Instant Anatomy

Instant Anatomy presents anatomy and anatomical relationships in a simple, unique, schematic manner to aid the speedy understanding and retrieval of anatomical facts. It shows structures such as nerves and blood vessels in their entirety, unlike the partial, regional presentations given in most textbooks. Covering the major aspects of anatomy, each section presents the relevant structures in double page spreads, with clear, full-colour diagrams on the left and concise text for each structure on the right. This new fifth edition includes more surface anatomy such as new myotome maps, bones of the hands and feet, principles of movement at shoulder and hip and images to clarify the understanding of the inguinal region and the lesser sac of the stomach. Ideal for use alongside a core anatomy textbook, Instant Anatomy is the perfect quick reference guide for medical students, surgeons, radiologists and those in many other specialties. The companion website at www.instantanatomy.net with its podcasts and wide ranging multiple choice questions provide invaluable exam preparation. Robert H.

Coronary Arteries

From: Ascending aorta

To: Myocardium

Right coronary artery. Originates from the anterior aortic sinus. It passes anteriorly between the pulmonary trunk and the right auricle to reach the atrioventricular sulcus in which it runs down the anterior surface of the right cardiac border and then onto the inferior surface of the heart. It terminates at the junction of the atrioventricular sulcus and the posterior interventricular groove by anastomosing with the circumflex branch of the left coronary artery and giving off the posterior interventricular (posterior descending) artery. It supplies the right atrium and part of the left atrium, the sinuatrial node in 60% of cases, the right ventricle, the posterior part of the interventricular septum and the atrioventricular node in 80% of cases.

Left coronary artery. Arises from the left posterior aortic sinus. It passes laterally, posterior to the pulmonary trunk and anterior to the left auricle to reach the atrioventricular groove where it divides into an anterior interventricular (formally left anterior descending) artery and circumflex branches. The circumflex artery runs in the atrioventricular sulcus around the left border of the heart to anastomose with the right coronary artery. The anterior interventricular artery descends on the anterior surface of the heart in the anterior interventricular groove and around the apex of the heart into the posterior interventricular groove where it anastomoses with the posterior interventricular branch of the right coronary artery. The left coronary artery supplies the left atrium, left ventricle, anterior interventricular septum, sinuatrial node in 40% of cases and the atrioventricular node in 20%.

Dominance. In approximately 10% of hearts the posterior interventricular artery arises from the circumflex artery (left coronary) and then most of the left ventricle and interventricular septum are supplied by the left coronary artery. The heart is said to have left cardiac dominance .

Ascending & arch of aorta
Ascending & Arch of Aorta

From: Left ventricle

To: Descending aorta

Ascending aorta. Arises at the vestibule of the left ventricle at the level of the third left costal cartilage and passes upwards and slightly to the right to a point behind the sternum at the level of the manubriosternal joint (second costal cartilage) where it becomes the arch of the aorta. It is enclosed in fibrous and serous pericardium. Anterior to it are the right auricle, the infundibulum of the right ventricle and pulmonary trunk. Posterior, lie the left atrium, the right pulmonary artery and right main bronchus. To the left lie the pulmonary trunk and the left auricle. To the right are the superior vena cava and the right atrium.

Arch of aorta. The arch begins posterior to the manubriosternal joint at the level of the second costal cartilage a
