There are eleven artificial (imaginary) layers of the pelvis by dissection. Layer 3 is the layer of rectus sheath.

Layer 3: Layer of rectus sheath below the umbilicus

	Anterior wall of rectus sheath containing External oblique Anterior lamella of internal oblique
	Content Rectus abdominis Inferior epigastric vessels
	Posterior wall of rectus sheath Transversus abdominis aponeurosis Anterior lamella of internal oblique
	Pyramidalis
