A group of sympathetic ganglia represents a network of nerve cell clusters that play a role in the sympathetic nervous system. These ganglia are part of the autonomic nervous system and are involved in the fight or flight response, regulating processes like heart rate, digestion, and blood pressure.

What is the sympathetic chain of collateral ganglia?
The sympathetic chain of collateral ganglia is a series of ganglia located alongside the vertebral column that house cell bodies of sympathetic neurons. They play a role in coordinating the sympathetic nervous system's response to stress and regulating functions like heart rate, blood pressure, and digestion.
Is the sympathetic chain composed of collateral ganglia?
Yes, the sympathetic chain is composed of collateral ganglia. These ganglia are arranged in a chain-like structure along the spinal cord and play a crucial role in the sympathetic nervous system's function to regulate the body's stress response.
All of the following are sympathetic ganglia EXCEPT?

Based on the main neurotransmitters the sympathetic nervous system can be classified as what-?
These are motor neurons located in the ganglia of the PNS
Are sympathetic ganglia within a few centimeters of the CNS?
Yes, sympathetic ganglia are located near the spinal cord, within a few centimeters of the central nervous system. They are responsible for transmitting signals from the CNS to different parts of the body, controlling functions like heart rate and blood pressure.

Postganglionic fibers that innervate targets in the body wall or thoracic cavity originate on neurons within?
Postganglionic fibers that innervate targets in the body wall or thoracic cavity originate on neurons within the sympathetic chain ganglia (paravertebral ganglia) or prevertebral ganglia (e.g., celiac ganglion). These ganglia are part of the sympathetic division of the autonomic nervous system and play a role in coordinating the body's fight-or-flight responses.
What is a knot-like swelling in a nerve where the cell bodies of neurons are concentrated?
Paravertbral ganglia (aka sympathetic trunk ganglia)
What is the nerve supply of parathyroid gland?
Superior or middle cervical sympathetic ganglia
Based on the main neurotransmitters the sympathetic nervous system can be classified as what-?
These are motor neurons located in the ganglia of the PNS
Which sympathetic fibers form the splanchnic nerve?
Sympathetic fibers that originate from the spinal cord levels T5-L2 form the splanchnic nerves. These fibers pass through the sympathetic chain ganglia without synapsing and project to the abdominal and pelvic viscera to regulate their functions.
Are sympathetic ganglia within a few centimeters of the CNS?
Yes, sympathetic ganglia are located near the spinal cord, within a few centimeters of the central nervous system. They are responsible for transmitting signals from the CNS to different parts of the body, controlling functions like heart rate and blood pressure.
Is short preganglionic axons parasympathetic or sympathetic?
Short preganglionic axons are characteristic of the sympathetic nervous system. In the sympathetic division, these axons originate in the spinal cord and project to nearby ganglia, which are typically located close to the spinal cord. In contrast, the parasympathetic nervous system features long preganglionic axons that extend from the brainstem or sacral spinal cord to ganglia located near or within target organs.
Do other organisms have ganglia other than worms?
All vertebrates have ganglia of some sort, but there are many different types of ganglia, from dorsal and spinal to autonomic, basal, sympathetic, and other types. Humans have basal ganglia, which makes up a section of the brain.
What ramus branches that belong to the sympathetic nervous system?
The sympathetic nervous system branches include the sympathetic trunk and the splanchnic nerves. The sympathetic trunk contains the sympathetic ganglia, which are responsible for sending signals to various target organs in the body. The splanchnic nerves innervate the abdominal organs and play a role in regulating their function.
