On the left lung, immediately above the hilus, is a well-marked curved furrow produced by the aortic arch (Groove for aortic arch), and running upward from this toward the apex is a groove accommodating the left subclavian artery; a slight impression in front of the latter and close to the margin of the lung lodges the left innominate vein ...

2024年1月25日 · The anterior interventricular groove courses along the anterior surface of the heart between the right and left ventricles carrying the left anterior descending artery and great cardiac vein. The posterior interventricular groove travels along the posterior surface of the heart and contains the posterior descending artery and middle cardiac vein.

The coronary sulcus (also called coronary groove, auriculoventricular groove, atrioventricular groove, AV groove) is a groove on the surface of the heart at the base of right auricle that separates the atria from the ventricles.

2012年2月1日 · The epicardial aspect of the left atrium, particularly in the region of the veno-atrial junctions, the interatrial groove, the roof, and the tract of the coronary sinus along the inferior wall, is covered by pads of fatty tissues.

The right atrioventricular groove begins anteriorly and superiorly, behind the ascending aorta. It then descends on the anterior sur- face of the heart and continues around the acute heart...

2022年3月1日 · We report on aortic arch types, aortic and supraaortic vessels diameters, lengths of the supraaortic vessels, incidence of different aortic arch variations. Provided data may be useful by development of new prostheses for this most complex aortic segment.

2019年4月16日 · The aorta emerging from the left ventricle is sandwiched between the right ventricular outflow tract anteriorly and the atria posteriorly. Here, the anterior interatrial groove and the atrial septum lie behind the aorta, separated only by the transverse pericardial sinus.

2020年9月19日 · This article reviews firstly the anatomy and structure of the atrioventricular junction and groove followed by the morphology and variety of accessory pathways that connect directly atrial and ventricular myocardium and those involving the specialized atrioventricular junctional tissues.

Identify the coronary groove (aka coronary sulcus) encircling the heart. This a groove between the atria and ventricles. The coronary groove contains coronary vessels and some amount of fat. Dissection Note: There are two other ‘grooves’ but you will not need to identify them specifically on your specimen.

2018年1月1日 · The atrioventricular or coronary groove of the heart demarcates the borders of the underlying atria from the ventricles. It is a continuous sulcus but it has been described as right and left parts in the following section for the purposes of description.
