emphysema and fick's equation - airway obstruction as a result of inorganic particles --> triggers the production of elastase which breaks down elastin --> alveoli lose elastance --> alveoli recoil --> increase in T and decrease in A --> lower gas exchange inspired partial pressure - Pi,o2 = Fo2 * (Patm - Ph2o) air conditioning during inhalation: adds warmth and moisture to the gas --> water gets evaporated in the mucosa, generating a water pressure which decreases the at...

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...

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 (...

How does the Morris Water Maze task function? - A mouse is placed in a murky water tank and, because mice do not enjoy being in water, it will try to look for a way out, and after many trials the mouse learns that there is a platform somewhere in the tank upon which it can rest from swimming, and these trials show that the mouse becomes progressively quicker at finding the platform, demonstrating that it maintains memory of where the platform is in the tank; when a trained mouse is given a ...

What does the thalamus do? - 1. relay station (receives info and tells it where to go) 2. receives sensory fibers from optic tract, ears, and spinal cord 3. receives motor info from cerebellum 4. projects fibers to the cerebrum 5. receives messages from all the sensory receptors and relays it to the proper part of the cerebrum What does the cerebellum do? - 1. coordinates movement and balance 2. processes sensory info and receives input from muscles 3. associated with ataxia (uncoordinate...

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...
