What is the organ of Zuckerkandl?

The organ of Zuckerkandl comprises of a small mass of chromaffin cells derived from neural crest located along the aorta, beginning cranial to the superior mesenteric artery or renal arteries and extending to the level of the aortic bifurcation or just beyond.

What is a paraganglioma?

Paraganglioma is a type of neuroendocrine tumor that forms near certain blood vessels and nerves outside of the adrenal glands. The adrenal glands are important for making hormones that control many functions in the body and are located on top of the kidneys.

What stimulates chromaffin cells?

In order to activate chromaffin cells, the splanchnic nerve of the sympathetic nervous system releases acetylcholine, which then binds to nicotinic acetylcholine receptors on the adrenal medulla. This causes the release of catecholamines.

What does paraganglioma feel like?

Some of most common symptoms are pain, hoarseness, fainting (syncope), difficulty swallowing (dysphagia), eye problems (Horner syndrome), and paralysis of the tongue. Cervical paragangliomas are slow-growing tumors that can cause palsy and spread into the skull base.

Can paraganglioma be cured?

Paragangliomas (PGLs) are rare chromaffin cell tumors that can often be cured by resection. Although described for the first time in 1886 1, the diagnosis of PGL remains a challenge, because patients do not present with characteristic signs and symptoms.

Where is chromaffin cells found?

adrenal glands
Chromaffin cells make epinephrine (adrenaline) and norepinephrine (noradrenaline). They are found in the adrenal glands or in groups of nerve cells called ganglia.

Why is adrenaline called emergency hormone?

Adrenaline hormone is known as the Emergency Hormone or Epinephrine because it initiates a rapid reaction that helps the person think rapidly and respond to stress. It raises the rate of metabolism, dilating the blood vessels going into the heart and brain.
