aponeurosis of the transversus abdominis muscle

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.
