A hand slipped behind the heart at its apex can be extended upwards until stopped by a line of pericardial reflection that forms the: Cardiac notch Costomediastinal recess Hilar reflection Oblique pericardial sinus Transverse pericardial sinus
Question
A hand slipped behind the heart at its apex can be extended upwards until stopped by a line of pericardial reflection that forms the: Cardiac notch Costomediastinal recess Hilar reflection Oblique pericardial sinus Transverse pericardial sinus
Solution
The line of pericardial reflection that stops a hand slipped behind the heart at its apex when extended upwards forms the Transverse pericardial sinus.
Here's a step-by-step explanation:
-
The pericardium is a double-walled sac containing the heart and the roots of the great vessels.
-
The pericardial sac has several sinuses formed by its inner and outer layers.
-
The transverse pericardial sinus is a space in the pericardial cavity, posterior to the ascending aorta and pulmonary trunk, and anterior to the superior vena cava.
-
If a hand is slipped behind the heart at its apex and extended upwards, it will be stopped by a line of pericardial reflection. This line of reflection forms the transverse pericardial sinus.
-
The other options mentioned (Cardiac notch, Costomediastinal recess, Hilar reflection, Oblique pericardial sinus) are different anatomical features related to the heart and pericardium, but they do not fit the description given in the question.

A 23-year-old male injured in an industrial explosion was found to have multiple small metal fragments in his thoracic cavity. Since the pericardium was torn inferiorly, the surgeon began to explore for fragments in the pericardial sac. Slipping her hand under the heart apex, she slid her fingers upward and to the right within the sac until they were stopped by the cul-de-sac formed by the pericardial reflection near the base of the heart. Her fingertips were then in the: Coronary sinus Coronary sulcus Costomediastinal recess Oblique sinus Transverse sinus
