The force generated by a detergent-extracted reactivated bull sperm flagellum during an isometric stall was measured with a force-calibrated glass microprobe. The average isometric stall force from 48 individual measurements was 2.5 +/- 0.7 x 10(-5) dyne (2.5 +/- 0.7 x 10(-10) N). The force measurements were obtained by positioning a calibrated microprobe(More)
Cilia in many organisms undergo a phenomenon called ciliary reversal during which the cilia reverse the beat direction, and the cell swims backwards. Ciliary reversal is typically caused by a depolarizing stimulus that ultimately leads to a rise in intraciliary Ca++ levels. It is this increase in intraciliary Ca++ that triggers ciliary reversal. However,(More)
