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.
afferent arteriole. enters the glomerulus at the vascular pole and divides into capillaries which subsequently merge to form efferent arterioles. efferent arteriole. derived from the glomerular capillaries in the renal glomeruli, these arterioles exit from the glomerulus at its vascular pole.nters the glomerulus at the vascular pole and divides into capillaries which subsequently merge to form efferent arterioles. efferent arteriole. derived from the glomerular capillaries in the renal glomeruli, these arterioles exit from the glomerulus at its vascular pole.
