**These structures are visible grossly and are the region of the medulla which appears triangular in cross section. They are actually cone shaped and the pointed part which faces towards the renal pelvis is termed the apex and the part against the cortex the base.

* In some species the kidneys are described as '''multipyramidal''' this means they have multiple lobes and pyramids.  Others are described as '''unipyramidal''' meaning they only have one lobe and pyramid.
