Detailed explanation-1: -The thin partition that separates the first and second ventricles is the septum pellucidum.

Detailed explanation-2: -The interventricular septum, also known as the ventricular septum, refers to the triangular wall of cardiac tissue that separates the left and right ventricles (i.e., the lower chambers) of the heart. The entire interventricular septum can be further divided into two parts: a muscular portion and a membranous portion.

Detailed explanation-3: -The ventricular septum is a thick structure comprised of discrete muscular bands that separates the left and right ventricles, and contributes to cardiac function.

Detailed explanation-4: -The first and second ventricles are lateral ventricles. These C-shaped structures are located on each side of your cerebral cortex, the wrinkly outer layer of your brain. The third ventricle is a narrow, funnel-shaped structure situated between your right and left thalamus, just above your brain stem.
