The external seam that divides the scrotum is called the:

The external seam is the median raphe. It forms where the labioscrotal folds fuse along the midline during embryonic development, so a visible seam runs down the scrotum and continues onto the underside of the penis as the penile raphe. This is different from the scrotal septum, which is an internal partition that divides the scrotum into left and right compartments; the tunica vaginalis, a serous membrane, covers the testis; and the cremasteric muscle is a muscle layer that helps elevate the testis.
