A chronic and relapsing brain disease that presents with compulsive drug seeking and use. correct answer: Addiction This disorder has symptoms divided into four groups: impaired control, social impairment, risky use, and pharmacological criteria, such as tolerance and withdrawal. correct answer: Substance Use Disorder Poor function or incompetence. correct answer: Impairment Using prescription drugs without a designated script, using prescribed dosage in excess, or using a prescribed...

A postsynaptic potential is excitatory (EPSP) if the ion involved has a reversal potential (Eion) that is more depolarized than the resting membrane potential (Vm or Vrest), even if that Eion is hyperpolarized to the threshold for firing an action potential. - False why?>> For a postsynaptic potential to be excitatory, the reversal potential for the ion involved must be depolarized to the threshold for firing an action potential. An EPSP increases the likelihood of firing. If Eion is...

Action potential of Cardiac Muscle - Early fast Na+ channels open depolarizes. Na+ channel inactivate cause slight dip. Slowly developing long lasting Ca2+ channels open plateaus. K+ channels open repolarizes. Contraction of Cardiac Fibers - Action potential enters. Voltage gated Ca2+ channels open. Ca2+ enters through DHP receptor proteins. Calcium mediated calcium release: Ryanodine receptors open when interact with Ca2+, allowing Ca2+ to enter cytoplasm Calcium bind to troponin to ini...

Steps for an Action Potential - Depolarizing stimulus, if threshold is met - Na+ and K+ channels begin to open, Na+ enters the cell and depolarizes it, Na+ channels close and K+ channels open fully, K+ exits the cell until it is hyperpolarized, K+ channels close, cell returns to resting membrane potential Membrane permeability of molecules (most to least) - Lipophilic, small & non-polar, small & polar, large & polar, charged Sodium-potassium pump function - Pump 3 Na out, and 2 K in SGLT (...
