The abdominal part of the internal spermatic artery is similar in structure to a distributing artery of the same size. At the end of this abdominal part and the beginning of the funicular part, the lamina elastica interna is spilt into two membranes enclosing between them fibro-elastic tissue, and longitudinal smooth muscle cells respectively, Along the course of the funicular part, the artery possesses intimal cushions of variable size and form. Some of the proper testicular arteries are of the thin-walled type. Other vessels posses elastic muscular intimal polsters and still others show an inner longitudinal and outer circular mediae. Typical and atypical glomus vessels are well demonstrated in the stroma of the testis. The arteries of the body and tail of epididymis show an intimal thickening formed of longitudinally arranged smooth muscle cells.
