What's the difference between eyestalk and motile?
Eyestalk
Definition:
(n.) One of the movable peduncles which, in the decapod Crustacea, bear the eyes at the tip.
Example Sentences:

(8) The second factor accelerates ecdysis in nonregenerating animals and appears to be produced in the eyestalks.
(9) Injection of 3-OH-K to the eyestalk-ablated crayfish delayed the onset of the first molt and lengthened the interval between the first and second molts.
(10) A peptide was isolated and purified from sinus glands of the lobster, Homarus americanus, that was able to decrease circulating titers of ecdysteroids and increase the molt interval of eyestalk-ablated juvenile lobsters.
(11) Eyestalk ablation did not significantly reduce the molt cycle duration of regenerating animals.
(12) The concentration of haemolymph sugar and hyperglycaemic activity of eyestalk extract was higher during the night (0 h through 8 h) than that noted in day time (12 h).
(13) During intermolt cycle of juvenile females, mandibular glands in the Crab, Carcinus maenas L., show a cyclical behavior which is disturbed by eyestalk ablation.
(14) The well-known defense response of a crab (laterus merus display, LMD) was easily evoked in Carcinus mediterraneus by striking the cephalothoraxic protogastric region between the eyestalks.
(15) One located outside the eyestalks extends the molt cycle to accommodate regeneration.
(16) Eyestalk-intact, but not de-eyestalked, crabs (Cancer antennarius) given five injections of 5-hydroxytryptamine (5HT, 750 micrograms per injection) in 48 hr showed significant reductions in hemolymph ecdysteroid titers within the first 12 hr which continued through Hour 72; the effect was reversible (Hours 72-144).
(17) NDH synthesis takes place with a time constant of approximately 3 hr in cultured isolated segments of central nervous system, being highest in the eyestalk.
(18) Different areas of the crustacean central nervous system: brain, eyestalks and thoracic ganglionic mass biosynthesize and metabolize histamine.
(19) We describe here the anatomy and physiology of interneurons that connect the brain with the medullae terminales or other eyestalk ganglia.
(20) NDH activity was determined in the various parts of the central nervous system of the crayfish, being highest in the eyestalk, gradually diminishing away from the eyestalk, with a cephalo-caudal gradient, being lowest in the abdominal ganglia.
Motile
Definition:
(a.) Having powers of self-motion, though unconscious; as, the motile spores of certain seaweeds.
(a.) Producing motion; as, motile powers.
Example Sentences:
(1) The proportion of motile spermatozoa decreased with time at the same rate when samples were prepared in either HEPES or phosphate buffers.
(2) All of the strains examined were motile and hemolytic and produced lipase and liquid gelatin.
(3) Whether hen's egg yolk can be used as a sperm motility stimulant in the treatment of such conditions as asthenospermia and oligospermia is subjected for further study.
(4) Forty-five enteropathogenic (enteropathogenic Escherichia coli-like) strains isolated in commercial rabbit farms were subdivided into four biotypes with the help of six carbohydrate fermentation tests, ornithine decarboxylase tests, and motility tests.
(5) Couples applying to in vitro fertilization were admitted into this project when the sperm concentration was greater than 20 million per mL and motility greater than 30 per cent.
(6) Following thawing, the initial motility index (MI) scores of mf cryopreserved by either method were not significantly different from untreated controls; however, over a period of 15 days in culture the MI scores of both cryopreserved groups showed a small but significant overall decline, with the methanol technique producing the lowest scores.
(7) Spontaneous lipid peroxidation in washed human spermatozoa was induced by aerobic incubation at 32 C and measured by malonaldehyde production; loss of motility during the incubation was determined simultaneously.
(8) The freezing procedure increased sperm motility in approximately 30% of samples from both animals.
(9) Liposomes of PC10 rapidly destroyed sperm motility while PC12 acrosome-reacted sperm remained motile for several h. Liposomes of PC with greater than or equal to 14-carbon fatty acyl chains had no effect on the AR or motility of sperm.
(10) In the present study, we have compared the phosphorylation state of the fibronectin receptor in motile neural crest and somitic cells, in stationary somitic cells, and in Rous-sarcoma virus transformed-chick embryo fibroblasts, using immunoprecipitation following metabolic labeling.
(11) Gallbladder mucosal net fluid transport and motility were measured in vivo by a continuous perfusion technique in the anaesthetized cat.
(12) The test is based on the ability of larvae to freely migrate through selected mesh sizes of nylon sieves and the reduced ability of larvae to migrate after preincubation with, and in the presence of, substances that inhibit or reduce larval motility.
(13) The morphological process of spermatogenesis is largely unaffected and motile sperm are produced, but meiocyte aneuploidy is common.
(14) Flow cytometry-derived parameters were essentially time-dependent whereas motility characteristics were primarily temperature-dependent.
(15) There were associated abnormalities of small intestinal morphology, motility, and absorptive function.
(16) The latter were shown to serve Hexamita organisms which exhibit exclusive motility.
(17) It was hypothesized that increased intestinal motility may disturb the absorption of fats and cause the observed difference at least in the Finnish population.
(18) These characteristics are consistent with the proposal that cytoplasmic dynein plays a universal role in retrograde organelle motility.
(19) The fibrosis of the gastric wall with motility disturbances, and the diminution of acid and pepsin production from damage to the glandular elements, would weigh against the addition of a vagotomy to the drainage procedure.
(20) The role of male factor with respect to sperm morphology, progressive motility, and density is studied under in vitro conditions.
