therapeutic agents for the nervous system - pharm tech
| Question | Answer |
|---|---|
| Alheimer disease | AD; a progressive form of dementia that affects memory, thinking, and behavior |
| Attention deficit / hyperactivity disorder | ADHD; a psychological brain disorder that affects the ability to engage in quiet, passive activities or to focus one's attention; attributable to a neurotransmitter imbalance |
| Autonomic nervous system | ANS; the nervous system branch that carries out "automatic" body functions. It includes the sympathetic and parasympathetic systems |
| blood-brain barrier | BBB; a brain barrier that results from special permeability characteristics of capillaries that supply brain cells; the capillaries prevent certain solutes or chemicals from passing from the blood to the brain |
| Bradykinesia | slowed movement |
| Brainstem | a section of the brain consisting of the medulla oblongata, pons, and midbrain, which connect the forebrain and cerebrum to the spinal cord |
| Central nervous system | CNS; consists of the brain and spinal cord; it coordinates sensory and motor body function control |
| cerebellum | a structure posterior to the pons and medulla oblongata responsible for posture, balance, and voluntary muscle movement |
| cerebrospinal fluid | CSF; a continually produced and absorbed clear, watery fluid that flows in the brain ventricles around the brain surface and the spinal cord |
| epilepsy | a brain disorder marked by repeated seizures over time |
| extrapyramidal symptoms | EPS; often result from taking antipsychotic medications and include parkinsonism, dystonia, and tremors |
| hemorrhagic stroke | a stroke caused by a brain blood vessel rupture |
| homeostasis | the body's tendency to maintain stability, as with body temperature |
| insomnia | difficulty falling or staying asleep |
| ischemic stroke | a stroke caused by a brain blood vessel blockage |
| multiple sclerosis | MS; an autoimmune disorder that affects CNS nerves; it leads to hindered motor functions |
| Myasthenia gravis | a neuromuscular disorder leading to skeletal muscle weakness |
| neuron | the nervous system's basic building block and cell |
| Parasympathetic nervous system | PSNS; the nervous system division outside the brain and spinal cord |
| Parkinson disease | PD; a movement disorder with the classic symptoms of tremor, rigidity, bradykinesia, and postural instability |
| Peripheral nervous system | PNS; the nervous system division outside the brain and spinal cord |
| polyneuropathy | a neurological disorder that occurs when many nerves malfunction; it may include painful neuropathy |
| psychosis | a mental illness characterized by loss of contact with reality. Psychosis may be a true mental illness; due to an underlying medical condition (eg. dementia or drug withdrawal syndromes); or induced by medications, recreational drugs, or poisons |
| schizophrenia | a disorder characterized by inappropriate emotions and unrealistic thinking |
| somatic nervous system | the motor neurons of the peripheral nervous system that control voluntary actions of the skeletal muscles and provide sensory input (touch, hearing, sight) |
| Sympathetic nervous system | SNS; an autonomic nervous system division that activates during stress; the "fight or flight" response |
| tardive dyskinesia | TD; a type of dyskinesia (unwanted, involuntary rhythmic movements) recognized as a potential side effect of dopamine antagonists (eg. phenothiazines, metoclopramide); the symptoms may continue even after the offending drug is discontinued |
