Neurotransmitters

Chemical substances that transmit signals across a synapse from one neuron to another, facilitating neuronal communication.

Long nerve fibers that are part of neurons, responsible for transmitting electrical impulses away from the neuron's cell body.

Action Potentials

Brief electrical impulses that are the means by which information is transmitted along neurons and across synapses.

Endorphins

Endorphins are natural chemicals in the body that interact with brain receptors to reduce pain perception and lead to feelings of euphoria, often referred to as the body's "feel-good" hormones.
