Summary

[edit]
Description
English: Oscillatory hemolymph flow in the heart of the grasshopper Schistocerca americana II. Movie depicts the grasshopper's 6th 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 running from upper left to lower right are margins of the x-ray transparent Kapton tube. This video demonstrates a second sequence in which the local heart flow is oscillatory, with no net transport anteriorly or posteriorly. Additionally, the primary bubble movement in the dorsal heart follows a diagonal trajectory (left side), evidencing a bend in the heart tube.
