Something I learned years ago in martial arts, is how to accurately describe which plane or axis something is rotating along. The terminology was useful during instruction, and may be useful to designers seeking to describe how something pivots relative to the human body.
Listen beautiful relax classics on our Youtube channel.
Basically:
Sagittal plane: Bicycle wheel.

Coronal plane: Steering wheel.

Axial plane: Pottery wheel.

I hope that somehow comes in handy!
