Organ of Zuckerkandl.

There are several extradrenal sites where pheochromocytoma occurs, and this, the 'organ of Zuckerkandl' is one interesting site.

It actually is a cluster of bodies,located either at the bifurcation of the abdominal aorta or at the origin of the inferior mesentric artery and they contain chromaffin cells derived from the neural crest.

These are also known as 'paraortic bodies' but differ from 'corpora aortica'(also a chromaffin body)which lies near to the thoracic aorta.

The organ of Zuckerkandl is said to be responsible for secreting catecholamines and other vasoactive substances. It has a function of supplying catecholamines to the fetus especially in the first trimester of pregnancy and regresses usually in the third trimester.
