Structure of a typical neuron
Neuron (peripheral nervous system)

A neuron (/ˈnjʊərɒn/ NYEWR-on or /ˈnʊərɒn/ 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. These signals between neurons occur via synapses, specialized connections with other cells. Neurons can connect to each other to form neural networks. Neurons are the core components of the brain and spinal cord of the central nervous system (CNS), and of the ganglia of the peripheral nervous system (PNS).

There are several types of specialized neurons.Sensory neurons respond to stimuli such as touch, sound or light and all other stimuli affecting the 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 to cause muscle contractions and affect glandular outputs.Interneurons connect neurons to other neurons within the same region of the brain, or spinal cord in neural networks.
