Veterinary Anatomy

Uterus Masculinus or Utriculus Prostaticus of Male Animals The uterus masculinus is a rudimentary structure and a remnant of the paramesonephric (Müllerian) duct in males. It is located between the ampullae and the seminal vesicles, positioned on the caudal-dorsal surface of the urinary bladder, and cranial to the prostate gland. This structure is present in approximately 50–70% of bulls. Species Variations of the Uterus Masculinus

Vas deferens of Animals Vas deferens of Bull The ductus deferens or vas deferens of bull extends from the tail of the epididymis to the pelvic part of the urethra. It is at first, pursues a very tortuous course upwards along the caudal border of the testicle. It then becomes straight and runs in the

Decent of testes in Animals During early fetal life, the testicles are situated against the dorsal wall of the abdomen in contact with the visceral surface of the kidneys, these testes descend in animals scrotum to fully function. They are attached to the sub – lumbar region by a fold of peritoneum – the mesorchium

Tunica Vaginalis of Animals Tunica vaginalis of Animals is an evagination of parietal peritoneum passing through the inguinal canal into the scrotum. When fully developed, it has the shape of a flask with narrow proximal part and a distended distal part The proximal part contains the spermatic cord and the distal part has the testis and epididymis. Like the

Spermatic Cord of Animals Spermatic Cord of Ox The spermatic cord of Ox consists of structures carried down by the testicle in its migration through the inguinal canal from the abdominal cavity into the scrotum. It begins at the abdominal inguinal ring where all the constituent structures come together, passes through the inguinal canal and

Testes and Epididymis of Animals The testicles are two elongated oval, compound tubular glands situated in the scrotum and suspended by the spermatic cords. Testes and Epididymis of Bull The long axis of the testis is vertical to the long axis of the body and each is slightly compressed from side to side and presents

The anatomy of the scrotum in animals is specialized to protect the testes and regulate their temperature for effective sperm production.
