What's the difference between copula and copulation?

Copula


Definition:

  • (n.) The word which unites the subject and predicate.
  • (n.) The stop which connects the manuals, or the manuals with the pedals; -- called also coupler.

Example Sentences:

  • (5) In the in copula mating test, 20 and 80 micrograms IT 8-OH-DPAT, significantly reduced ejaculation latency, intromission frequency and intercopulatory interval.
  • (6) The 8-OH-DPAT-induced increase in glucose utilization in the copula pyramis, that is putatively associated with the appearance of the 5-HT behavioural syndrome, was also blocked by BMY 7378, as was the behavioural syndrome.
  • (7) The largest increases occurred in granule cell patches in the contralateral copula pyramidis (Cop P) and pyramis (P), the hemispheric and vermal portions of the eighth cerebellar lobule, respectively.
  • (8) At 40 days of age all animals were gonadectomized, received implants of TP in silastic capsules, and were tested in subsequent weeks for masculine copulatory behavior and ex copula phallic responses.
  • (9) Such grouped receptors may function to indicate position of the worm in copula.
  • (10) There was a partial recovery of emission in copula by the fourth week of treatment, suggesting that a nonadrenergic mechanism had assumed this function.
  • (11) In Experiment 1 a D1 agonist injected into the MPOA increased the number of ex copula erections but decreased the number of seminal emissions.
  • (12) Transition of the tegumental surface from the juvenile to the adult form begins after worms are in copula and have grown to several millimeters in length.
  • (13) Paired males were found to be in copula on 20-34% of observations.
  • (14) The purpose of the study was to determine whether Black inmates could be distinguished from White inmates by their use of the present progressive, final stops, distributive be, remote aspect been, noun plurals, third person singular present tense, possessives, consonant clusters, and the copula.
  • (15) Unpaired males lacked spined tubercles and the development of the spines is considered to occur only when worms are in copula.
  • (16) Metergoline pretreatment also failed to antagonize the RDS-127-induced facilitation of ejaculatory behavior in copula.
  • (17) Both spined and unspined tubercles were found on the dorsal and dorso-lateral surfaces of sexually mature (in copula) male worms.
  • (18) In contrast to seminal emission ex copula, pimozide pretreatment failed to antagonize the RDS-127 facilitation of ejaculatory behavior in copula.
  • (19) Genital reflex ex copula tests were used in order to assess these two responses without the confounding factors of mating behavior.
  • (20) These studies indicate the need for cautious interpretation of data obtained from in vitro analyses of separated male and female mansonian schistosomes, and that such conditions may not reflect in vivo or in copula function.

Copulation


Definition:

  • (n.) The act of coupling or joining; union; conjunction.
  • (n.) The coming together of male and female in the act of generation; sexual union; coition.

Example Sentences:

  • (1) Using allozymes as the genetic probe, data are presented which show that wild Drosophila buzzatii females and males engaged in copulation mate at random.
  • (2) The inhibition is desappears if placed under copulation conditions during a full cycle.
  • (3) Circular cuts which surgically isolated the medial basal hypothalamus (MBH) from the remainder of the brain did not prevent copulation 4 to 24 h later, but did block reflex ovulation.
  • (4) Eight rats of the PCPA group and only two of the vehicle, started to copulate.
  • (5) Incubation of normal pig lymphocytes in serum samples collected from 10 sows immediately before, and at daily intervals after mating with a vasectomized boar significantly elevated the rosette inhibition titre (RIT) of a standard antilymphocyte serum in 6 animals on the first but not on the 2nd and 3rd day after copulation.
  • (6) Duration of copulation in mixed combinations of D. athabasca is determined by the male.
  • (7) In Rhodotorula, peroxisomes are characterized by the same "bean" configuration and paired arrangement imitating "copulation" as mitocondria.
  • (8) On average, copulation lasted 27.2 s and was completed in flight.
  • (9) The surface membrane enzyme activity disappears from the zygote shortly after copulation and at the same time lysosome-like bodies start to appear in the cytoplasm.
  • (10) There was no seasonal fluctuation in copulative activity.
  • (11) Since courtship song increases a females' receptivity to copulation, the frequency of mating within a short observation period was used as a measure of the ability of mutant females to distinguish between singing males and males that were unable to sing.
  • (12) Copulations with other adults males also occurred during all cycle phases, but were most frequent peri-ovulatory.
  • (13) Copulation occurred more often on the occasion of the first attempt by the male.
  • (14) In the second experiment, intact females copulated twice with a male: once when they were able to hear and once when they were temporarily deafened with a medical ear mold.
  • (15) The gene products are secreted into the male duct and transferred to the female copulant during copulation.
  • (16) Pregnant C3H mice were exposed to teratogenic doses of cyclophosphamide (CPA), on the 11th day after copulation.
  • (17) Thiazide-type diuretics also produce erectile dysfunction in rats and interfere with normal copulation.
  • (18) Morphine administered rats showed a loss of weight, hypertrophy of the adrenals, decreased weight of accessory sex organs, low sperm count, and decreased copulation rate.
