Exam I - Large Animal Urogenital Nonsense Flashcards
Name the three main regions of the bull dick.
the root, the body, & the glans penis
What ‘type’ of penis does a bull have?
fibroelastic
Elongation of the penis in the bull is acheived by:
straightening the sigmoid flexure
Which artery supplies the ureters, bladder, & ductus deferens in the bull?
umbilical a.
(off of the internal iliac a.)
Which artery supplies the prostate gland in the bull?
prostatic a.
The stallion has what ‘type’ of penis?
musculocavernous
Describe the shape of the sigmoid flexure in the penis of the stallion.
The premise is false. The stallion shlong doesn’t have a sigmoid flexure
In the equine, which region are the ovaries located?
lumbar region
In the bovine, which region are the ovaries located?
pelvic region
Name the structure located between the uterine horns of the Heifer that connects the horns together.
Intercornual ligament
Which artery supplies both the ovaries and the uterus in the bovine?
ovarian a.
Which artery supplis the uterus & the bladder in the bovine?
umbilical a.
Which artery supplies the uterine body in the bovine?
uterine a.
Which artery supplies the vagina & distal uterus in the bovine?
vaginal a.
The ________ of the female is the body wall that surrounds the anus & vulva and covers the pelvic outlet
perineum
The ________ is the area between the anus & external genitalia, and can be torn during foaling
perineal body
(or the gooch… via urban dictionary)
Which artery supplies the ovaries & the cranial part of the uterus in the mare?
ovarian a.
The uterine a. is a branch of which artery in the mare?
external iliac a.
Which artery supplies the rectum, anus, & perineum, as well as vagina, bladder, and ureters in the mare?
**internal pudendal a. **
Which artery in the mare supplies the vagina, bladder, ureters, & distal uterus?
vaginal a.
In the cow, the caudal superficial epigastric v. and the cranial superficial epigastric v. anastamose to form the:
milk vein.
Lymphatic vessels of the mammary glands generally travel in a __________ direction
dorso-caudal
Which nerves provide sensory innervation to the mammary glands in the bovine?
- iliohypogastric n.
- ilioinguinal n.
- genitofemoral n.
- pudendal n.
If I were in a pasture and I pointed to something and said “damn, that animal has a long vagina,” which animal am I likely pointing to?
A cow. Cows have long vaginas
The **suburethral diverticulum **is present in which species?
cows & sows
Are the ovaries located more cranially in the mare or the bovine?
mare
If I were in a pasture and I pointed to an animal and said “damn, that animal has a short neck of the bladder,” which animal am I likely pointing to?
A cow.
Which species have a cotyledonary placenta?
large and small ruminants
Which species have a diffuse placenta?
equine
Which species have a zonary placenta?
dogs and cats
In which species does the cervix protrude into the vagina?
equine & bovine
(not swine)
Heifer or Mare?
Heifer
Ovaries are more cranial in a mare
In the cow, which artery is palpable rectally and is used in pregnancy diagnosis?
uterine a.
The uterine artery can be distinguished from the internal iliac artery because the uterine artery is mobile. The internal iliac a. is in a relatively fixed position
The distal part of the uterus in the cow is supplied by branches from which artery?
vaginal a.
Is the uterine artery in the mare a branch of the internal iliac a. or the external iliac a.?
In the mare, the uterine a. is a branch of the external iliac a.
This is a significant species difference because in the bovine, the uterine a. is a branch of the internal iliac a.
Think _E_**quine = _E_xternal
Species?
Sow
The lateral laminae in the udders originates from the ____________
The lateral laminae in the udders originates from the symphyseal tendon
Arterial blood supply to the mammary gland is provided by:
external pudendal a.
(and a smaller contribution from **internal pudendal a. **via the ventral perineal a.)
The mammary lymph nodes are also known as:
superficial inguinal lymph node
Name the lymphatic vessel in the cow that lies between the deep circumflex & external iliac arteries
deep inguinal (iliofemoral) lymph node
Describe the blood supply to the mammary glands of the mare.
- caudal epigastric a. from external pudendal a.
- ventral labial a. from internal pudendal a.

This is a bull (but not a whole bull… only a bit of a bull)
ampulla of ductus deferens
Identify the structure indicated by the red arrow.
This is a bull
vesicular gland
