Study Notes
Intervertebral Joint and Ligaments
- The intervertebral joint between the vertebrae is a cartilaginous joint.
- Posterior longitudinal ligament (PLL) covers the posterior surfaces of the vertebral bodies and the intervertebral discs.
- Ligamenta flava assist in limiting backward bending and support the anterior convexity in the lumbosacral area.
- The anterior longitudinal ligament extends from the occipital bone to the sacrum along the anterior surfaces of vertebral bodies.
Vertebral Body Structure
- Articulations of vertebral bodies are classified as symphysis joints.
- The transverse ligament of the atlas connects the atlas (C1) with the occipital bone.
- A pivot joint is formed between the atlas and the occipital bone, allowing head rotation.
Rib and Vertebra Articulations
- The costovertebral ligaments divide the joint between the rib head and the vertebra into two cavities.
- Uncovertebral joints, formed from uncinate processes, are located between the cervical vertebrae.
- The costovertebral ligament connects the head of each rib with the side of the bodies of two adjacent vertebrae.
- The costotransverse ligament connects the rough surface on the back of the rib's neck with the anterior surface of the transverse process.
- The head of typical ribs forms a synovial joint with the facets on the thoracic vertebrae bodies.
Spinal Disorders and Posture
- Degenerative changes in the anulus fibrosus of the intervertebral discs can lead to herniated discs.
- The ligamentum flavum connects the laminae of adjacent vertebrae and contributes to maintaining upright posture.
- The supraspinous ligament extends consonantly upward to the ligamentum nuchae.
Joint Movements and Functionality
- The atlantoaxial joint allows for skull rotation and is supported by lateral articular capsules.
- Sternal ends of true rib cartilages connect to the sternum via synovial joints.
- Sternocostal joints permit slight movement in multiple directions.
- Costochondral articulations are classified as synarthroidal joints, permitting minimal movement.
Rib Movements
- Joint movements that raise ribs laterally involve simultaneous action of costotransverse and costovertebral joints.
- The motion of the sternocostal joint pulling the sternum superiorly is referred to as pump-handle motion.
Ligament Overview
- Intertransverse ligaments are situated between transverse processes in the spine.
- Zygoapophysial joints are classified as synovial joints, supported by several ligaments.
- There are two atlantoaxial joints, which assist in head rotation.
- The transverse ligament of the atlas holds the dens of the axis in place.
- The alar ligaments connect the sides of the dens to the occipital bone, preventing lateral rocking of the atlas.
Atlantooccipital Joint Movement
- The atlantooccipital joint permits flexion, extension, and limited lateral movements, primarily supported by anterior and posterior atlantooccipital membranes.
Uncovertebral Joints
- Uncovertebral joints, also known as Luschka's joints, facilitate flexion and extension within the cervical region and are found between adjacent uncinate processes from C1 to C7.
