Themediastinum testis giving off numerous fibrous cords in a radiated directionto the internal surface of the tunica albuginea. The cut extremities of thevessels below the nunciber belong to the rete testis; and those above, to thearteries and veins of the organ. 4. The tunica vasculosa, or pia mater One of the lobules, consisting of the convolutions of the tubuli seminiferi,and terminating by a single duct, the vas rectum. Corresponding lobulesare seen between the other fibrous cords of the mediastinum. 6. Section ofthe 616 STRUCTURE OF THE TESTIS. imous with the vas deferens. The testis is invested by three tunics,tunica vaginalis, tunica albuginea, and tunica vasculosa, and is con-nected to the inner surface of the dartos by a large quantity ofextremely loose areolar tissue, in which fat is never deposited, butwhich is very susceptible of serous infiltration. The Tunica vaginalis is a pouch of serous membrane derived fron;the peritoneum in the descent of the testis, and afterwards obliteratedfrom the abdomen to within a short distance of the gland. Like otherserous coverings, it is a shut sac, investing the organ, and thencereflected so as to form a bag around its circumference: hence it isdivided into, the tunica vaginalis propria and tunica vaginalis tunica vaginalis propria covers the surface of the tunica albuginea,and surrounds the epididymis, connecting it to the testis by means ofa distinct duplicature.
