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
