Where are the collateral ganglia?
sveta [45]

The collateral ganglia are found in abdominal aorta.

What are collateral ganglia?

The prevertebral ganglia, also known as collateral ganglia, are located anterior to the vertebral column and receive input from central sympathetic neurons as well as splanchnic nerves. They are regarded as a component of the enteric nervous system and are connected to the control of abdominal organs.

The sympathetic ganglia known as collateral ganglia, sometimes known as prevertebral ganglia, are located in between the sympathetic chain and the organ of supply. The preganglionic sympathetic fibers that supply the viscera in the abdomen and pelvis relay at this location.
