dog- convex and thin
cow- concave and thin
horse- concave and thin
Describe the thickening of the ishial tuber in the dog, cow, and horse.

cow- triangular thickening
horse- linear thickening
How does the floor of the pelvis of a mare differ from a stallion?
Mare has dorsal concavity, stallion has a slight ridge/
How does the vertical diameter of the pelvis of a mare differ from a stallion?
Mare: Opp S3-4
Stallion: S2
How does the pelvic inlet of a mare differ from a stallion?
Mare: wide and round
Stallion: small and cramped
What are the boundaries of the pelvic inlet?
base of the sacrum dorsally
right and left arcuate lines laterally
pecten pubic ventrally
What is the truncated cone?
Pelvic inlet and outlet
What are the boundaries of the pelvic outlet?
ischial arch
R and L ischatic tuberosities
Caudal edge of R and L sacrosciatic ligaments
What is the length of the pelvic outlet in terms of vertebrae?
3rd to 5th caudal vertebrae
Which is larger? The pelvic inlet or outlet?
pelvic inlet
What are the peritoneal pouches ?
Reflections of peritoneum in the pelvic cavity
Which pouch is located on either side of the rectum?
pararectal fosaa
Which pouch is located between the rectum and the genital tract?
Rectogenital pouch
Which pouch is located between the urinary bladder and the genital tract?
vesicogenital pouch
Which pouch is located between the pubis and the urinary bladder?
pubovesical pouch
What is the perineum?
The body wall that closes the pelvic cavity caudally (pelvic outlet)
What does the perineum surround?
anal and urogenital canals
The perineum has two boundaries: superficial and deep. True or false?
True
Where are the superficial boundaries of the perineum located?
on the surface of the animal
What are the dorsal, lateral, and ventral boundaries of the superficial perineum?
dorsal: base of the tail (coccygeus and levator m.)
lateral: semimembranous m.
ventral: scrotum or udder
What are the dorsal, lateral, and ventral boundaries of the deep perineum?
dorsal: sacrum and first few caudal vertebrae
lateral: sacrosciatic ligament
ventral: floor of the bony pelvis
What is the perineal body?
deep portion of perineum; muscular and fascial layers forming a midline mass between anal and urogential canals
Where is the perineal body located in males and females?
males: between anus and origin of the body of the penis
females: between anus and dorsal commissure of vulva
What is the common cavity?
Created during foaling as a result of the laceration of the perineal body
How are perineal lacerations elevaluated?
3 grades
Why would a common cavity require surgical repair?
Due to fecal contamination of the genital tract
What is the perineal region?
the superficial projection of perineum on the skin; it is ONLY SKIN DEEP
Describe the location of the perineal region?
Extends from root of tail between the semimembranosus muscles, ventrally to the base of the udder or scrotum
