Name the types of cells in the nervous system and their functions.
Glial cells support cell function. Neurons - communication
The nerve cell that carries impulses from a sensory receptor to the brain or spinal
The nerve cell that transmits impulses from the brain or spinal cord to a muscle or gland.
The connections between sensory and motor neurons are called _.
How is information transmitted in the nervous system (at the cellular level)?
Electrical energy moves down towards the muscles, turns into chemical energy between cells, then goes back into electrical energy. This happens at synaptic cleft.

Name the ventricles in the brain.
2 lateral ventricles, third ventricle, fourth ventricle
What does the CSF do?
