- adj. Of or pertaining to the coelom
Sorry, no etymologies found.
The cortical portion is first recognizable about the beginning of the fourth week as a series of buds from the celomic cells at the root of the mesentery.
Later it becomes completely separated from the celomic epithelium and forms a suprarenal ridge projecting into the celom between the mesonephros and the root of the mesentery.
Each suprarenal gland consists of a cortical portion derived from the celomic epithelium and a medullary portion originally composed of sympatho-chromaffin tissue.
The ovary, thus formed from the genital ridge, is at first a mass of cells derived from the celomic epithelium; later the mass is differentiated into a central part or medulla (Fig. 1112) covered by a surface layer, the germinal epithelium.
The original evaginations form a series of transverse tubules each of which communicates by means of a funnel-shaped ciliated opening with the celomic cavity, and in the course of each duct a glomerulus also is developed.
By the fifth or sixth week this body forms an elongated spindle-shaped structure, termed the urogenital fold (Fig. 1106), which projects into the celomic cavity at the side of the dorsal mesentery, reaching from the septum transversum in front to the fifth lumbar segment behind; in this fold the reproductive glands are developed.
According to the review of this article, Toldt explains the case by assuming that other parts of the celomic epithelium, besides that of the mesogastrium, are capable of forming splenic tissue.
