Study Notes
Lymphatic Drainage of the Pericardium
- Lymphatics draining the lateral parts of the pericardium pass to the anterior mediastinal, tracheobronchial, lateropericardial, prepericardial, and posterior mediastinal (juxtaesophageal) lymph nodes.
Heart - Location and Size
- The heart is located anterior to the 5th to 8th thoracic vertebrae.
- It is approximately the size of a fist and weighs 250-300 grams.
Heart - Anatomical Position and Orientation
- It is quadrilateral and directed posteriorly.
- Lies opposite the middle thoracic vertebrae (5-7), separated from them by the descending aorta, esophagus, and oblique sinus of the pericardium.
Heart - Inferior Boundary
- Bounded inferiorly by the posterior ventricular part.
Heart - Ventricles
- The right two-thirds of the heart is formed by the right ventricle.
- The left one-third of the heart is formed by the left ventricle.
- The ventricles are separated by the anterior interventricular groove, which lodges the Anterior interventricular artery (branch of the left coronary) and the Great cardiac vein.
Surface Anatomy of the Heart: Superior Landmarks
- Superior right point: Upper border of the 3rd right costal cartilage, one inch from the midline.
- Superior left point: Lower border of the 2nd left costal cartilage, 3cm to the left of midline.
