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 |

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 |
