ANATOMY

Detailed explanation-1: -Glia outnumber neurons in some parts of the brain, but neurons are the key players in the brain. Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system.

Detailed explanation-2: -Nerve cells are also called neurons. Neurons are present all over your body, especially in your brain and spinal cord. Nerves, together with your brain and spinal cord, are the foundation of your nervous system.

Detailed explanation-3: -Action potentials are propagated along the length of axons and are the fundamental signal that carries information from one place to another in the nervous system.

Detailed explanation-4: -These connections occur at junctions known as synapses. The synapses allow electrical and chemical messages to be transmitted from the neuron to the other cells in the body.
