The mesorchmm extends to the bottom of the tunica vaginalis, forming a narrow fold (ca. 1 cm. wide) which attaches the epididymis to the posterior part of the tunic. Vesicula seminalis Body of prostate. External urethral orifice Fig. 522.âGeneral View of Genital Organs of Etjli- The inguinal canal presents several special features in the bull. The abdominal ring is very- long. Its anterior border, formed by the edge of the internal oblique, is decidedly concave and is tendinous in its medial part. The long axis of the subcutaneous ring is directed outward, for- ward, and downward. The spermatic cord lies in its lateral part, the external pudic vessels in its middle. A muscular band about an inch wide, detached from the internal oblique muscle, crosses the lateral side of the vaginal ring. The ductus deferens is small in caliber and has a much thinner wall than that of the horse. At first it pursues a fiexuous course upward along the posterior border of the testicle, then becomes straight and has in the posterior part of the spermatic cord. The genital
