Flagellar Radial Spoke Protein 2 Is a Calmodulin Binding Protein Required for Motility in \u3cem\u3eChlamydomonas reinhardtii\u3c/em\u3e [PDF]

open access: yes, 2004
Genetic and morphological studies have revealed that the radial spokes regulate ciliary and flagellar bending. Functional and biochemical analysis and the discovery of calmodulin in the radial spokes suggest that the regulatory mechanism involves control

Ultrastructures of spermatozoon tail in rice water weevil, Lissorhoptrus oryzophilus Kuschel (Coleoptera, Curculionidae)

open access: yes浙江大学学报. 农业与生命科学版, 2008
Ultrastructures of spermatozoon tail in the rice water weevil, Lissorhoptrus oryzophilus, were observed via transmission electron microscopy at selected sperm developmental stages with the aim at clarifying spermiogenesis in this weevil.

Structure and behaviour of the sperm terminal filament [PDF]

open access: yes, 1982
Light- and electron-microscopic observations of Ciona and Lytechinus spermatozoa show a thin terminal filament at the distal end. The terminal filament is 5-6 microns long and contains the two central microtubules and a variable number of A-tubule ...

Modelling the Fluid Mechanics of Cilia and Flagella in Reproduction and Development

open access: yes, 2012
Cilia and flagella are actively bending slender organelles, performing functions such as motility, feeding and embryonic symmetry breaking. We review the mechanics of viscous-dominated microscale flow, including time-reversal symmetry, drag anisotropy of
