Anterior abdominal wall is divided into 9 regions with the help of two vertical and two horizontal planes.
The horizontal planes include : –
1. Transpyloric plane (of Adison) :- It lies midway between the suprasternal notch and pubic symphysis. It
passes anteriorly through tips of 9’h costal cartilage and posteriorly through lower border of L, vertebra. Organs present at this level are hilum of kidney, pylorus of stomach, beginning of duodenum, neck of pancreas, fundus of gall bladder and origin of SMA.
2. Trans-tubercular plane :- It connects the tubercles of iliac crests and pass through upper border of L5 vertebra.
The two vertical planes are right and left lateral planes passing through mid inguinal point (also called as mid inguinal plane or midclavicular plane).
