Heart Skeleton Diagram. The wall of the heart has three different layers such as the myocardium the epicardium and the endocardium. It provides electrical insulation at the atrioventricular level and fibrous continuity for the leaflets of the mitral aortic and tricuspid valves.
For a cat at rest the average heart rate usually is between 150 and 180 bpm more than twice that of a human which averages 70 bpm. Chambers of the heart the heart is a muscular organ about the size of a fist located just behind and slightly left of the breastbone. Diagram of the skeleton of a cat.
Since these openings and valves structurally weaken the atrioventricular septum the remaining tissue is heavily reinforced with dense connective tissue called the cardiac skeleton or skeleton of the heart.
A domestic cats normal heart rate ranges from 140 to 220 beats per minute bpm and is largely dependent on how excited the cat is. The cardiac skeleton also known as the fibrous skeleton of the heart is a high density singlehomogeneous structure of connective tissue that forms and anchors the valves and influences the forces exerted by and through them. The heart contains 4 chambers.
