What's the difference between ovulist and spermatozoa?
Ovulist
Definition:
(n.) A believer in the theory (called encasement theory), current during the last century, that the egg was the real animal germ, and that at the time of fecundation the spermatozoa simply gave the impetus which caused the unfolding of the egg, in which all generations were inclosed one within the other. Also called ovist.
Example Sentences:
Spermatozoa
Definition:
(pl. ) of Spermatozoon
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) Females were killed at various times after the onset of mating or artificial insemination, oviducts were fixed and sectioned serially, and spermatozoa were counted individually as to their location in the oviduct.
(3) The sensitivity of ejaculated spermatozoa to ouabain (in inhibitor of Na+-K+ ATPase) was determined on 4 consecutive weeks in November, March-April, and July-August.
(4) 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.
(5) The same ratio occurred when zinc (0 to 0.6 mM in citrate buffer) was added to semen or washed spermatozoa.
(6) The sulfhydryl group content of rat epididymal spermatozoa was similar from one cell to another, suggesting little sperm reabsorption in the epididymis.
(7) Hexa- and octasaccharides induced a slight increase in the number of acrosome reacted spermatozoa and disaccharides were ineffective.
(8) In human spermatozoa, the outer acrosomal membrane and plasma membrane contained both types of plasminogen activator (t-PA and u-PA); in addition, t-PA antigen was measured.
(9) To analyze the acrosome reaction induced by the PL, washed or diluted spermatozoa were incubated with or without a PL suspension at 39 C or 41 C. In spermatozoa incubated with the PL suspension, the percentage of spermatozoa lacking acrosomal caps was significantly greater than in controls (without PL).
(10) The migration of human spermatozoa in cervical mucus obtained from women shortly before mid-cycle was studied, using an in-vitro method for horizontal sperm penetration.
(11) The effect of alpha-chlorohydrin on the metabolism of glycolytic and tricarboxylate-cycle substrates by ram spermatozoa was investigated.
(12) Oocytes and spermatozoa are not attacked by the HIV virus but associated lymphocytes or monocytes may be infected.
(13) Three simple equations were determined, by means of which each laboratory will be able to standardize their subject scale for forward progression of the spermatozoa.
(14) The nuclei were isolated from boar spermatid or sperm cells at three distinct stages of spermatogenesis: just before the completion of a maturation process in the testis (late spermatid), immediately after a subsequent transformation into spermatozoa (caput spermatozoon), and after full maturation (cauda spermatozoon).
(15) Cytogenetic analysis revealed hyperhaploid (2.5%) and hypohaploid spermatozoa (1.9%).
(16) Temperature decline through the region of 10 degrees C caused a number of spermatozoa in buffer to undergo a sudden asymmetric bending of the flagellum in the region of the midpiece.
(17) The effect of different lipids on the fertilizing capacity of Bufo arenarum spermatozoa and on acrosome breakdown of Leptodactylus chaquensis spermatozoa was studied.
(18) More spermatozoa were affected and died more quickly as the concentration of D2O increased.
(19) Indirect immunofluorescence studies with four monoclonal antibodies raised against carp spermatozoa revealed that monoclonal antibody WCS 29 stained the outer membranes of primordial germ cells in larvae from 3 days after fertilization.
(20) Neither pH nor composition of liner collection cone had an effect on postthaw acrosomal scores, but the time required for a 50% increase in severely damaged acrosomes was greater for spermatozoa collected in polyethylene than in rubber liner collection cones.
