anterior fascial layer of transversus abdominis muscle

anterior fascial layer of transversus abdominis muscle

An obsolete term that formerly dignified the aponeurosis of the transverse muscle of the abdomen (musculus transversus abodominis), which passes transversely to end in the linea alba; the superior portion blends with the posterior lamina of the sheath of the rectus muscle of the abdomen (lamina posterior vaginae musculi recti abdominis), while the inferior fibres form part of the conjoint tendon.
