Vortex formation in the embryonic heart

Meeting Abstract 82.1  Sunday, Jan. 6  Vortex formation in the embryonic heart MILLER, L. A.; University of North Carolina, Chapel Hill lam9@email.unc.edu The vertebrate heart first forms as a simple tube that pumps blood at low Reynolds numbers (10-2 – 10-1) without the use of valves. As the heart develops, the atrium and ventricle bulge out from […]

Biomechanics of the Pharyngeal Musculature in Stenostomum virginianum (Catenulida)

Meeting Abstract 82.5  Sunday, Jan. 6  Biomechanics of the Pharyngeal Musculature in Stenostomum virginianum (Catenulida) SMITH III, Julian P.S.*; DAVIS III, Harold; Dept of Biology, Winthrop University smithj@winthrop.edu In culture, Stenostumum virginianum feeds readily on Paramecium spp., which it captures by rapidly flaring the pharyngeal lumen, sucking in the prey, as originally described by Nuttycombe. High-speed videomicroscopy […]
