What arae the two muscles of the pelvic diaphragm?
Levator ani and coccygeus muscles
Where do the levator ani muscles originate and insert?
Originate from ossa coaxe
Inert on external anal sphincter
(keeping anus in)

Originate from ossa coxae
Insert dorsocaudally on caudal vertebrae
What is the area of the perineum?
Triangle containing anus and ischoprectal fossa.
What is the M. sphincter ani?
External anus muscles. Arranges circular wiyh sinus paranalis around
What is the artery supply of the pelvis?
Terminal branches of the aorta
- Hind limb/body wall - paired external iliac arteries
- Pelvic region - paired internal iliac arteries
>Internal pudendal artery - pelvic organs, visceral with branches to organs
> Caudal gluteal arter - wall of pelvic cavity - Midline structures and tail - median sacral artery
What are the veins of the pevis?
