Pre-excitation Syndrome - Pathophysiology
... Normally, the atria (chambers taking venous blood) and the ventricles (chambers pumping blood towards organs) are electrically isolated, and electrical ... allow the atria to contract before the ventricles ... However, there is no such delay in the abnormal pathway, so the electrical stimulus passes to the ventricle by this tract faster than via normal atrioventricular/bundle of His system, so the ventricles are ...

Lateral Ventricles - Development
... The lateral ventricles, similarly to other parts of the ventricular system of the brain, develop from the central canal of the neural tube ... Specifically, the lateral ventricles originate from the portion of the tube that is present in the developing prosencephalon, and subsequently in the ... During the first trimester of pregnancy the central canal expands into lateral, third and fourth ventricles, connected by thinner channels ...
