Head up and back sideward

Question

HiThe head movements are flexion (head tilted forward), extension (head tilted backward), lateral flexion and extension (head up and back sideward) and rotation.--- Does it just mean tilting head to the sides (left, right)?By the way: Does "extension" mean the same as "stretching"?

NewguestThe head movements are flexion (head tilted forward), extension (head tilted backward), lateral flexion and extension (head up and back sideward) and rotation.

--- Does it just mean tilting head to the sides (left, right)? That's the way I take it.

By the way: Does "extension" mean the same as "stretching"? These are scientific descriptions. "Stretching" would have different meanings for scientists and physical trainers/therapists.

There's only one way a person can tilt his own head back. To a PT, any movement taken to its extreme is considered "stretching." Any movement involves multiple muscles. The same movement may involve flexion of some and extension of others. The terms seem to apply here both to the individual muscles and to the "body parts," eg. head, arm, leg, etc.

In the context of your original excerpt, I would not equate extension with stretching. For any given muscle, flexion and extension are opposites. When Arnold flexes his muscles, we're probably not talking about the scientific definition.
