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.

Urinary Bladder of Animals The urinary bladder is a musculo-membranous sac, differs in form, size and position according to the amount of its contents. Urinary bladder of Ox When contracted, it is a dense pyriform mass about the size of a fist and lies on the ventral wall of the pelvic cavity at a variable distance

Ureter of Animals Ureter of Ox The ureters of Ox are the excretory ducts of the kidneys and each begins at the junction of the calyces majors and terminates at the bladder. It is about 6 to 8 mm in diameter. The right ureter emerges out of the hilus of the right kidney from its

Kidney of Animals The urinary organs are the kidneys, ureters, bladder and urethra. The kidneys are glands that secrete the urine. The ureters are tubes, which convey the urine to the urinary bladder and the urinary bladder is a reservoir for the urine. The urine accumulates in the bladder and is then expelled through the urethra.
