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.
What is the chain ganglia part of?
The chain ganglia are part of the autonomic nervous system. They are clusters of nerve cell bodies located along the spinal cord and are involved in the regulation of involuntary bodily functions such as heart rate, digestion, and breathing.
All of the following are sympathetic ganglia EXCEPT?

What does a group of Sympathetic ganglia represent?
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.
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.
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 are the fibers that enter and leave the sympathetic chain without synapsing form structures are called?
They are called splanchnic nerves. These nerves carry preganglionic fibers to the collateral ganglia where they synapse with postganglionic neurons.
What is the chain ganglia part of?
The chain ganglia are part of the autonomic nervous system. They are clusters of nerve cell bodies located along the spinal cord and are involved in the regulation of involuntary bodily functions such as heart rate, digestion, and breathing.
Which of the following ganglia is not a collateral ganglion?
cervical
Why is the sympathetic chain also referred to as the paravertebral chain?
The sympathetic chain is also called the paravertebral chain because it runs parallel to the vertebral column. It consists of a series of ganglia connected by nerve fibers that regulate involuntary functions in the body. This chain plays a crucial role in the fight-or-flight response.

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
