what is the septum
the fibrous skeleton of the heart,summerize
There is an FCT structure within the substance of the heart. This structure is known as the fibrous skeleton of the heart.
This fibrous skeleton serves two general purposes:
• as sites of attachment for muscle tissues
• as supporting structures for the cardiac valves.
Page 2 Fibrous Structures
All of the fibrous structures are continuous and form the fibrous skeleton of the heart.
However they can be divided into three parts as follows:
• The fibrous portion of the interventricular septum.
• The atrioventricular (AV) rings.
• Cylinders at the bases of the great arteries.
Page 3 Fibrous Portion of the Interventricular Septum
The fibrous portion of the interventricular septum - the uppermost portion (also called the membranous portion) of the interventricular septum is a part of the fibrous skeleton of the heart.
Page 4 Atrioventricular Rings
The atrioventricular (AV) rings - each atrioventricular valve of the heart is surrounded by a dense fibrous ring. This ring maintains the valve opening.
Page 5 Cylinders at Bases of Great Arteries
Cylinders at bases of great arteries - each of the semilunar valves of the heart is located within a short fibrous cylinder. This cylinder maintains the structure and function of the valve.
