The renal papilla project into minor calyces which join together to form major calyces which funnel into the renal pelvis.

突盏，每2-3个盏合成大盏；2-3个大盏合并形成漏斗形的盂。

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个锥体构成，每个锥体基底面朝向皮质；而尖端称作，则朝向的中心。

然后我们看得更详细一点，你可以看到单个突出现， 那里有脊，所以它是突上的突等等。
