They are essential and structural units of the nervous system. Neurons are electrically excitable cells that are specialized to receive and transfer information to various body sections. Let’s discuss neuron definition in a detailed manner. Interneurons are little nerve cells that carry information between distinct neurons in the body. On the other hand, the motor neurons send information from the brain to the muscles. Sensory neurons provide information to the brain from sensory receptor cells located throughout the body. Neurons occur in various forms and sizes, but they all help with information transmission. This can be accomplished physically as well as electrically. They deliver and receive messages to a variety of body parts. Neuronal cells are the building components of the nervous system. Invertebrates or neurons, also known as nerve cells, are the most basic and most extended cells in the human body.
