Document Summary

Have receptors to detect changes in the environment. Processes the sensory input and decides if response is required. Telling body what to do during a response. Sends down a motor message to respond to the stimulus. Central nervous system (cns): made up of brain and spinal cord. Neurons are grouped into sensory, motor, and interneurons. Peripheral nervous system (pns): outside of the brain and spinal cord. Has 2 divisions of neurons, sensory (afferent) and motor (efferent) Neurons are the functional unit of the nervous system. Responsible for receiving information from receptors and transmitting that to the cns. It is subdivided into sensory somatic (body) example: touch/pain/pressure. And visceral (organs) - example: blood vessels, digestive/respiratory organs. Responsible for transmitting motor impulses from cns to muscles or glands. Responsible for directing information towards the body. Responsible for directing information away from the body. Regulate what substance comes in contact with the neuron. Myelin insulates the axon and is composed of fat.
