external pudendal artery

Question 3

what arteries make up the bovine uterine blood supply?

Answer 3

from ovarian, vaginal, and umbilical aa

Question 4

what arteries supply the equine uterus?

Answer 4

from ovarian, vaginal, and external illiac (uterine aa)

Question 5

what arteries supply the equine penis?

Answer 5

obturator, internal + external pudendal aa

Question 6

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?

Answer 6

the umbilical a supplies the apex of the pee bag

Question 7

what stx does the vaginal artery supply?

Answer 7

supplies the rectum, caudal bladder, ureter, uterus and vagina

Question 8

what stx’s does the prostatic a feed after it branches off from the internal illiac in males?

Answer 8

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

Question 9

what are the branches of the internal illiac a. cranial to caudal?

Answer 9

prostatic/ vaginal

venteral peritineal

caudal rectal

artery of the penis

Question 10

what does the caudal gluteal supply?

Answer 10

the caudal gluteal a follows the sciatic n out of the pelvic cavity and terminates in the hamstrings

Question 11

what are the branches off of the caudal gluteal a and what so they supply?

Answer 11

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

Question 12

what artery supplies the tail and terminates the aort

Answer 12

the median sacral a. supplies the tail and terminates the aort

Question 13

what is the branch off the external illiac a.before entering the vascular lacuna and becoming the femoral a.?

Answer 13

deep femoral a.

Question 14

what are the brnches off of the deep femoral a. and what do the supply?

Answer 14

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.

Question 15

what are the lymph nodes of the pelvic cavity abd which one drains the prostate?

Answer 15

• sacral + hypogastric LN’s = sublumbar LN

median illiac LN

together they drain the pelvic cavity

• sacral LN drains the prostate

Question 16

what is found passing threw the inguinal canal’s rings of male and females and what are there boarders?

Answer 16

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-

Question 17

what stxs make up the spermatic cord?

Answer 17

ductus deference

testicular a and v (panpiniform plexus)

Question 18

what are the layers of the scrotum from external to internal?

Answer 18

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

Question 19

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?

Answer 19

horses

careful apoximation of the perineal septum and perineal body.

Question 20

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?

Answer 20

udder

Question 21

what is a preputial diverticulum?

Answer 21

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.

Question 22

what is the difference between an open and closed casteration?

Answer 22

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.

Question 23

the _________ is the ride of the prostatic urethera and the tip that marks the start of the pelvic urethera is called __________?

Answer 23

uretheral crest and the tip is the clalicula seminalus

Question 24

what is the uretheral groove?

Answer 24

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

Question 25

what is criptorcidism?

Answer 25

a heretitary condition where one or both of the testicals do not decend into the scrotum. = retained testicals are more prone to cancer.

• more commonly the R testical will not decend. following the vas deference can take you to the testical is not visible in the abd.
