Axons and dendrites are tipped by motile growth cones as they grow.
Only batches with more than 95 % motile larvae were used for the experiments.
The majority of worms were slender and highly motile and located in the proximal part of the duodenum.
Oocytes were inseminated with 5 x 104 motile spermatozoa and cultured under the same conditions.
Consider a motile traversing a certain interval, and suppose that the thing in question is generated just as the motion of the motile stops.
Interestingly, the rate of male pronuclear formation was significantly higher in dead spermatozoa than in motile spermatozoa.
The test tube was allowed to stand for 7 min to allow actively motile spermatozoa to swim up into the medium.
Being more motile, the dead cells migrate more readily than the live cells.
