Pituitary Gland

A pea-sized gland located at the base of the brain, often termed the "master gland," because it controls various hormonal functions of other endocrine glands.

Absolute Refractory Period

The period immediately following an action potential during which a neuron is incapable of firing another action potential, no matter how strong the stimulus.

Neural Impulses

Neural impulses, also known as action potentials, are the electrical signals that travel along neurons, transmitting messages throughout the nervous system.
