A chemical signal occurs via a [[Synapse|synapse]], a specialized connection with other cells. Neurones connect to each other to form neural networks. Neurones are the core components of the nervous system, which includes the brain, spinal cord, and peripheral ganglia. | ||
A number of specialized types of neurones exist. Sensory neurones 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 neurones receive signals from the brain and spinal cord, cause muscle contractions, and affect glands. Interneurones connect neurones to other neurones within the same region of the brain or spinal cord. | A number of specialized types of neurones exist.
