What are glial cells and what do they do?


Satellite cells

Satellite cells get their name from the way they surround certain neurons, with multiple satellites forming a sheath around the cell surface. We are beginning to learn about these cells, but many researchers believe that they are similar to astrocytes.

However, satellite cells are found in the peripheral nervous system, unlike astrocytes, which are found in the central nervous system. The main purpose of satellite cells is to regulate the environment around neurons to maintain the balance of chemicals.

Neurons that have satellite cells form the gangilla, which is a collection of nerve cells in the autonomic nervous system and sensory systems. The autonomic nervous system regulates your internal organs and your sensory system is what allows you to see, hear, smell, touch, touch, and taste.

Satellite cells provide nutrition to neurons and absorb heavy metal toxins such as mercury and lead so they do not damage neurons. Like microglia, satellite cells detect and respond to injury and inflammation. However, its role in repairing cell damage has not yet been adequately studied.

They are also believed to help transport various neurotransmitters and other substances, including:

Satellite cells are associated with chronic pain, including peripheral tissue damage, nerve damage, and increased systemic pain (hyperalgesia) that can result from chemotherapy.

Much of what we know, believe, or suspect about glial cells is new knowledge. These cells help us understand how the brain works and what happens when something doesn't work as it should.

There is no doubt that we still have a lot to learn about glia and we are likely to receive new treatments for many diseases as our knowledge increases.
