Which glial cells form an epithelium that lines a fluid-filled passageway within the spinal cord and brain?

The correct answer to this is:

“the ependymal cells”

Glial cells are cells that sustain and protect the neurons in the peripheral and central nervous system. They estimate to take up about half the volume of the nervous system. One of the glial cells is the ependymal cells. They create a simple cuboidal to columnar epithelium which is known as ependyma.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
