What is left and right lateral flexion?

What is left and right lateral flexion?

For the vertebral column, flexion (anterior flexion) is an anterior (forward) bending of the neck or body, while extension involves a posterior-directed motion, such as straightening from a flexed position or bending backward. Lateral flexion is the bending of the neck or body toward the right or left side.

What muscles cause lateral flexion?

All trunk flexors and extensors can produce lateral flexion when acting unilaterally. The major muscles involved are the rectus abdominis, external and internal obliques, erector spinae, semispinalis thoracis, latissimus dorsi, deep posterior spinal muscles, quadratus lumborum, and psoas.

What is lumbar lateral flexion?

Lumbar Spine. Lateral flexion is side bending in the frontal/ coronal plane. The quadratus lumborum, oblique abdominals, and erector spinae are considered the primary lateral flexors. Note that the internal and external obliques on the same side work to produce the same motion.

What causes lateral flexion and extension of the spine?

The origins and insertions of the various deep back muscles overlap extensively, and when they contract, entire regions of the vertebral column can be moved simultaneously (causing extension or hyperextension). When these muscles contract on only one side of the vertebral column, lateral flexion occurs.

Is lateral flexion the same as abduction?

Abduction – Movement away from the midline of the body (in the frontal plane). Adduction – Movement toward the midline of the body (in the frontal plane). Lateral Flexion – Displacement of the trunk away from the midline in the frontal plane (in the frontal plane).

What joints allow lateral flexion?

Apophyseal joints: It is formed by articulation of inferior facets of vertebrae and superior facet of adjacent vertebrae. Direction and range of movement of these joints depend on orientation of articular facets. These joints allow flexion, extension, rotation and lateral flexion.
