Study Notes
Heart Location
- Located within the middle mediastinum
- Heart apex slightly deviates to the left side
- Heart sits between both lungs
Ventricle Structure
- Two ventricles, right and left, are separated internally by the interventricular septum
- Ventricles are also separated externally by the anterior and posterior interventricular grooves
Blood Circulation within the Heart
- Contains the main trunks of the right and left coronary arteries
- Contains the circumflex branch of the left coronary artery
- Contains the coronary sinus
Anterior Inter-ventricular Groove
- Situated between the two ventricles
- Found on the sternocostal surface
Sulcus Terminalis
- Faint, barely noticeable groove
- Located on the external surface of the right atrium, between the superior vena cava (SVC) and inferior vena cava (IVC)
- Marked internally by the crista terminalis
- Extends from the right sixth costal cartilage to the right third costal cartilage
- Then from the right third costal cartilage to the left second costal cartilage
- Finally, from the left second costal cartilage to the left fifth intercostal space
