AB The  student  understands  the  general  mechanisms  involved  in  local  vascular  control:Identifies  the  major  ways  in  which  smooth  muscle  differs  anatomically  and  functionally  from  striated  muscle.Lists  the  steps  leading  to  cross-bridge  cycling  in  smooth  muscle.Lists  the  major  ion  channels  involved  in  the  regulation  of  membrane  potential  in  smooth  muscle.Describes  the  processes  of  electromechanical  and  pharmacomechanical  coupling  in  smooth  muscle.Defines  basal  tone.Lists  several  substances  potentially  involved  in  local  metabolic  control.States  the  local  metabolic  vasodilator  hypothesis.Describes  how  vascular  tone  may  be  influenced  by  endothelin,  prostaglandins,  histamine,  and  bradykinin.Describes  the  myogenic  response  of  blood  vessels.Defines  active  and  reactive  hyperemia  and  indicates  a  possible  mechanism  for  each.Defines  autoregulation  of  blood  flow  and  briefly  describes  the  metabolic,  myogenic,  and  tissue  pressure  theories  of  autoregulation.Defines  neurogenic  tone  of  vascular  muscle  and  describes  how  sympathetic  neural  influences  can  alter  it.Describes  how  vascular  tone  is  influenced  by  circulating  catecholamines,  vasopressin,  and  angiotensin  II.Lists  the  major  influences  on  venous  diameters.Describes  how  control  of  flow  differs  between  organs  with  strong  local  metabolic  control  of  arteriolar  tone  and  organs  with  strong  neurogenic  control  of  arteriolar  tone.
