Like other parts of the nervous system, the sympathetic nervous system operates through a series of interconnected neurons. Sympathetic neurons are frequently considered part of the peripheral ...

Four Fun Facts About Your Peripheral Nervous System ... But did you know that parts of you that you thought were in your PNS—the light sensing retinas of your eyes—are actually brain tissue?

Once dismissed as “junk,” a group of RNA molecules has been found to help regrow damaged nerves in mice in new research. The discovery could unlock new ways to treat nerve injuries and even restore ...

“Our work unveils the ontogeny, evolution, and neuron size regulatory functions of PNS microglia,” said Dr. WU Zhisheng, first author of the study. Reference: Wu Z, Wang Y, Chen W wei, et al.

Glial cells are an integral part of the human nervous system. They help support and nourish nerve cells, or neurons. Several types of glial cells exist. Glial cells are the “glue” of the ...

Neuropathy is when nerve damage interferes with the functioning of the peripheral nervous system (PNS). When the cause can’t be determined, it’s called idiopathic neuropathy. The PNS carries ...

The parasympathetic nervous system (PSNS) is one of two major divisions of the larger autonomic system in your body. Its function is to keep the basic functions of your body working as they should ...
