pelvic/repro stxs and their blood supply Flashcards
_________ is the sole blood supply for the penis of the bull.
Internal pudendal artery
with cows, the primary blood supply of the udder is by the ______ artery with a small supply from the internal pudendal artery via the dorsal labia artery
external pudendal artery
what arteries make up the bovine uterine blood supply?
from ovarian, vaginal, and umbilical aa
what arteries supply the equine uterus?
from ovarian, vaginal, and external illiac (uterine aa)
what arteries supply the equine penis?
obturator, internal + external pudendal aa
the internal illiac a gives rise to the umbilical a before becomming the internal pudendal and caudal gluteal aa. What does the umbilical a supply?
the umbilical a supplies the apex of the pee bag
what stx does the vaginal artery supply?
supplies the rectum, caudal bladder, ureter, uterus and vagina
what stx’s does the prostatic a feed after it branches off from the internal illiac in males?
ductus deference via the artery of the ductus
urethera via the uretheral a.
ureter via the uteretal a.
caudal urinary bladder via the caudal vesical
rectum and anus via the middle rectal a
and the prostate
what are the branches of the internal illiac a. cranial to caudal?
prostatic/ vaginal
venteral peritineal
caudal rectal
artery of the penis
what does the caudal gluteal supply?
the caudal gluteal a follows the sciatic n out of the pelvic cavity and terminates in the hamstrings
what are the branches off of the caudal gluteal a and what so they supply?
the caudal gluteal branches are the
- iliolumbar a : mm of the lumbosacral juxn; gluteals; proximal femral
- crainial gluteal: mm of the lumbosacral jxn; gluteals; proximal femoral
what artery supplies the tail and terminates the aort
the median sacral a. supplies the tail and terminates the aort
what is the branch off the external illiac a.before entering the vascular lacuna and becoming the femoral a.?
deep femoral a.
what are the brnches off of the deep femoral a. and what do the supply?
pudendo epigastric trunk (not always present) which bifercates into the caudal eipigastric a: rectus abdomonis; caudal ventral abd wall and the external pudendal a.: follows the inguinall canal and terminates in the testies; caudal abd wall. the external pudendal then gives off the caudal superficial epigasteric a.: supplies caudal superficial abd wall.
what are the lymph nodes of the pelvic cavity abd which one drains the prostate?
- sacral + hypogastric LN’s = sublumbar LN
median illiac LN
together they drain the pelvic cavity
- sacral LN drains the prostate
what is found passing threw the inguinal canal’s rings of male and females and what are there boarders?
superficial inguinal
- boarders: inguinal lig; aponarosis of the external abd oblique m.
- passes (female): the vaginal process; round lig of the bladder external pudendal a and v. and genitofemoral n. (male): vaginal tunic- external pudendal a and v. and genitofemoral n.; spermatic cord cremaster m.
Deep inguinal ring
boarders: lateral boarder of the rectus abdomonis;caudal boader of the internal abdominal oblique m; inguinal lig.
passes: male-
what stxs make up the spermatic cord?
ductus deference
testicular a and v (panpiniform plexus)
what are the layers of the scrotum from external to internal?
skin
dartos m - puckers scrotum
cremaster m - arisis from the free boarder of the internal abd ablique and inserts on the vaginal tunic near the testis- lifts testical closer to the body
spermatic fascia - from transversalus and abd fascia surrounds stxs emerging from the superfial inguinal ring.
periatal vaginal tunic - diverticulum of peritinium
vaginal cavity
visceral vaginal tunic - diverticulum of peritinium
tunica albuginia
testis
perineal lacerations that occur during both is a common injury in which species?
For repair of a tear from anus to through the vestibule/vigina what is most important?
horses
careful apoximation of the perineal septum and perineal body.
a paired medial lamina seperates the ______ of ruminate mammles and can be removed in pairs of the left or right in the case of injury or sever mastitis?
udder
what is a preputial diverticulum?
a part of the prepuse specific to the boar. it can be removed for potbelly big pets (remove oder); removed in breading boars to prevent the penis from becoming trapped or cought in it.
what is the difference between an open and closed casteration?
open- the vaginal cavity thus the abd cavity is opoened to expose the testicular vessles for “better” ligation.
Closed - the vaginal cavity is not opened and ligations are placed over the layers of the spermatic cord and vessles.
the _________ is the ride of the prostatic urethera and the tip that marks the start of the pelvic urethera is called __________?
uretheral crest and the tip is the clalicula seminalus
what is the uretheral groove?
a groove on the venteral side of the penis that the urethera passes trough. common place for uroliths to get logged.
Note: the ospenis passes through the glands penis of the dog
