| Question | Answer |
|---|---|
| Three protective membranes surrounding the brain and spinal cord | Meninges |
| Microscopic fiber that carries the nervous impulse along a nerve cell | Axon |
| A large, interlacing network of nerves | Plexus |
| Branching fiber that is first part of a neuron to receive a nervous impulse | Dendrite |
| Protective fatty tissue that surrounds the axon of a nerve cell | Myelin sheath |
| Collection of spinal nerves below the end of the spinal cord | Cauda equine |
| Glial cell that produces myelin | Oligodendroglia |
| outer most region of the largest part of the brain; composed of gray matter | Cerebral cortex |
| Carries messages toward the brain from receptors | Sensory nerve |
| Essential cell of the nervous system; a neuron | Parenchymal cell |
| Innermost meningeal membrane | Pia mater |
| Elevations in the cerebral cortex | Gyri |
| Acetylcholine is an example of this chemical released into a synapse | Neurotransmitter |
| Contains cerebrospinal fluid | Subarachnoid space |
| Slow movement | Bradykinesia |
| Increased nervous sensation | Hyperperesthesia |
| Seizure of sleep | Narcolepsy |
| Movements and behavior are not purposeful | Apraxia |
| Fainting | Syncope |
| Burning pain | Causalgia |
| No coordination | Ataxia |
| Slight paralysis in half of the body | Hemiparesis |
| Destruction of the myelin sheath; replacement by plaques of hard scar tissue | Multiple sclerosis |
| Sudden, transient disturbances of brain function marked by seizures | Epilepsy |
| Loss of muscle strength; breakdown of acetylcholine, a neurotransmitter | Myasthmia gravis |
| Degeneration of nerves in the brain leading to tremors, shuffling gait and muscle stiffness (mask like facial expression); dopamine is deficient in the brain | Parkinson's disease |
| Deterioration of mental capacity (dementia) beginning in middle age; cerebral cortex atrophy, microscopic neurofibrillary tangles | Alzheimer's disease |
| Unilateral facial paralysis | Bell's palsy |
| Relieving but not curing | Palliative |
| Major convulsive epileptic seizure | Tonic-clonic seizure |
| Peculiar symptoms appearing before more definite symptoms | Aura |
| Malignant brain tumor of immature glial cells | Glioblastoma multiforme |
| Interruption of blood supply to the cerebrum | Transient ischemic attack |
| Minor form of epileptic seizure | Absence seizure |
| Blockage | Occlusion |
| Neurotransmitter | Dopamine |
