ANTR 350 1st Edition Lecture 8Outline of Last Lecture I. Vertebral columnII. Anatomy of vertebraIII. Regional characteristics of vertebraIV. Joints of the vertebral columnOutline of Current Lecture II. Thoracic cageIII. Ribs IV. SternumV. Joints of thoracic cageVI. Rib dislocationCurrent Lecture-thoracic cage-composed of-T1-T12 vertebrae-12 pairs of ribs-sternum-functions-protect thoracic and some abdominal viscera-aid in respiration by movement of ribs-provide attachment of the pectoral girdle of the upper limb – clavicle attaches tosternum-provide surface area for skeletal muscle attachment-ribs-true ribs: 1-7These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-attach to sternum by individual costal cartilages-false ribs: 8-10-attach to costal cartilage of a superior rib-floating ribs: 11-12-have no anterior attachment-anatomical features-head: articulates with thoracic vertebral body-neck: between head and shaf-tubercle and facet: articulates with the transverse process of thoracic vertebrae-body (shaf): curved flat portion; distal to tubercle-costal groove: groove along inferior border of rib on internal surface; shelters and protects intercostal vein, artery, and nerve-angle: where rib changes direction and begins to curve anteriorly and angle downward-Thoracentesis Procedure: to obtain pleural fluid sample of blood due to a hemothorax-sternum-manubrium-body of sternum-xiphoid process-joints of thoracic cage-costovertebral-gliding type-costotransverse-gliding type-sternocostal-gliding type-manubriosternal-hinge type-costochondral-no allowed movement-rib dislocation-occurs between sternum and costal cartilage-common in contact sports-may put pressure on nearby vessels and nerves-may be able to palpate lump at dislocation
