What is the Purpose of the Fibrous Skeleton of the Heart?
The heart is a muscular organ that pumps blood throughout the body. It is composed of three layers: the epicardium, the myocardium, and the endocardium. The fibrous skeleton of the heart is a network of connective tissue that surrounds and supports the heart's chambers and valves. It has several important functions:
- Provides structural support: The fibrous skeleton helps to maintain the shape of the heart and prevents it from becoming misshapen.
- Electrical insulation: The fibrous skeleton prevents the electrical signals that control the heartbeat from spreading outside the heart. This helps to ensure that the heart beats in a coordinated fashion.
- Anchorage: The fibrous skeleton provides anchorage for the heart's valves and blood vessels. This helps to prevent them from becoming dislodged or damaged.
The fibrous skeleton of the heart is a vital part of the heart's structure and function. It helps to keep the heart strong, supported, and electrically insulated.
