Talk:nutation

Anatomy
I was reading this book on yoga anatomy and this term was used frequently, I assume it is a reference to physics, but I am wondering how we might elaborate on its usage in relation to stretching and stuff. In particular, it spoke of pelvic nutation of the lowest vertebrae during some bending poses and I was left very confused about what it might mean. DB 11:07, 29 May 2011 (UTC)
 * I think it must mean a slow nodding motion, or (difficult to describe) a slow circular motion of the head (whilst keeping it looking forward). SemperBlotto 11:16, 29 May 2011 (UTC)
