Thoracic Cage and Thoracic Inlet Professor Dr. Mario Edgar Fernández. Parts of the body The Thorax Is the part of the trunk betwen the neck and abdomen. Commonly the term chest is used as a synonym for thorax, but it is incorrect. Consisting of the thoracic cavity, its contents, and the wall that surrounds it. The thoracic cavity is divided into 3 compartments: The central mediastinus. And the right and left pulmonary cavities. Thoracic Cage The thoracic skeleton forms the osteocartilaginous thoracic cage. Anterior view. Thoracic Cage Posterior view. Summary: 1. Bones of thoracic cage: (thoracic vertebrae, ribs, and sternum). 2. Joints of thoracic cage: (intervertebral joints, costovertebral joints, and sternocostal joints) 3. Movements of thoracic wall. 4. Thoracic cage. Thoracic apertures: (superior thoracic aperture or thoracic inlet, and inferior thoracic aperture). Goals of the classes Identify and describe the bones of the thoracic cage. Identify and describe the joints of thoracic cage. Describe de thoracic cage. Describe the thoracic inlet and identify the structures passing through. Vertebral Column or Spine 7 cervical. 12 thoracic. 5 lumbar. 5 sacral 3-4 coccygeal Vertebrae That bones are irregular, 33 in number, and received the names acording to the position which they occupy. The vertebrae in the upper 3 regions of spine are separate throughout the whole of life, but in sacral anda coccygeal regions are in the adult firmly united in 2 differents bones: sacrum and coccyx. Thoracic vertebrae Each vertebrae consist of 2 essential parts: An anterior solid segment: vertebral body. The arch is posterior an formed of 2 pedicles, 2 laminae supporting 7 processes, and surrounding a vertebral foramen.

Digital Motion X-Ray Cervical Spine
NAME OF PATIENT: CASE STUDY 4 DATE OF REPORT: DATE OF EXAMINATION: REFERRING PHYSICIAN: TESTING FACILITY: Digital Motion X-ray Cervical Spine 1. In the neutral lateral projection: Shows reversal of the cervical lordosis. The integrity of the cervical lordosis and overall condition of the cervical spine is evaluated. The loss of the cervical lordosis may be a result of damage to the posterior longitudinal, capsular or interspinous ligaments. Neutral lateral projection 2. Motion in the neutral lateral projection to full flexion: Is restricted. There is a tilting of C1 laterally. There is an anterolisthesis of C2 on C3. There is increased separation between the spinous processes at C2-C3. This view examines the integrity of the posterior longitudinal ligament demonstrated by a forward (anterior) movement of one vertebrae over the vertebrae below or by the posterior widening of the intervertebral disc space (increased disc angle). Widening of posterior disc space Anterolisthesis The integrity of the interspinous ligament is evaluated in the lateral flexion view. Damage to this ligament results in increased separation of the spinous processes in flexion. Damaged Interspinous Ligament Full flexion projection 3. Motion in the neutral lateral projection to full extension: Is restricted. There is a retrolisthesis of C4 on C5. This view examines the integrity of the anterior longitudinal ligament demonstrated by a backward (posterior) movement of one vertebrae over the vertebrae below or by the anterior widening of the intervertebral disc space (increased disc angle). Retrolisthesis Widening of the anterior disc Full Extension 4. Motion in the oblique flexion projection: Is restricted. There is gapping of the facet joints at C6-C7 bilaterally and C7-T1 bilaterally.

Diagnostic Utility of Increased STIR Signal in the Posterior Atlanto-Occipital and Atlantoaxial Membrane Complex on MRI in Acute C1–C2 Fracture
Published July 6, 2017 as 10.3174/ajnr.A5284 ORIGINAL RESEARCH SPINE Diagnostic Utility of Increased STIR Signal in the Posterior Atlanto-Occipital and Atlantoaxial Membrane Complex on MRI in Acute C1–C2 Fracture X Y.-M. Chang, X G. Kim, X N. Peri, X E. Papavassiliou, X R. Rojas, and X R.A. Bhadelia ABSTRACT BACKGROUND AND PURPOSE: Acute C1–C2 fractures are difficult to detect on MR imaging due to a paucity of associated bone marrow edema. The purpose of this study was to determine the diagnostic utility of increased STIR signal in the posterior atlanto-occipital and atlantoaxial membrane complex (PAOAAM) in the detection of acute C1–C2 fractures on MR imaging. MATERIALS AND METHODS: Eighty-seven patients with C1–C2 fractures, 87 with no fractures, and 87 with other cervical fractures with acute injury who had both CT and MR imaging within 24 hours were included. All MR images were reviewed by 2 neuroradiologists for the presence of increased STIR signal in the PAOAAM and interspinous ligaments at other cervical levels. Sensitivity and specificity of increased signal within the PAOAAM for the presence of a C1–C2 fracture were assessed. RESULTS: Increased PAOAAM STIR signal was seen in 81/87 patients with C1–C2 fractures, 6/87 patients with no fractures, and 51/87 patients with other cervical fractures with 93.1% sensitivity versus those with no fractures, other cervical fractures, and all controls. Specificity was 93.1% versus those with no fractures, 41.4% versus those with other cervical fractures, and 67.2% versus all controls for the detection of acute C1–C2 fractures.

The Structure and Movement of Clarinet Playing D.M.A
The Structure and Movement of Clarinet Playing D.M.A. DOCUMENT Presented in Partial Fulfilment of the Requirements for the Degree Doctor of Musical Arts in the Graduate School of The Ohio State University By Sheri Lynn Rolf, M.D. Graduate Program in Music The Ohio State University 2018 D.M.A. Document Committee: Dr. Caroline A. Hartig, Chair Dr. David Hedgecoth Professor Katherine Borst Jones Dr. Scott McCoy Copyrighted by Sheri Lynn Rolf, M.D. 2018 Abstract The clarinet is a complex instrument that blends wood, metal, and air to create some of the world’s most beautiful sounds. Its most intricate component, however, is the human who is playing it. While the clarinet has 24 tone holes and 17 or 18 keys, the human body has 205 bones, around 700 muscles, and nearly 45 miles of nerves. A seemingly endless number of exercises and etudes are available to improve technique, but almost no one comments on how to best use the body in order to utilize these studies to maximum effect while preventing injury. The purpose of this study is to elucidate the interactions of the clarinet with the body of the person playing it. Emphasis will be placed upon the musculoskeletal system, recognizing that playing the clarinet is an activity that ultimately involves the entire body. Aspects of the skeletal system as they relate to playing the clarinet will be described, beginning with the axial skeleton. The extremities and their musculoskeletal relationships to the clarinet will then be discussed. The muscles responsible for the fine coordinated movements required for successful performance on the clarinet will be described.
