30 Οκτ 2023 · The vascular part of the pia mater, which is called the tela choroidea, folds into the cavity of the ventricle and is further covered by ependymal. It contains choroid epithelium, which is simply cuboidal or low columnar epithelium. The extensive folding of the membrane gives the structure an expansive surface area.
Each valve is formed by a group of folds, or cusps, that open and close as the heart contracts and dilates. There are two atrioventricular (AV) valves, located between the atrium and the ventricle on either side of the heart: The tricuspid valve on the right has three cusps, the mitral valve on the left has two.
Ventricular systole: During ventricular systole, the ventricles contract to push blood into the aorta and pulmonary trunk. The pressure of the ventricles forces the semilunar valves to open and the AV valves to close.
11 Ιουν 2024 · Understanding its basic anatomy is crucial to understanding how it functions. This article provides a comprehensive look at the heart's structure with a detailed, labeled diagram and realistic photos, guiding you through each part and its role in the circulatory system.

Atlas of human anatomy: Left ventricle, Left atrium, Anterior papillary muscle
Four coronal sections of L1 with their location indicated by a vertical black line in the upper hemilarynx images, and section number indicated below the histology images. The division of ventricular fold into four quadrants is shown in section 2.
26 Ιαν 2021 · We will use labeled diagrams and lateral views of the brain to learn the anatomy, boundaries, and locations of each ventricle. We will also learn how cerebrospinal fluid is produced, and how it flows throughout the ventricular system, subarachnoid space, and central canal of the spinal cord.
