The movement parameters of a sea urchin sperm flagellum can be manipulated mechanically by applying various modes of periodic vibrations to the sperm head held by suction in the tip of a micropipette. The beat frequency of the flagellum readily synchronizes with the frequency of the externally impos

## Abstract In this study we used Triton Xโ€100 extracted sea urchin spermatozoa to investigate the mechanical behavior of the basic 9+2 axoneme. The dynein motors were disabled by vanadate so that the flagellum is rendered a passive structure. We find that when a proximal portion of the flagellum i

Previous work has shown that the dynein from axonemes of sea urchin sperm consists of two distinct fractions which differ substantially in their extractability by salt. Upon gel electrophoresis of whole demembranated axonemes solubilized with sodium dodecyl sulfate, the dynein fraction shows two clo

## Abstract Sea urchin eggs take up Ca for 10 min following insemination (determined as uptake of ^45^Ca from the SW (3)). Although 90% of this uptake occurs after the beginning of the cortical reaction and may represent external binding of Ca to the egg surface coats, there is a brief phase of upt
