What is the septum of the heart made of?
The atrioventricular septum (AV septum) is the name for the wall of tissue that separates the left ventricle and the right atrium. It is made of membranous tissue and muscle tissue.
What makes the interventricular septum?
The ventricular septum is directed obliquely backward to the right, and curved with the convexity toward the right ventricle; its margins correspond with the anterior and posterior longitudinal sulci. The greater portion of it is thick and muscular and constitutes the muscular interventricular septum.
Which part does interventricular septum have?
The interventricular septum divides the right and left ventricles, running in the plane of the anterior and posterior interventicular grooves. Septation of the ventricles occurs in the fetus within 7 weeks of gestation, achieved by the formation of this embryologically heterogenous structure 6.
What is the structure and function of the interventricular septum?
An important structure that separates the two ventricles is the interventricular septum. Anatomically it is divided into two parts: a thick, muscular part and a relatively thin membranous part. The muscular part of the interventricular septum separates most of the left and right ventricles from each other.

What is the function of interatrial septum?
cardiovascular system. ?a partition known as the interatrial septum; the lower chambers, the ventricles, are separated by the interventricular septum.

What are the constituent parts of the interventricular septum?
The interventricular septum is composed of a muscular and membranous portion, the former subdivided into the following constituent parts: inlet septum extends posteriorly to the cardiac crux, separating the atrioventricular valves. trabecular septum primary structure dividing the anatomic bodies of the left and right ventricles.
Is the ventricular septum a muscle or membrane?
The ventricular septum is a complex anatomic structure dividing the left and right ventricles. Near the aortic valve, the septum is a thin membrane (membranous septum), whereas it is a thick muscle in other parts.
What kind of structure is the sigmoid septum?
Interventricular Septum. The interventricular septum is a complex geometric 3D structure that takes an S curve from apex to base, the so-called sigmoid septum.
Where is the membranous component of the septum?
The comparatively diminutive membranous component is found between the outflow tracts of the left and right ventricles, anterior to the right fibrous trigone, posterior to the right coronary sinus, and continuous with the muscular septum 2.
