| Term | Definition |
| sensory input | any electrical impulse sent from the eyes, ears, nose, tongue or skin to the central nervous system (brain and spinal cord) |
| integration | information from the sensory organs is interpreted motor output: the response generated from the interpretation of sensory input. |
| Voluntary movement | skeletal muscle |
| Involuntary movement | cardiac & smooth muscle |
| CNS function | Coordinates all activities of the body by receiving and transmitting messages throughout the body |
| Right side | controls the left side of body, music/art (creativity) ,intuition, emotions, face recognition, subjectivity |
| Left side | controls the right side of body, numbers/math/scientific skills, language, logic/reasoning, objectivity |
| PNS function | Receives and transmits messages to and from all parts of the body |
| PNS | all nerves outside the brain and spinal cord |
| CNS | brain and spinal cord |
| occipital lobe | eyesight/vision |
| temporal lobe | smell and hearing, language, factual and visual memory frontal lobe - controls movement, personality and emotion, problem solving, and speech |
| parietal lobe | receives and interprets sensory impulses to touch, pain, pressure, and temp |
| cerebrum | judgment, memory, association & critical thinking, highest levels of thought (lobes of the brain) |
| diencephalon | posterior part of the forebrain with three endocrine glands |
| thalamus | sensory “traffic director” |
| hypothalamus | controls HR, BP, body temp, hormones, hunger, thirst, digestion |
| pineal | circadian rhythm |
| Brain stem includes | pons, midbrain, medulla oblongata |
| Spinal cord function | transmits nerve impulses between the brain, limbs, and lower part of the body |
| What protects the spinal cord | CSF and spinal column |
| what is white matter | made of nerve fibers |
| what is gray matter | made of cell bodies |
| nerves function | Receives and transmits messages to and from all parts of the body |
| Neuron | basic cell of the nervous system (nerve cell) |
| Afferent | sensory nerves(example: touching a hot object is sensed by the brain as hot to the touch) |
