Q. The lumbodorsal fascia is contiguous anteriorly with the:
transversalis fascia
aponeurosis of the transversus abdominis muscle
internal oblique fascia
external oblique fascia
rectus sheath
All three layers of the lumbodorsal fascia join to form a single thick aponeurosis lateral to the quadratus lumborum muscle before extending further anterolaterally, where they are contiguous with the aponeurosis of the transversus abdominis muscles.
