para-aortic bodies(redirected from aortic glomera)
small masses of chromaffin cells near the sympathetic ganglia along the abdominal aorta that secrete norepinephrine. They reach their maximum size during fetal life and then degenerate during childhood as the adrenal medulla matures. Tumors of these structures produce symptoms similar to those of pheochromocytoma. Called also organs of Zuckerkandl.
small masses of chromaffin tissue found near the sympathetic ganglia along the aorta; they are more prominent during fetal life. The chromaffin cells secrete noradrenalin; chemoreceptive endings monitor levels of blood gases.
