With the more superficial forward adductor adductor longus removed medially and pectineus lateral to that still seen, we see the next layer of adductors. The tall thin gracile
hamstring-like adductor the gracilis is most medial. Deep to the missing adductor longus we can see the Adductor brevis which tucks in behind the pectineus a wee bit.
With the more superficial component of the quadriceps removed (rectus femoris), we see the middle plane adductors (gracilis,
adductor brevis, and pectinius - the latter at the edge is both forward and middle plane)
Notice the big vessels take this plane from over the brim of the pelvis to - um - ?? lost it under the medial quad ...
. . . ahhh, that's better. We see the vessels diving under an arch in a big muscle deep to the adductor brevis and longus. This is the adductor magnus.
Both the obturator externus and internus run from the obturator canal to behind the greater trochanter. The pitiformis sits
beneath the roots of the sacrum entering the pelvis to join into the sciatic nerve and a sacral plexus.
Just below the gemelli we find the last small outward rotater, the quadratus femoris. Aside from the joint capsule, the quadratus
femoris is the floor under the sciatic nerve separating it from the hip. The gemelli are a bit upstream and coming from the top of top of the greater sciatic notch is the piriformis.
