Overview
Overview
Our nervous system plays a vital role in how we think, feel, and act. Neurons, the basic building blocks of the body’s circuitry, receive signals through their branching dendrites and cell bodies and transmit electrical impulses down their axons. Chemical messengers called neurotransmitters traverse the tiny synaptic gap between neurons and pass on excitatory or inhibitory messages.
