What is the side flexion?

Side flexion is an anatomical term to move bending to the side of the waist. Alternatively known as side bending or side bending flexion of the trunk, it can refer to the movement of the entire spine in the side direction, only the neck or segment of the spine. The side flexion is made possible by cartilage joints between the adjacent vertebrae in the spine, which, unlike most moving joints of the body, do not work as individual units of movement, but as part of the movement segments producing movement throughout the spine. Similarly, it makes it easier for individual muscles, but by groups of closely situated muscles that shoot at the same time. This is because the lateral flexion affects the whole part of the spine, not just the two adjacent vertebrae. The side bending of the waist includes movement in the thoracic and lumbar spine; The head of the head requires the connection of most of the cervical spine. The smallest movable unit, which is two adjacent stacked vertebrae and cartilage between them, is known as the spinal cord segment or a functional backbone unit. The side flexion depends on the coordination of several movementh segments.

Each individual segment of movement is capable of varying degrees of lateral flexibility. At the same time, the greater degree of lateral flexion than in individual segments is visible with more segments with bending side, while the cervical spine has the latest flexibility and the least lumbar spine. For example, between L1 and L2, the first two lumbar vertebrae are approximately six degrees of lateral flexibility; The same is observed between L2 and L3. L3 and L4 have a larger range of motion - eight degrees - WHILE six degrees are possible between L4 and L5, lower lumbar vertebrae.

Side flexion would not be possible if not for many trunk and neck muscles. The muscles that produce this movement tend to come on the side of one vertebra or vertebrae and attach to the side of another vertebra or vertebra else else in the spine, so infecting these muscles shortens the spine along one side and pulls the trunk laterally. Muscles of the Erecto GroupR spinae deep in the back include several vertical segments that tend to correspond to the cervical, thoracic or lumbar region.

Longissimus cervicis has fibers originating in transverse or side processes T1 to T5 in the thoracic spine. These fibers rise and connect individually to the same C2 processes via C6 in the cervical spine. These muscles also create lateral flexion only in one -sided shooting or only on one side. When bilaterally firing instead, you expand the spine and help in maintaining an upright posture.
