Q

which neurovasculature structure is not part of the femoral sheath?

A

femoral n.

22
Q

intermuscular tunnel for femoral neurovasculature

A

adductor (subsartorial) canal

23
Q

the short head of biceps femoris is grouped with but technically not a hamstring. why not?

A

doens’t extend the thigh, different innervation, different attachment

A

posterior - muscular

anterior - muscular and cutaneous

45
Q

posterior v. anterior divsions of plexuses general rules
