| acetylcholine | compond resleased at autonmic nerve ending that fuctions in the transmission of nerve impluses. |
| autonomic nervous system | a division of the periopheral nervous system consisting for motor fibers from the brain and spinal cord that serve the internal organs of the body; not under voulntary control |
| axon | along thin fiber that carries nerve implues away from the cell body of a neuro |
| central nervous system | the division of the nervous system that includes the brain and the spinal cord |
| cerebrum | the lagest part of the human brain |
| cerbellum | part of the human brain below the rear part of the cerbrum; coordinates voluntary movement |
| cerbral palsy | group of birth disorders chartacterized by distarbances of the motor functions |
| cyton | part of the nerve that contains the nuclease and cytoplasm(also called cellbody) |
| dendrite | the short,branch parts of a neuron specialized for receiving nerve impluses and transmitting them to the cell bodies |
| effertor | a muscle or gland,responds to a stimulus |
| ganglion | a group of cells bodies and interneurosus that switch,relay and coordinate nerve impluses |
| impluse | messages carried by the nerve cells of a nerveouse system,region of electrial and chemial changes that pass along the cell membrane of the neuron |
| sensory neuron | nerve cells that carry impluse from receptors toward the spinal cord and the brain |
| somatic nervous system | the division of the peripheral nervouse system that contains sensory and motor neurons that connect the central nervouse system to skeletal muscles,skin, and the sense |
| spinal cord | the cord of nervous tissue in vertebrae that extends down from the brain,running though the vertebrae of the spinal cord |
| stimulus | any factors that cause a recptor to trigger impluses in a nerve pathway, resulting in a change of activity |
| stroke | a result of severe disturbance of blood flow to the brain |
| synapse | the region where nerve impluses pass from one nerve to another |
| terminal branches | found at the end of a neuron |
| ventral nerve cord | hollow and tubular cord that cord that runs along the ventral (back) length of the animal |
| vertebra | the bones of the spinal column that surrounds and protects the spinal cord |
