Module 7 Syllabi Questions Flashcards
What does the word “pelvis” mean?
basin
What is the “true” pelvis?
pubic symphysis up to pelvic brim - contains pelvic structures
The true pelvis is that part of the pelvic cavity which is situated below and behind the pelvic brim. It is the location of the pelvic viscera (bladder, uterus, ovaries).
What is the “false” pelvis?
expanded portion of pelvic cavity situated above and in front of the pelvic brim.
What are some of the key differences between a male and female bony pelvis?
female has wider subpubic angle also a wider pubic arch
female superior aperture of the true pelvis is larger and more oval, inferior aperture is also larger and the coccyx is more movable (helps during birth)
What are the lesser and greater sciatic foramina?
separated by the sacrospinous ligament (connects ischial spine - sacrum) crossing sacrotuberosity ligament
What are the boundaries of the ischioanal (ischiorectal) fossa?
Levator ani (top)
Obturator internus (side)
Anus/vagina (side)
UGD (bottom)
What important structures run in the lateral wall of the ischioanal/ischiorectal fossa?
internal pudendal nerve (S2, 3, 4), artery, vein, inferior rectal n, levator ani, coccygeus muscle
What is meant by the terms “urogenital triangle”, “anal triangle” “urogenital diaphragm” and “pelvic diaphragm”? What is a “diaphragm”?
urogenital triangle: pubic symphysis, ischial tuberoscities
anal triangle: coccyx, ischial tuberoscities
UGD: deep perineal pouch; forms shelf superficial to pelvic diaphragm; has 2 fascia layers w/ muscle; has bulbourethral glands, deep transverse perineal muscle, external urethral sphincter, vaginal sphincter
pelvic diaphragm: muscles that form pelvic floor so levator ani and ischiococcygeus
diaphragm: separator
differences between the UGD in males and in females?
males: bulbourethral gland present
females: vaginal sphincter
What is an erectile “body”?
tissue that causes erection
How many erectile bodies in penis?
3
How many erectile bodies in clitoris?
2
Major anatomical difference btwn penis and clitoris?
clitoris is only corpus cavernosum; penis is both cavernosum and spongiosum
uterus muscle type?
smooth
urinary bladder muscle type?
smooth
what runs through greater sciatic foramen
sciatic nerve (L4-S3)
what runs through lesser sciatic foramen
pudendal n., n. to obturator internus, tendon of obturator internus
From what nerves do the pelvic viscera receive their sympathetic innervation? Parasympathetic innervation?
Sympathetic:
Lesser and Lumbar splanchnics
Parasympathetic:
Pelvic Splanchnics
why back alley abortion dangerous?
instrument inserted through vagina can pierce posterior fornix, penetrate peritoneal cavity
How many parts of the urethra are there in the male? In the female?
4 in male; 1 in female
What is the anatomical basis for women being particularly susceptible to Urinary Tract Infections (UTIs)?
short urethra
What is the anatomical basis for an ectopic pregnancy?
ovum gets fertilized in the peritoneum, pregnancy develops there instead of within uterus
If the ovarian artery is blocked, could the ovary still have a blood supply? If yes, how? If not, why not?
yes b/c anastomoses with:
uterine, vaginal, and internal pudendal arteries
What and where are the ischiocavernosus and bulbospongiosus muscles in the male and in the female
they are the skeletal muscles of the superficial pouch
