Nervous System
| Question | Answer |
|---|---|
| Neuron | a nerve cell |
| Neurotransmitter | a chemical produced by the body to permit the nerve impulse to trave from one nerve cell to the next nerve cell |
| Central Nervous System (CNS) | the brain and spinal cord |
| Peripheral Nervous System (PNS) | branches of nerves which extend from the brain and spinal cord, traveling throughout the body |
| Autonomic Nervous System (ANS) | a part of the peripheral nervous system which controls the involuntary (or automatic) functions of the body |
| Cerebrum | the largest part of the brain- responsible for emotions, voluntary muscle movement, sensory interpretations, memory, speech, and many other body functions |
| Brain stem | the portion of the brain that ies at the top of the spinal cord. Ir is responsible for controlling many involuntary functions such as pulse, respiration, and blood pressure |
| Cerebrospinal Fluid | "CSF" - a fluid which circulates around the brain and spinal cord to cushion and protect them |
| Meninges | protective membrane layers around the brain and spinal cord |
| Epilepsy | body's response to the release of excess brain waves (too much activity) from a specific area of the brain |
| Seizure | abnormal or unusual body movements or responses sdue to epilepsy |
| Stroke | "CVA" or brain attack- cerebrovascular accident |
| Aphasia | not able to speak |
| Aphagia | not able to swallow |
| Paralysis | inability of the body to move, usually due to damage to the nerves which supply specific muscles |
| Paraplegia | paralysis that affects the lower half of the body |
| Quadriplegia | paralysis that affects all four limbs of the body |
| Hemiplegia | paralysis that affects either the left or right half of the body |
| Dementia | deterioration of the brain's ability to function due to various disorders that cause damage to brain cells |
| Sundowning | a characteristic of Alzheimer's Disease where the person becomes increasingly confused and agitatd in the late afternoon and early evening |
| Peripheral Neuritis | irritation of peripheral nerves due to injury or disease. the patient may experience numbness, burining sensations, or discomfort |
| Multiple Sclerosis | occurs when the protective covering (myelin sheath) over the nerve fibers deteriorate, resulting in interference with the nerve impulse transmission to the muscles and subsequent lack of muscle control |
| Parkinson's Disease | a lack of production of the chemical Dopamine within the brain. This chemical is necessary for the control of voluntary muscles. An nsufficient amount results in uncontrollable tremors of the muscles. |
| Transident Ischemic Attack | "TIA"- temporary lack of blood flow to the brain, which causes stroke-like symptoms. |
| Cerebral Aneurysm | a wekness in the wall of a blood vessel within the brain. The danger is that the area may rupture, causing internal bleeding. |
| Cerebral Vascular Accident | "CVA"- "stroke", "brain attack": occurs when an area of the brain does not receive enough blood flow due to blockage of an artery, or a ruptured blood vessel (aneurysm) |
| Alzheimer's Disease | a condition with severe memory impairment due to a build-up of abnomral protein deposits in the brain |
