Intro into Female and Male Reproductive tracts

Question 1

ovary in dog is fixed by what

Answer 1

suspensory and proper ligaments

Question 2

suspensory ligament of ovary

Answer 2

found in carnivores, a peritoneal fold,
thickened along its free margin, that
attaches to the transverse fascia close
to the last rib in the dog, in the cat
reaches the diaphragm and allows the
ovary greater mobility

Question 3

proper ligament of the ovary

Answer 3

extends from the caudal pole of the
ovary to the adjacent tip of the horn
of the uterus

Question 4

Fornix

Answer 4

a blind ended intrusion of
the cervix into the cranial part of the
vagina reduces the lumen of this part
to a potentially ringlike space known
as the fornix. It is only a ventral space
in the dog.

Question 5

urethral orifice

Answer 5

located directly caudal of the vestibulo-vaginal junction

Question 6

vestibule

Answer 6

from urethral orifice to external vulva

Question 7

vestibular glands

Answer 7

more caudal within the vestibule, secretes lubrication nescessary for coitus and partuition

Question 8

Gartners ducts

Answer 8

remnants of the mesonephric ducts that might be found in the broad ligament parallel with
the lateral uterine tube and lateral walls of vagina and cervix (more often seen in cattle)

Question 9

vestibular bulb

Answer 9

patch of erectile tissue found within the vestibule walls

Question 10

broad ligament originates from..

Answer 10

abdominal roof and pelvic walls

Question 11

what does the cranial part of the broad ligament hang and suspend

Answer 11

hang vertically, suspend the ovary, uterine tube and horn of the uterus

Question 12

what does the caudal part of the broad ligament hang and suspend

Answer 12

passes more horizontally, attaches to the side of the body of the uterus, cervix and cranial part of the vagina

Question 13

broad ligament can be subdivided into what

Answer 13

mesometrium, mesovarium, mesosalpinx

Question 14

mesometrium

Answer 14

portion of the broad ligament that attaches to the uterus

Question 15

mesovarium

Answer 15

distal from its attachment inot the abdominal roof, mesovarium supports ovary

Question 16

mesosalpinx

Answer 16

mesovarium releases lateral fold that passes onto the uterine tube

Question 17

round ligament of the uterus

Answer 17

a cord of fibrous tissue and smooth muscle, passes from the tip of the horn of the
uterus toward (and in the bitch, through) the inguinal canal, it is supported by a special fold detached from the
lateral surface of the broad ligament

Question 18

ovarian bursa

Answer 18

fusion of the mesovarium and mesosalpinx that entrap the ovary

Question 19

describe the path of blood supply to the uterus from the aorta

Answer 19

aorta branches into ovarian artery then uterine artery

Question 20

describe the path of blood supply from the aorta all the way to the urethra in female carnivores

Answer 20

from aorta –> internal illiac –> internal pudendal which branches into both the vaginal and urethral arteries. The vaginal artery then branches into uterine atery.

Question 21

male urethra boundaries (pelvic vs penile parts)

Answer 21

pelvic part: very short first part leaded from the bladder and completely surrounded by prostate gland

penile part: thin sleeve of spongy tissue within the striated urethralis muscle

Question 22

ductus deferens

Answer 22

tubular structure, carries spermatozoa from the epididymis to the urethra, gains access to the lumen of the urethra via the openings to the deferent ducts within the seminal colliculus

Question 23

genital fold

Answer 23

located on the dorsal surface of the bladder between the two deferent ducts, ventral
to this fold is the vesicogenital pouch of the peritoneal cavity

Question 24

ampullary gland

Answer 24

enlargement of the distal end of the deferent duct lying on the bladder, enlargement is due to glandular tissue in the mucosa and not a widening of the lumen; small and hard to see in doggies

Question 25

prostate gland

Answer 25

present in all domestic species, in some it consists of two parts; one is diffusely
spread within the pelvic wall of the urethra, and the other is a compact body placed external to the
urethralis, both parts drain by very small prostatic ducts which are found just rostral to the
ejaculatory duct on the seminal colliculus

Question 26

seminal colliculus

Answer 26

thickening on the dorsal surface of the bladder, contains openings of the
deferent duct and prostatic ducts

Question 27

path of blood supply in male carnivores from the aorta to the urethra (and everything in between)

Answer 27

aorta –> testicular and internal illiac. Internal illiac –> internal pudendal –> prostatic and urethral. Prostatic into artery of ductus deferens
