Urogenital system (male and female) Flashcards
Describe pararectal fossa, rectogenital pouch, vesicogenital pouch, rectovesical pouch, and pubovesical pouch.
These pouches each describe the location of the bladder, rectum, and genitalia relative to one another.
Pararectal: area between rectum and dorsal body wall
Rectogenital: area btw rectum and genitalia
Vesicogenital: area btw bladder and genitalia
Rectovesical: area btw rectum and bladder
Pubovesical: area btw bladder and ventral body wall
Describe the difference between a closed and open castration.
A closed castration involves leaving the parietal vaginal tunic on the testicals, an open castration involves opening the parietal tunic (thus exposing the animal to possible infection risk).
What structures are located in the male inguinal canal?
Spermatic cord Cremaster muscle Genitofemoral nerve External pudendal artery and vein Vaginal tunic
What type of placenta does the ruminant have?
Cotyledonary
True or false: Equine placenta is zonary.
False, it is diffuse, dogs and cats possess zonary placenta.
Where does the genitofemoral nerve supply its sensory innervation?
To the genitalia
Where does the vestibule end?
At the external urethral orifice
How many mammary glands does the mare have? The cow?
2 and 4 respectively
True or false: The external pudendal artery provides important blood supply to the equine mammae.
True, along with its cranial and caudal mammary arteries
What is the main vein associated with the bovine mammary glands?
Cranial superficial epigastric vein or “milk vein”
What important arteries supply the bovine mammae?
From the external pudendal artery, the cranial and caudal mammary arteries and the cranial superficial epigastric
These are also called the suspensory apparatus of the udder.
Lateral and medial laminae and suspensory laminae (inside)
True or false: The sigmoid flexure and the urethral diverticulum are found in the bull and boar
False, they are both ONLY found in the bull
These are also called seminal vesicles in the horse only.
Vesicular glands (though we would also find these glands in the bull and boar)
Why is the ovulation fossa in the mare unique?
Because where most species have blood and lymph on the inside and their ovulation fossa on the outside, the mare has blood/lymph on the outside and an ovulation fossa on the inside.
