Question | Answer |
---|---|
smallest part of nervous system | Neuron |
bundles of cell bodies | Ganglions |
Neuron extensions that recieve electrical impulses | Dendrites |
part of neuron that processes electrical impulses | cell body |
part of neuron that conducts impulses | Axon |
Largest section of brain | Cerebrum |
Controls appetite | hypothalamus |
controls breathing | medulla oblongata |
controls muscle function | cerebellum |
Parkinsons has an imbalance of these | Dopamine, acetylcholine |
relays messages from outside to cns | Somiatic system |
what is SMR | Skeletal Muscle Relaxant |
Cholinergic agent | Mestinon |
SMR | Flexeril, Soma, Chlorzoxazone |
Treat myasthenia gravis | Neostigmine, Mestinon |
Progressive degenerative brain cond. | Alzheimers |
treat parkinsons | Symmetrel, Benztropine, eldepryl |

responds in stressful situations | sympathetic |
feed-n-breed | parasympathetic |
Mimic sympathetic nervous system | adrenergics |
take w/food, milk, no alcohol, d/d | Aux labels for SMR's |
direct acting muscle relaxants depress | calcium |
centrally acting muscle relaxants depress | CNS |
transmits messages from peripheral area to CNS | afferent |
transmits messages from CNS to peripheral area | efferent |
where neurotransmitters travel from one neuron to the next | synapse |
white matter | bundles of nerve fibers (myelinated axons) |
Gray matter | neuron cell bodies, dendrites |
treat epilepsy | anticonvulsants |
treat alzheimers | cholinesterase inhibitors |
treat multiple sclerosis | autoimmune stimulants |
goal of parkinsons treatments | increase dopamine |
cholinergics | treat myasthenia gravis |
