These are the coni vasculosis The sum total of all the coni vasculosi forms the globus major or head of the epididymis. 330. The vasa efferentia and the tubes of the coni vasculosi are about the size of the seminal tubules, but, unlike them, are lined with a layer of beautiful columnar epithelial cells, with a bundle of cilia (Fig. 140). Outside these is generally a layer, more or less continuous, of small polyhedral cells.

Outside these is generally a layer, more or less continuous, of small polyhedral cells. The substance of the columnar cells is distinctly longitudi- nally fibrillated. The mem- brana propria is thickened by the presence of a cir- cular layer of non-striped muscular fibres. The rest, , the globus minor, or tail of the epididymis, is made up of a continuation of the tubes of the globus major, the tubes diminish- ing gradually in number by fusion, and at the same time thereby becoming larger. The columnar epithelial cells, facing the lumen of the tubes of the globus minor, are possessed of cilia of unusual length. The tubes of the epididymis are separated from one another by a larger amount of connective tissue than those of the testis. The tubes of the organ of Giralde, situated in the beginning of the funiculus spermaticus, are lined with columnar ciliated epithelium. So is also the pedunculated hydatid of Morgagni attached to the globus Fig. 140.—A tubule of the epi- didymis in cross section. The wall of the tubule is made up of a thick layer of concentrically ar- ranged n< n-striped muscular tissue, a layer of columnar epithelial cells with extraordinarily long cilia pro- jecting into the lumen of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Klein, E.
