Description:

Description: English: Possible entrance of a bubble through an incurrent ostium in the heart of the grasshopper Schistocerca americana I. Movie depicts the grasshopper's 5th abdominal segment in lateral view, with dorsal oriented upward and anterior to the right. Field of view is 1.3 × 0.9 mm. The dorsal edge of the abdomen can be seen near the top. The diagonal lines in the upper left corner are margins of the x-ray transparent Kapton tube. In this sequence, the bubble of interest appears to begin its trajectory outside the heart in the pericardial sinus; it moves dorsally and then anteriorly to the ostium opening; it then enters the heart and is swept anteriorly along with the flow. Although we interpret this trajectory as a heart entrance event, other possibilities remain. Date: 2009. Source: Lee W, Socha J (2009).
