The muscle anatomy of the back Includes many small muscles that control the small movements at each spinal level. 2. The movements of the spine are flexion, extension, lateral flexion (sidebending) and rotation. Scoliosis is the most common deformity of the vertebral column in pubertal girls (ages 12-15 years). This abnormal extension deformity is often associated with weakened trunk musculature, especially the anterolateral abdominal muscles. In this lesson, we explore the movements of the spine and how they inform teaching. Major function of the spine is generally to protect the very sensitive spinal cord, and its shape is specific in a way most adeqate for compensation of the mechanical trauma. The anterior and posterior longitudinal ligaments (ALL, PLL) extend along the entire length of the spine, primarily supporting the intervertebral joints. Dowager’s hump is a colloquial name for excess thoracic kyphosis in older women resulting from osteoporosis. Latitia Kench They can be very painful and can occur in the neck, mid or low back, affecting everything you do. Colloquially, excess lumbar lordosis is known as hollow back or sway back. • Healthy Posture. Specialised motion occurs at the atlanto-occipital and atlantoaxial joints, which do not contain a disc. All memberships include the Class Builder, a structured process to create, save, edit and print comprehensive classes in less than ten minutes! Their structures are the atlas (C1), the axis (C2) and the dens (also C2). Issues & Conditions. – The vertebrae are connected with joints at the back to enable bending and twisting movements of the spine. The lumbar spine contains 5 vertebrae, labeled L1 to L5, which progressively increase in size going down the lower back. Reviewer: Think your bone knowledge is pretty good? The muscles in the vertebral column provide spinal support and stability and serve to flex, rotate, or extend the spine. Without it, you could not keep yourself upright or even stand up. The spine (also called the vertebral column or spinal column) is composed of a series of bones called vertebrae stacked one upon another. These vertebrae articulate with each other. All of anatomical information about the spine and as well as the clinical relations will be described in this article. From tracings of selected structures, movement is … Structure of the spine In these next two movements you will be moving your spine from side to side. Sitting tall with the weight of your torso evenly distributed between both sit bones, INHALE. You have found content within the Members Only section of Yoga Teacher Central.

Your spine gives your body structure and support. “I would honestly say that Kenhub cut my study time in half.” The 5 sections of the spine or vertebral column are the cervical, thoracic, lumbar and sacrum which includes the coccyx. The cervical and lumbar curvatures are concave posteriorly and convex anteriorly, being referred to as lordoses (singular: lordosis). The following movements of the vertebral column are possible: flexion, extension, lateral flexion and rotation (torsion). Anatomy and Physiology I. Module 10: Joints. They are assisted by gravity and the action of the anterolateral abdominal muscles. Back Muscles. Spinal Regions & Vertebrae. Its structure provides a remarkable combination of rigidity, stability, and flexibility. Habit scoliosis is supposedly caused by habitual standing or sitting in an improper position. As a result, they are termed secondary or acquired curvatures. The vertebral bodies are separated by cushions called intervertebral discs. In the cervical section of the spine there are 7 “cervical” vertebrae. They prevent excessive movement of the vertebral bones.
