The horizontal planes are also called
transpyloric planes
Extent of the transpyloric plane
It extends midway between the jugular or suprasternal notch and pubic symphysis.
It then passes through the pylorus of the stomach and corresponds to the lower border of L1 and the trans tubercular plane.
Transtubercular plane passes through what
It passes through the tubercles
of the iliac crest and the body of the L5 vertebrae.
