How many degrees of rotation do the bones in your body have?

Answer 1

Depends which bone, or more importantly, which joint you are referring to.

The atlantoaxial joint (highest 2 vertebrae is neck) allow alot of rotation, similarly, the radiohumeral joint (one of the joints at the elbow) has a fair bit of rotation. Alternatively, lower lumbar intervertebral joints have little rotational component. Thus the question is much too broad to provide an appropriate answer.
