The structural classification system groups joints into three types: synovial, cartilaginous, and fibrous joints, while the functional, or degree of movement, classification system groups joints into diarthrosis, synarthrosis, and amphiarthrosis type joints. Synovial Joints
In summary, thapsigargin treatment markedly attenuates juxtamedullary afferent arteriolar vasoconstrictor responses to Ang II or NE. In addition, depletion of intracellular calcium pools with thapsigargin completely abolishes the response of juxtamedullary efferent arterioles to these vasoconstrictor agents.hese studies were conducted to determine the role of calcium release from the thapsigargin-sensitive intracellular calcium pool on the Ang II-and NE-mediated vasoconstriction of juxtamedullary afferent and efferent arterioles.
We know that if Afferent arteriole dilates then both GFR n RPF increase. The filtration fraction increases if Afferent arteriole dilation is the dominant affect. Now, if EFFERENT arteriole dilation is the dominant effect, then GFR is increased but Why should the renal plasma flow be decreased????? I thought it should be increased.
