It is the group of ganglion to connections of same ganglion for not spaces to the nervous system.. !

The correct answer is option 'c) Ganglia'.

Ganglia are the network of nerve centers in the autonomic nervous system.

The autonomic nervous system (ANS) is a division of the peripheral nervous system that controls involuntary bodily functions, such as heart rate, digestion, and breathing. It is responsible for regulating and maintaining homeostasis in the body.

Ganglia are clusters of nerve cell bodies located outside the central nervous system. They are an important part of the autonomic nervous system as they serve as relay stations where nerve impulses are transmitted between different neurons.

- Autonomic Nervous System (ANS):
The autonomic nervous system consists of two major divisions: the sympathetic nervous system and the parasympathetic nervous system. These two divisions work together to regulate various bodily functions.

- Sympathetic Nervous System:
The sympathetic nervous system is responsible for the body's fight or flight response. It prepares the body for action in response to perceived threats or stress. During this response, the sympathetic nervous system increases heart rate, dilates blood vessels, and redirects blood flow to the muscles.

- Parasympathetic Nervous System:
The parasympathetic nervous system is responsible for the body's rest and digest response. It helps regulate bodily functions during periods of rest and relaxation. The parasympathetic nervous system slows heart rate, constricts blood vessels, and promotes digestion.

- Ganglia in the Autonomic Nervous System:
Ganglia are an integral part of the autonomic nervous system. They are located outside the central nervous system and are found along the pathways of nerves. Ganglia contain clusters of nerve cell bodies called ganglion cells.

- Function of Ganglia:
Ganglia serve as relay stations in the autonomic nervous system. They receive incoming nerve impulses from sensory neurons and transmit them to other neurons. Ganglia also integrate and process these signals before sending them to their target organs or tissues.

- Types of Ganglia:
There are two types of ganglia in the autonomic nervous system: sympathetic ganglia and parasympathetic ganglia. Sympathetic ganglia are located close to the spinal cord, while parasympathetic ganglia are located near or within the target organs.

In conclusion, ganglia are the network of nerve centers in the autonomic nervous system. They play a crucial role in relaying and processing nerve impulses within the autonomic nervous system, helping to regulate involuntary bodily functions.
