The pars interarticularis, or pars for short, is the part of a vertebra located between the inferior and superior articular processes of the facet joint. [1] [2] In the transverse plane, it lies between the lamina and pedicle. In other words, in the axial view, it is the bony mass between the facets that is anterior to the lamina and posterior ...
Articular processes spring from the junctions of the pedicles and laminæ, and there are two right and left, and two superior and inferior. These stick out of an end of a vertebra to lock with a zygapophysis on the next vertebra, to make the backbone more stable.
However, in common, literary, and historical usage, arm refers to the entire upper limb from shoulder to wrist. This article uses the former definition; see upper limb for the wider definition. [8] In primates, the arm is adapted for precise positioning of the hand and thus assist in the hand's manipulative tasks. The ball and socket shoulder ...
The lumbar vertebra consist of a body, pedicle, lamina, pars interarticularis, transverse process, spinous process and superior and inferior articular facets, which form joints that link the vertebrae together. When examining the vertebra, the pars interarticularis is the bony segment between the superior and inferior articular facet joints ...
Spondylolysis is a defect in the pars interarticularis of the vertebral arch. In most cases this occurs in the lowest of the lumbar vertebrae (L5), but may also occur in the other lumbar vertebrae, as well as in the thoracic vertebrae.
Hakalo and Wronski (2008) showed the benefits of operative treatment such as using transoral C2-C3 discectomy with plate-cage stabilization or posterior direct pars screw repair for the reducing and healing process. [9] In deliberate or suicidal hanging, asphyxia is much more likely to be the cause of death due to associated prevertebral swelling.
The Absolute Best Arm To Get Vaccines In, According to Research and Experts Dr. Handel says scientists are still hashing that out, and recent research has produced conflicting results.
The lateral intermuscular septum extends from the lower part of the crest of the greater tubercle of the humerus, along the lateral supracondylar ridge, to the lateral epicondyle; it is blended with the tendon of the deltoid muscle, gives attachment to the triceps brachii behind, and to the brachialis, brachioradialis, and extensor carpi radialis longus muscles in front.
