Medullary ray (anatomy)
Middle part of the cortical lobule or renal lobule / From Wikipedia, the free encyclopedia
For the structure found in woody plant stems and roots, see Medullary ray (botany).
In anatomy, a medullary ray (Ferrein's pyramid) is the middle part of a cortical lobule (or renal lobule). Each consists of a group of nephrons in the renal cortex.[1] Their name is potentially misleading, as "medullary" refers to their destination, not their location. They travel perpendicular to the capsule, and extend from the cortex to the medulla. They may be visualised during urography.[1]
