Each renal pyramid and the renal cortex above it is called a renal lobe.

每个肾锥体以及其上方的皮质部分合称为一个肾小叶。

There are also sections of the cortex called renal columns, which extend down into the medulla separating the renal pyramids from one another.

肾柱是肾皮质伸入肾髓质，并分隔肾锥体的部分。

The medulla is made up of 10 to 18 renal pyramids with the base of the pyramids facing the renal cortex and the tips of the pyramids, called renal papilla—or nipples, pointing towards the center of the kidney.

髓质由10-18个肾锥体构成，每个锥体基底面朝向皮质；而尖端称作肾乳头，则朝向肾的中心。
