Only spherical should be confusing. Any point on a plane can be described by the distance form the origin and the angle. Adding the 3rd dimension, it's the same but we slide over z: cylindrical. Spherical is cancerous with those two angles, but it's still logical. Shit can be generalized to n dimensions for differential geometry induced tumors.

Just take a look at pic and note that the second angle only needs to take values between 0 and pi in order to describe every point on the sphere.
