Study Notes

Mediastinum and Heart Structure

The mediastinum is an anatomical structure that separates the two laterally placed pleural cavities and lungs.

Mediastinum Subdivisions

The mediastinum has three subdivisions: superior, inferior, and anterior.

Inferior Mediastinum

The inferior mediastinum is located below the level of the fourth thoracic vertebra.

Heart Structure

The fibrous skeleton of the heart is a complex of fibrous tissue that provides a framework for the heart's valves and serves as an electrical insulator.

Conducting System of the Heart

The main function of the conducting system of the heart is to generate and conduct electrical impulses that stimulate the heart to contract and pump blood.
