Makes connections with other cells and allows the neuron to talk with other cells.

Neurons have different shapes depending on their function.

Carries signals from the central nervous system to the outer parts of the body.

Connects various neurons within the brain and the spinal cord.

Simplest type of neural pathway.

Individual neurons linked together that form a net around the entire brain.

Localized collections of neuronal cell bodies that control sensory and motor functions.
