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.
