- n. Plural form of paraganglion.
Sorry, no etymologies found.
Other examples of the wide and at the same time diversified NGF effects are illustrated by other sympatho-adrenal derivatives such as paraganglia, small intensely fluorescent cells (SIF) and carotid body cells.
The paraganglia of the sympathetic plexuses differentiate next and last of all the paraganglia of the sympathetic trunk.
After birth the chromaphil organs degenerate but the paraganglia can be recognized with the microscope in sites originally occupied by them.
The paraganglia are small groups of chromaphil cells connected with the ganglia of the sympathetic trunk and the ganglia of the celiac, renal, suprarenal, aortic and hypogastric plexuses.
These glands include the thyroid, the parathyroids and the thymus; the pituitary body and the pineal body; the chromaphil and cortical systems to which belong the suprarenals, the paraganglia and aortic glands, the glomus caroticum and perhaps the glomus coccygeum.
