This is the gunner that we all wish we could answer pimping questions like. Good job Sam.
Sam answering some fire questions while I be getting my 50-50 pimp questions wrong :(
If only I was that sharp! Bravo to the production team, high quality content.
Had to do a double take at 3:11's "Chronic Obstetric Pulmonary Disease"
“Glad I “reviewed” anatomy, my man is a whole professor on rotation.”
Greater (false) pelvis: distrubutes abdorgan weight, supports uterus at term
- parameters:
-- posterior: lumbar vertebrae
-- biateral: illiac fossa
-- anterior: abdo-wall
Lesser (true) pelvis: contiains uterus/ vagina/ bladder/ fallopian tubes/ ovaries/ distal (rectum/ anus)
- parameters:
-- posterior: sacrum/ coccyx
-- bilateral: ischium
-- anterior: pubis
2.5cm > DC - OC > 1.5cm (DC is bigger)
- Diagnoal conjugate: distance between lower pelvis and sacrum anteriorly
- Obstetric conjugate: narrowest fixed distance through which fetal head must pass vaginally. (at least 11cm)
Pelvic Ligaments
- traditional (dense connective tissue)
-- cardinal:
-- uterosacral:
- unique no significant structual support
-- round: smooth muscle
-- broad: loose areolar tissue
Straited muscles of the Pelvis' walls (Ms. Muscularis)
- pelvic diaphragm: levator ani + coccygeus + piriformis: 3 muscles spanning pelvic floor and sitting on con perineal membrane/body
-- levator ani = illeococcygeus + pubococcygeus + puborectalis: * integral to pelvic floor
--- tonically contracted to prevent pelvic organ prolapse
--- compromised by: multiparity, big kids, abdopressure (coughing/ lifting)
Blood Supply and Surgical risks(Ms. Venosa)
- blood supply:
-- iliac otery
--- anterior branches: interior pudendal, obdurator, inferior gluteal, and pelvicly visceral: uterine/ vesicular/ vaginal/ middle rectal/ obdurator arteries/muscles
--- posterior branches: illiolumbar, lateral sacral and superior/inferior gluteal arterires/muslces
- surgeries
- Hysterectomy risks ureter: often moved in surgery to be closer to transection of infundibulo pelvic ligament or uterine artery
- Tubuligation: external illiac branches: becomes femoral artery; pelvic infrior epigastric artery branches to traverse abdomen, and must be avoided at laporoscic port placement.
Pudendal Nerve location (Ms. Vulvinium) -- not as important
- at level of ischial spine: it crosses prosterior to sacral spinal ligament in close approximation to ligamental attachment to ischeal spine which I shoudl palpate, and inject one cm inferomedially to it to avoid pudendal and inferior gluteal artery
That's a much of help, thanks a lot!
They were talking too fast I couldn't catch up
*6:00am
done
Thank you for having a woman narrator.
