- A prominent vertical ridge on the inner aspect of the anterior wall is termed the crista terminalis. A corresponding groove on the exterior is termed the sulcus terminalis.

Aug 26, 2013 · The pericardial layers and layers of the heart wall. The third layer of the heart wall is called the endocardium. It is a white sheet of endothelium (squamous epithelium) resting on a connective tissue layer. It is located on the inner myocardial surface and lines the heart chambers.

The limbs of the U are separated by a muscular ridge termed the supraventricular crest. The upper limb, or conus arteriosus (or infundibulum), is the arterial, or outflowing, part of the ventricle, and it ends in the pulmonary trunk. The walls of the conus are usually smooth.
Muscular ridges in the anterior atrial wall and inner surface of the auricle. Muscular ridges in the internal surface of the ventricle. Thin-walled chambers of the heart that receive venous blood. External visible flaps that form by the collapse of the outer wall of a relaxed atrium.
The great veins, the superior and inferior venae cavae, and the great arteries, the aorta and pulmonary trunk, are attached to the superior surface of the heart, called the base. The base of the heart is located at the level of the third costal cartilage, as seen in Figure 17.2.1 17.2. 1.
- Epicardium. Epicardium (epi-cardium) is the outer layer of the heart wall. It is also known as visceral pericardium as it forms the inner layer of the pericardium.
- Myocardium. Myocardium (myo-cardium) is the middle layer of the heart wall. It is composed of cardiac muscle fibers, which enable heart contractions. The myocardium is the thickest layer of the heart wall, with its thickness varying in different parts of the heart.
- Endocardium. Endocardium (endo-cardium) is the thin inner layer of the heart wall. This layer lines the inner heart chambers, covers heart valves, and is continuous with the endothelium of large blood vessels.
Sep 14, 2021 · Inside the pericardium, the surface features of the heart are visible, including the four chambers. There is a superficial leaf-like extension of the atria near the superior surface of the heart, one on each side, called an auricle—a name that means “ear like”—because its shape resembles the external ear of a human (Figure \(\PageIndex ...
This layer is reflected around the roots of the great vessels to become continuous with the visceral layer (also called the epicardium), which covers the surface of the heart, and is firmly applied to it.
