or within the organs in which they innervate.
