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.
There are major nerve plexuses (off the spinal cord)
1. Cervical plexus - innervates the diaphragm
"The primary danger of a 'broken neck' is that the phrenic nerve may have been severed, leading to paralysis, cessation of breathing and death …"
2. Brachial plexus
1. Axillary nerve
2. Radial nerve
3. Median nerve
4. Musculocutaneous nerve
5. Ulnar nerve
These move arm and fingers
3. Lumbar plexus
Movement of legs
4. Sacral plexus
Movement of feet

What are the characteristics of ganglions?
Ganglions are noncancerous cysts filled with fluid that typically form near joints or tendons in the wrists, hands, or feet. They may appear as a smooth lump or bump under the skin and can vary in size. Ganglions are usually painless but can cause discomfort if they press on a nerve.
What neurotransmitter is used by most postganglionic sympathetic neurons?
At the effector end (nerve to effector organ junction) the transmitter is Nor Adrenaline. However, at the nerve-nerve junctions (ganglions) the transmitter is Acetyl Choline.
Explain why the dorsal root ganglions are larger in diameter than the dorsal root?
Dorsal root ganglia contain cell bodies of sensory neurons, which are larger and more complex structures compared to the dorsal root that mainly consists of nerve fibers. The ganglia need more space to accommodate the cell bodies and additional structures like satellite cells and glial cells, leading to their larger diameter compared to the dorsal root.
Some flatworms have clusters of nerve cells that control the nervous system each cluster is called?
Some flatworms have clusters of nerve cells called ganglia that control their nervous system. Ganglia are distributed throughout the body and help coordinate the flatworm's movements and responses to stimuli.
A knot like swelling in a nerve where the cell bodies of neurons are concentrated?
This is likely a ganglion, which is a cystic swelling that forms on a nerve sheath typically due to repetitive stress or irritation. Ganglions are often harmless and may resolve on their own or with simple treatments like monitoring, rest, or aspiration. However, if the ganglion causes pain or affects function, medical evaluation may be needed.

What prevention methods are there to avoid a ganglion?
Exercises that increase muscle strength and flexibility can prevent ganglions. Warming and cooling down before and after workouts may also decrease the rate of developing ganglions.

An automatic nerve response?
The automatic nerve response is from the system which controls the involuntary autonomous functions of the body. Breathing and heart beats are examples of these.
