Action: Depresses hyoid bone; fixes hyoid during opening of mouth Origin: superior border of scapula Insertion: hyoid bone Innervation: cervical spinal … The discs are named for the vertebra located immediately above the disc; that is, the T6 disc is located between the T6 and T7 vertebrae. With the exception of the cervical vertebrae, the hyoid bone is the only bone located in the anterior neck. The axial skeleton forms the upright axis of the body. Unlike other bony structures, the hyoid bone does not directly articulate with other bones. The sternum (or breastbone) is a flat bone located at the anterior aspect of the thorax.It lies in the midline of the chest and has a ‘T’ shape. Hyoid bone (fig. •Pharynx ends; esophagus begins. T2 superior angle of scapula. The entire superior edge of the thyroid cartilage is attached to the hyoid bone by the thyrohyoid membrane. The purpose of this study is to investigate the predictive value of the hyoid horizontal positional change on the severity of dysphagia and dysphonia (PDD) after anterior cervical discectomy and fusion (ACDF) comparing pre-vertebral soft-tissue thickness (PVST). 42-23) The hyoid bone lies in the front of the neck at the upper limit of the larynx. vertebral level located just superior to the hyoid bone of the neck; serves as a point of muscle attachment C4 vertebral level with the superior portion of the thyroid cartilage and marks the beginning of the larynx The hyoid bone is located between the chin and the thyroid cartilage. This point relates to level of the hyoid bone on a computed tomographic (CT) scan. by pammie12, Sep. 2015. It’s located at the level of the third vertebra, between the jaw and the thyroid cartilage. Sixth and seventh thoracic vertebrae. It presents a body and paired greater and lesser horns. Twelfth thoracic vertebra. Level II: Upper jugular nodes (Subdigastric nodes) - around the upper third of the internal jugular vein and adjacent accessory nerve. VERTEBRAL LEVEL LANDMARKS & STRUCTURES; C1: Spinal root of accessory nerve crosses transverse process of atlas: C2: Superior cervical ganglion: C3: Body of hyoid bone: C4: Superior border of thyroid cartilage Bifurcation of common carotid arteries: C6: Cricoid cartilage Larynx ends and trachea begins Pharynx ends and oesophagus begins ACDF patients … Hyoid bone is a solitary bone localized at the level of cervical 3 vertebrae, connected to the adjacent bone structures with muscles and tendons. Moving upward along the midline of the neck from its base, the first cartilage you can feel is the cricoid cartilage. These measurements were repeated for the hyoid bone as a control for each patient. Ignore words. •Larynx ends; trachea begins. ... in the 8th or 9th intercostal spaces intercostal spaces. Vertebral Level Landmark Internal Significance. T12 is the first blade-like spinous process (same as the lumbars). in the anterior portion of the neck at the level of the C3 vertebra. The hyoid bone was located more inferiorly at all stages in the OBG than in the CG. The thyroid cartilage is found between the levels of the C4 to C5 vertebrae. Above this is the thyroid cartilage, and above the thyroid cartilage sits the tongue bone. The hyoid serves as the base for the tongue above, and is attached to the larynx below and the pharynx posteriorly. Ignored words will never appear in any learning session. C6 Cricoid cartilage. Intervertebral discs are located between the anterior portions of the movable vertebrae and between L5 and the sacrum. The Hyoid Bone and Vertebral Column . This is a retrospective observational study with prospectively collected data at a single academic institution. The oblique line is a line on the thyroid cartilage.
