Adrenal medulla neural crest
WebNeural crest cells (NCCs) are highly migratory progenitor cells that give rise to a vast array of differentiated cell types. One of their key derivatives is the autonomic nervous system (ANS) that is comprised in part from chromaffin cells of the adrenal medulla and organ of Zuckerkandl, the sympathetic chain and additional prevertebral ganglia such as the … WebApr 12, 2024 · The 2 main parts of the adrenals have different embryonic origins. The inside core adrenal medulla is neural crest in origin. Mesenchyme surrounding these cells differentiates to form a fetal cortex. This fetal cortex is later replaced by the adult cortex.

WebThe adrenal medulla is made up of polyhedral cells arranged in cords or clumps. Embryologically, the adrenal medullary cells derive from neural crest cells. Medullary cells are innervated by cholinergic preganglionic nerve fibers that reach the gland via the splanchnic nerves. WebOct 17, 2024 · During the 7th week of development, neural crest cells formed at the apex of the neural folds migrate into the adrenal primordium via a ventral pathway. These cells enter the gland from the medial face and then differentiate into chromaffin cells centrally arranged in cords and masses. ... However, the adrenal medulla is innervated by ...
