Definitions:

Resting Potential

The voltage difference between the inside and the outside of a neuronal membrane when the neuron is not firing.

Nerve Impulses

Electrical signals that travel along the dendrites and axons of neurons, enabling communication within the nervous system.

Unmyelinated Axons

Refer to nerve fibers that lack a myelin sheath, resulting in slower transmission of nerve impulses compared to myelinated axons.

Gray Matter

The regions of the brain and spinal cord that consist primarily of neuronal cell bodies and are involved in muscle control and sensory perception.
