APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Rotation is the turning of a bone around its own long axis. It’s the only movement allowed between the first two cervical vertebrae, such as when you shake your head from side to side. Rotation is also common at the hip and shoulder joints. Rotation may be directed toward the midline or away from it.

Detailed explanation-2: -Rotation of the neck or body is the twisting movement produced by the summation of the small rotational movements available between adjacent vertebrae. At a pivot joint, one bone rotates in relation to another bone. This is a uniaxial joint, and thus rotation is the only motion allowed at a pivot joint.

Detailed explanation-3: -Side bend. The side-to-side bending of the spine is also a frontal plane movement, known as lateral flexion, which, for example, occurs during side bend exercises that work the obliques.

Detailed explanation-4: -These movements are called Abduction and ADDuction. The movements of the shoulder in the transversal plane around the longitudinal axis are called external or lateral rotation and internal or medial rotation.
