The central nervous system is made up of the brain and spinal cord. ... Along its length, it connects with the nerves of the peripheral nervous system (PNS) that run in from the skin, ...

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 ...

The nervous system of an animal coordinates the activity of the muscles, monitors the organs, constructs and also stops input from the senses, and initiates actions. The nervous system of ...

A dermatome is a distinct area of your skin defined by its connection to one of 30 spinal nerves. We’ll explore more about both your spinal nerves and dermatomes, including a chart showing each ...

Peripheral nervous system (PNS): The PNS is made up of nerves that branch off from your CNS. Nerves are bundles of axons that work together to transmit signals.
