Rotation movement involves turning a body part around its own axis.
The provided reference discusses rotation in the context of body movement, specifically mentioning the head's ability to rotate laterally to either the left or right side. This movement is facilitated by a pivot joint between vertebrae C1. Rotation occurs in both the upper and lower limbs.
Here's a breakdown:
- Definition: Rotation is the movement in which something turns around a central point or axis.
- Examples:
- Head Rotation: The ability to turn your head left or right.
- Limb Rotation: Internal or external rotation of the arm or leg.
- Anatomical Basis: Rotation is made possible by specific joint structures like the pivot joint in the neck.
- Planes of movement: Rotation occurs around the longitudinal axis of the bone.
