A _______________ is a drug that causes temporary paralysis by blocking the transmis- sion of nerve stimuli to the muscles. neuromuscular blocker skeletal muscle relaxant
Which neurotransmitter is released into the spinal cord (from first order to second order neuron) during a painful stimulus? acetylcholine serotonin norepinephrine glutamate substance P 14 F
Which of the statements about neurotransmitters given below is incorrect? О а. Orexin-producing cells in the locus querulous of the pons activate many different areas of the brain including the cerebral cortex, hippocampus, thalamus, cerebellum, and the pons and medulla as well. b. Blocking acetylcholine appears to reduce arousal levels, while procedures designed to increase acetylcholine production increase signs of arousal. Acetylcholine increases the general arousal of the cortex O C. Research has shown that Seratonin cells are most active during waking and decrease during sleep. In addition, serotonin seems to facilitate automatic behaviors such as chewing, pacing, or grooming.
Good morning Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the importance of sodium and calcium channels on a neuron and and the reasons why action potentials do not occur when these channels are inhibited. Be sure to include the phases of an action potential, the channels involved, and the importance of an action potential. Thank you
The form of chronic pain most associated with low serotonin and norephinephrine is: 1. chronic inflammatory pain 2. fibromyalgia 3. chronic neuropathic pain
NMDA receptors are responsible for potentiating transmission at the spinal cord 1. serotonergic and noradrenergic synapse 2. glutamatergic synapse 3. noradrenergic synapse only 4. serotonergic synapse only
i s the same as cholinergic, producing the effect of acetylcholine or an agent that mimics acetylcholine
List the various drugs classified as adrenergic agonists or sympathomimetics
Parkinson's disease affects the cerebral basal ganglia, resulting in tremors in limbs, slowness in beginning and completing movements, and other abnormalities of muscle control. Explain what the root cause of Parkinson's disease is (where, what is happening and what symptoms are seen). A treatment option is Dopamine, that usually fails. Propose a reason why this treatment fails. Propose a biomedical device intervention that you could use to control symptoms and how it works.
1. Choose (place an X) whether the characteristic applies to the Nervous System or Endocrine System (or both) Characteristic Action is generally brief (lasting milliseconds). Action generally lasts longer (seconds to days). Mediator molecules delivered to target by bloodstream. Action potentials trigger release of mediator molecules at synapse with target. Target cells require specific protein receptor for mediator molecule. Stimulates skeletal muscle contractions. Influence is much broader; will regulate virtually all types of body cells. Controls growth & development and regulates reproductive systems. Maintains internal environments (homeostasis) Nervous Endocrine Mediator molecules include acetylcholine, glutamate, norepinephrine, serotonin Mediator molecules include aldosterone, melatonin, insulin, calcitonin
Which of the following are not considered current treatments for Parkinson's Disease? Dopamine Agonists Stem Cell Treatment Monoamine Oxidase-B (MAOB) Inhibitors Levodopa (L-DOPA) O Catechol-O-methyltransferase (COMT)
Which of the following Parkinson's Disease symptoms is thought to be related to the serotonergic system? Sleep disturbances Rigidity Akinesia Constipation Erectile Dysfunction
