| Anatomical terminology | |
In anatomy, the medullary ray (Ferrein's pyramid) is the middle part of the cortical lobule or renal lobule, consisting of a group of straight tubes connected to the collecting ducts.
Their name is potentially misleading — the "medullary" refers to their destination, not their location. They travel perpendicular to the capsule and extend from the cortex to the medulla.
