    Study Notes

    Coronary Artery Dominance

    • The Sino-Atrial Nodal Artery is dependent on the Coronary Artery Dominance.

    Coronary Bypass Operation

    • The Internal Thoracic Artery can be used as a graft in a Coronary Bypass Operation.

    Myocardial Infarction

    • Myocardial infarction is caused by coronary artery occlusion.
    • The Right Coronary Artery accounts for 40-50% of all blockages.

    Angina Pectoris

    • Angina pectoris is caused by myocardial ischaemia.
    • Myocardial ischaemia is a sudden decrease in the flow of blood to the heart, commonly due to the occlusion of a coronary artery.

    Heart Valves

    • The valve pointed to in the diagram is the Pulmonary valve.

    Diaphragm

    • The Diaphragm is innervated by the Phrenic Nerve, which originates from C3, C4, and C5.
    • The Caval Hiatus, Oesophageal Hiatus, and Aortic Hiatus are present at T8, T10, and T12.
    • The Inferior Phrenic Arteries supply the Diaphragm.

    Respiratory Tract

    • The cells lining the trachea are Pseudostratified Ciliated Columnar Epithelial cells.
    • Smoking can damage these cells.

    Larynx

    • The Vestibular Ligament is an alternative name for the False Vocal Cords.
    • The Cricoid Cartilage is the largest cartilage in the Larynx.
    • The Cricothyroid Membrane is commonly penetrated in a Laryngotomy.

    Mediastinum

    • The Mediastinum is the space between the lungs, within the Thoracic Cavity, bounded in front by the Sternum and behind by the Vertebral Column.
    • The Mediastinum can be subdivided by the Sagittal Plane.
    • The Thymus Gland enlarges in Myasthenia Gravis.
    • The Oesophagus and Thoracic Duct pass through the Posterior Mediastinum.

    Thymus Gland

    • The Thymus Gland has a role in the immune system.
