We learned the bones of the front of the skull. We learned the muscles of the brow and forehead. The final aspect to learn is the planes.
First, some information about the image below. This model is known as the "Asaro head," conceived by the painter, teacher and writer John Asaro.

Onward to the planes. Here's a closeup of the model's brow & forehead planes:

Notice how they conform to the curves and landmarks we studied on the skull. If you project the angular planes onto the curved skull, it would look something like this:

See how clear this is when you put all of the elements together!
A quick review:
Hopefully I'm making this information clearer for you and not confusing! Keep in mind that I'm NOT an expert in this area, but simply learning as you are while hopefully providing some insights I've picked up along the way.
Next: the eye & nose muscles.
