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.
Efferent arterioles of glomeruli in the outer cortex form the peritubular plexus which surrounds proximal and distal tubules. Efferent arterioles of glomeruli in the deeper cortex contribute to the adjacent peritubular plexus and also form the vasa recta which accompany the loop of Henle into the medulla.
