Sacral plexus goes from what to what
S1-S4
the 5 muscles of the medial compartment of the thigh (think the sides of the thigh)
- gracilis
- adductor longus
- adductor brevis
- adductor magnus (oblique fibers)
- obturator externus
ADD & GO!
B. There are 4 muscles that comprise the posterior compartment of the thigh:
This compartment runs from the buttock to the posterior aspect of the knee and is separated from the extensor compartment by the lateral intermuscular septum.
- biceps femoris
- semitendinosus
- semimembranosus
- adductor magnus (vertical fibers)
posterior compartment of thigh is innervated by (*note the exception)
THE SCIATIC NERVE
(this includes vertical fibers of adductor Magnus)
exception - bicep femoral short head = common peroneal nerve
