Arrow denotes progressive motion of sperm and inset shows a front view of the trajectory. In panel (b), sperm from deer mouse form a sperm train using apical hooks on sperm heads to loop around other flagella. This is one type of collective or cooperative behavior observed in sperm.

WebA straight-line path from the first to last position of a sperm head is plotted, and velocity along this trajectory is termed straight line velocity (VSL; mm/s). For each centroid location there is a deviation from the average path, and this is termed the amplitude of lateral head displacement (ALH; mm). Webtrace the 3D trajectories of multiple sperm at the same time (Jikeli et al., 2015; Su et al., 2012, 2013). Observed sperm trajectories can vary form planar to quasi-planar, and to helical, possibly forming a chiral ribbon or a agelloid curve, as shown in Figure 1 (Smith et al., 2009a; Woolley & Vernon, 2001; Woolley, 2003; Su et al., 2012, 2013). family dental practice moss side https://redrockspd.com
