They generally only have one axis of symmetry, and by rotating an oval along this axis, the surface of revolution we create is called an " ovoid" .

它们常只有一个对称，过沿该旋转椭圆形，我们创建的旋转表面被称为卵形。

So if you take, on average, a group of top golfers, you'll notice that their spines, that the disc shape, if we were to cut through, which is a transverse scan on an MRI, the discs are more ovoid.
