25
Describe the branching pattern of the arteries of the posterior thigh?
Common iliac splits into internal and external iliacs. External iliac keeps traveling and becomes femoral A. (which gives off profunda femoris A.) then becomes popliteal A. (which gives off genicular branches) then posterior tibial A. (which gives off plantar AA. and anterior tibial artery --which then gives off dorsalis pedis) and ends as fibular A.
26
direct vs. indirect inguinal hernias
```
direct= medial to inferior epigastric vessels
indirect= lateral to inferior epigastric mm and goes into the scrotum (most common one)
```
27
contents of inguinal canal
2 NN: ilioinguinal N. and genital branch of genitofemoral N.
males: spermatic cord (ductus deferens, cremaster mm and testicular A&V)
females: round ligament of the uterus
28
describe the branching pattern of the abdominal aorta
aorta splits into R&L common iliacs. Each common iliac splits into internal and external iliacs. Each external iliac goes to become femoral A. (giving off profunda femoris A.)-->popliteal A. (giving off genicular branch AA.)--> splits into anterior and posterior tibial AA. Anterior tib A. becomes dorsalis pedis, posterior tibial A. splits into fibular A. and plantar AA.

what is the special function of popliteus in standing and walking?
It unlocks the knee! It ER the thigh in closed chain so it unlocks the screw home mechanism when standing
