anterolateral abdominal wall
anterior layer – EO & IO
posterior layer - IO & TA
layers interlace at midline – linea Alba

Question 15

Thoracolumbar fascia

Answer 15

posterior layer – superficial TP erector spinae & attached to sp
middle layer – between erector spinae and quadratus lumborum attached to transverse tips
anterior layer – deep to quadratus lumborum, attached to ant. Of TP
