Neuron ( /ˈnjʊərɒn/ newr-on; also known as a neurone or nerve cell) is an electrically excitable cell that processes and transmits information through electrical and chemical signals. 

Neurons can also be influenced or stimulated by the electronic magneticfields that are peresent in one’s environment.

But it is also said;

That when the oral spoken words are released via the art of oral speech, the sound waves travel via the electronic magneticfields in form of frequency or sound waves,

when they enter the human body through the ears—then the process of stimulating the sensory neurones occurs. 

A chemical signal occurs via a synapse, a specialized connection with other cells. 

Neurons connect to each other to form neural networks.

Neurons are the core components of the nervous system, which includes the brain, spinal cord, and peripheral ganglia. 

A number of specialized types of neurons exist:

Sensory neurons – respond to touch, sound, light and numerous other stimuli affecting cells of the sensory organs that then send signals to the spinal cord and brain. 

Motor neurons – receive signals from the brain and spinal cord, cause muscle contractions, and affect glands. 

Interneurons – connect neurons to other neurons within the same region of the brain or spinal cord.

All neurons are electrically excitable, maintaining voltage gradients across their membranes by means of metabolically driven ion pumps, which combine with ion channels embedded in the membrane to generate intracellular-versus-extracellular concentration differences of ions such as sodium, potassium, chloride, and calcium

Neurons residing in ganglia of the head and body supply the central nervous system with information about the aforementioned external stimuli occurring to the body.
