    ill only put up 3 this time....last one was a little bit too lengthy

    1) At the venule end of a capillary bed the hydrostatic pressure is...
    a) larger than the osmotic pressure
    b) smaller than the osmotic pressure
    c) the same as the osmotic pressure
    d) both a and b
    e) none of the above

    2) After a child birth what happens in order for the foramen ovale to close?
    a) increased pressure in the right atrium compared to decreased pressure in the left ventricle
    b) increased pressure in the left atrium compared to decreased pressure in the right atrium
    c) decreased pressure in the right atrium compared to increased pressure in the left atrium
    d) increased pressure in the right ventricle compared to increased pressure in the left ventricle
    e) none of the above

    3) Which innervates the viscera?
    a) phrenic nerve
    b) vagus nerve
    c) hypopheceal nerve
    d) visceral nerve
    e) sympathetic nervous system

    Hey, I just found that out too, before reading Droha's answer. Yeah, B and C look the same. Anyway, these are good questions. Can I know where you get them from?
    BTW, I'm waiting for test number 6 and 7

    The sympathetic nervous system also innervates the viscera, just not exclusively. I would not include that as an answer choice if you are looking for VAGUS to be correct.

    In fact, the vagus nerve innervates a few skeletal muscles as well. So both of these answers could be correct.

    Isnt it the parasympathetic that uses the vagus nerve to stimulate the viscera exclusively...

    In any case the vagus nerve is the one that innervates the viscera...the parasympathetic or the sympathetic nervous system as you put it just uses the vagus nerve to innervate the viscera but vagus nerve stimulates the viscera...

    Viscera = organs and they have both parasymp and symp innervation (think about fight or flight - how are you going to shut down systems like GI and renal without symp stimulation to the gut and kidneys?). The viscera are almost 100% innervated by the vagus parasympathetically but T1-L2 are responsible for the sympathetic innervation to the viscera.

    The vagus nerve is parasympathetic, not sympathetic (it is a cranial nerve). In addition to the various organs it innervates, it is also responsible for the innervation of a select few skeletal muscles.
