Study Notes
Learning Objectives
- Understand the divisions of the mediastinum: anterior and middle mediastina
- Identify boundaries and contents of the anterior and middle mediastina
- Describe the coronary arteries and explain the conducting system of the heart
- Recognize the chambers of the heart and their distinct features
- Explain the structure and function of the pericardium
- Familiarize with the proximal parts of the great vessels
Heart Anatomy
- Heart has quadrilateral shape, oriented posteriorly
- Anterior (sternocostal) surface includes:
- Right atrium and part of the left ventricle
- Pectinate muscles present on the walls of the atria, resembling comb teeth
- Right auricle functions as a conical muscular pouch to assist atrial contractions
Great Vessels and Cardiac Structures
- Key vessels include large structures attached to the specific chambers:
- Superior vena cava: drains blood from the upper body
- Inferior vena cava: drains blood from the lower body
- Pulmonary arteries: right and left facilitate oxygen-poor blood to lungs
- Pulmonary veins: right and left return oxygen-rich blood from lungs to the heart
- Arch of aorta: major artery carrying oxygenated blood from the heart to the body
Pericardium
- Functions to protect and lubricate the heart, preventing friction during heartbeats
- Structurally composed of fibrous and serous layers:
- Fibrous pericardium provides support and prevents over-expansion
- Serous pericardium includes parietal and visceral layers, enclosing the heart
Relevant Resources
- Gray's Anatomy for Students references on heart and pericardial anatomy
- Netter’s Atlas utilized for visual depiction of cardiac structures and their spatial relationships
