Information in the form of light, sound waves, odors, tastes, or contact with objects, is gathered from the environment by specialized cells called sensory neurons. In between sensory neurons and motor neurons come the interneurons- neurons that lie entirely within the cns. Local interneurons form circuits with nearby neurons and analyze small pieces of info. Relay interneurons connect circuits of local interneurons in one region of the brain and with those in other regions. 2 basic divisions in ns: cns- consists of the parts encased by the bones of the skull and spinal column: Brain and spinal cord: pns- found outside these bones and consists of the nerves and most sensory organs, cells of the nervous system.
