The basic unit of the nervous system and can be grouped into three general categories. Sensory: conduct information toward the brain and spinal cord and extend from sensory receptors that gather information about the conditions within and around our bodies. Interneuron: located between sensory neurons and motor neurons and only in the brain and spinal cord where they interoperate sensory signals then decides the appropriate response. Motor neuron: carry information away from the brain and spinal cord to an effector either a muscle (contract) or a gland (secrete products) as a response from the sensory or interneuron. Messenger of neurological information from one well to the other: acetylcholine. A chemical released by nerve cells to send signals to other cells. Helps regulate emotions and used in pathways that control complex movement.
