Which alternative best describes the microglial cells? -they are concentrated in areas of damage or stroke -they generate micro tears in neuron axons -they produce CSF -myelin sheath producers

- Which of the following describes the concentration of K+ and Na+ ions in and around a resting neuron?1- K+ and Na+ ion concentrations are both higher outside of the cell.2- K+ ion concentration is higher inside of the cell, Na+ ion concentration is higher outside of the cell.3- K+ ion concentration is higher outside of the cell, Na+ ion concentration is higher inside of the cell.4- K+ and Na+ ion concentrations are similar inside of and outside of the cell. - An action potential:1- is a large change in polarization.2- is an "all-or-nothing" response.3- will travel down the length of the axon4- all of the above - What prevents action potentials from traveling away from synaptic terminals?1- Inactivation of Na+ channels behind the zone of depolarization.2- Inactivation of K+ channels behind the zone of depolarization.3- An increased in graded potential along the length of the axon.4- All of the above - Which brain region is incorrectly paired with one of its functions?1- midbrain -…

The following are methods to control for bias during data collection, except: a. Assuring subjects' anonymity and confidentiality b. Reducing the number of participants c. Providing training for interviewers d. Randomly assigning subjects to experimental/control

ACCORDING TO: New Nerve Cell for the Adult Brain By: Gerd Kempermann and Fred Gage   What is the previous evidence that stem cells did exist in the adult brain? (This should be dated, with a brief explanation of the studies) How do we study neurogenesis in animals?  In humans? Where can we find stem cells in the brain?  What is so important about these brain structures?  (For example: Why do we find excess stem cells in these structures, but not in others?) How can stem cell proliferation be inhibited? How might neurogenesis be related to learning and memory?

a 45 year old man with type 2 diabetes mellitus comes to the physician 2 weeks after the sudden onset of progressive involuntary movement of his right arm and leg. on examination the right upper extremity makes flapping and circular motions . the right lower extremity has a jerk-live movement , even when the patient tries to prevent its motion. A decrease in glutamalergic innervation from the subthalamic nucleus to which of the following structures is most likely in this patient. A) left caudate, B) left globus pallidus, C) left putamen , D) left vental anterior nucleus of the thalamus , E) right caudate, F) right globus palidus, G) right putamen, H) right ventral anterior nucleus of the thalamu

Hello, May I get help on this question very soon please? I do not understand it. Question: When your body mounts a sympathetic response, it causes the smooth muscle in your bronchioles to relax and dilate (get wider). By contrast, a parasympathetic response causes the smooth muscles in your bronchioles to contract and constrict (get narrower). This seems strange because fight-or-flight responses seem like they should upregulate activity and cause more contractions. A benefit of bronchiole dilation during fight or flight responses is that it...(see image)

β – waves of the EEG :-a- are observed during relaxed wakeful stateb- are faster than α – waves but slower than theta wavesc- disappear when the person becomes alertd- are observed during REM sleep

The following clinical presentation is designed to assess your ability to anticipate a serious complication of a relatively common medical condition obstructive sleep apnea. Most people think this condition leads to daytime somnolence and fatigue so basically an inconvenience for the sufferer and for those with whom he/she interacts. in reality sleep apnea whether central or obstructive can be life-threatening.  How does CPAP work to treat OSA?
