3 Νοε 2023 · The pericardium is the membrane that encloses the heart and the roots of the major heart vessels, consisting of an outer fibrous layer (fibrous pericardium) and an inner double serous membrane layer (serous pericardium).
1 Δεκ 2021 · To maintain the general position of the heart within the thorax, the outer fibrous pericardium is widely attached to the central tendon of the diaphragm inferiorly and by the superior and inferior sternopericardial ligaments anteriorly. The heart is securely anchored to the posterior sternal surface by these latter structures .
29 Μαρ 2019 · The pericardium is seen as a linear line (< 2 mm) covering the heart and also the roots of the great vessels (proximal portions of the ascending aorta, pulmonary artery, left pulmonary veins, and superior vena cava) on CT or MRI images [6, 8, 9]. The pericardium consists of outer fibrous and inner serous layers.
Computed tomography (CT) scanning provides a comprehensive anatomic and functional evaluation of the pericardium because of its high spatial and contrast resolution, fast acquisition (5–10 heart beats), multiplanar reconstruction capabilities, and large field of view.
The fibrous pericardium is the most superficial layer of the pericardium. It is made up of dense, and loose connective tissue which acts to protect the heart, anchoring it to the surrounding walls, and preventing it from overfilling with blood.
1 Ιαν 2017 · The image on the left represents an area where the visceral pericardium is in direct contact with the myocardium. Only a thin layer of fibrous tissue (yellow) separates the mesothelial cells (gray blue cytoplasm) from the cardiac myocytes (red sarcoplasm).
There are two layers to the pericardial sac: the outermost fibrous pericardium and the inner serous pericardium. The fibrous pericardium is a conical-shaped sac. Its apex is fused with the roots of the great vessels at the base of the heart.
