Layers of subcutaneous fat in ant abdominal wall?
Campers and scarpas fascia
2 muscles of rectus sheath
rectus abdominis and pyramidalis
3 muscles lateral to rectus sheath
external oblique, transversus abdominis and internal oblique
Vessels and innervation of rectus sheath
6 lower thoracic nerves and superior and inferior epigastric vessels
What happens to aponeurosis and inferior epigastric at arcuate line
Aponeurosis passed over the rectus sheath at ASIS and inferior epigastric enters to join with superior
3 main blood vessels supplying abdomen
Superficial = femoral artery (sup epigastric and superior circumflex) internal thoracic (superior epigastric and musculophrenic) and external iliac (inferior epigastric and deep circumflex)
5 bones of pelvis
Ishium, ileum, pubic, sacrum, coccyx
2 main ligaments off the sacrum

Muscle group that make up the pelvic floor?
Levator ani muscles
2 main groups of levator ani
Pubococcygeous (puborectalis and pubovaginalis) iliococcygeous
3 structures passing through the pelvic floor
Urethra, vagina and rectum
2 muscles of posterior pelvic floor
Coccygeus and piriformis
where does piriformis insert into and what is its function
inserts into the greater trochanter and abducts and laterally rotates at the hip
blood supply to ovaries
ovarian artery
main 2 ligaments associated with ovaries
suspensory ligament and ovarian ligament
4 parts of the fallopian tube

Nerve roots associated with genitofemoral? where does it divide?
L1-2, at branch of external iliac divides into deep circumflex and inferior epigastric
Where do the anterior rami of s2-s4 leave the pelvis through?
Greater sciatic foreman
Where is the greater sciatic foreman found between?
Piriformis and coccygeus
Nerve root that supplies skin and muscle of perineum
S2-S4
What does aortic plexus become in the pelvis
superior hypogastric plexus
superior hypogastric plexus divides into what
right and left inferior hypogastric nerves
What nerves supply the rectum, bladder and uterus
Left and right inferior hypogastric nerves
how many zones of ureter?
3
Where does ureter enter the bladder?

3 components of clitoris?
clitoris hood, glans clitoris, frenulum
3 ducts found on external genetalia?
Bartholins ducts, Skenes duct and Paraurethral duct
Muscle that borders external genetalia laterally?
Ischiocavernous
Muscle that borders external genetalia medially?
Bulbocavernous
What area of the external genetalia is often damaged in childbirth?
Perineum
Arterial and venous supply to the external genetalia?
Pudendal artery and vein
