犁鼻器

许多动物，包括老鼠、兔子和猪等，都有一个很特殊的器官，称之为犁鼻器。

Many animals , including mice , rabbits and pigs , have a special organ called the vomeronasal organ ( VNO ) .

所以纵使这些缺乏犁鼻器的小鼠能触碰到大鼠，看到它在呼吸，也并不害怕。

So even though these mice can touch the rat and see it breathing , without the vomeronasal organ system mice don 't respond fearfully .

成年猪的犁鼻器呈梭形，长约3.5cm，中段直径约0.6cm，后端达犬齿的横切面。

The organ is fusiform , the organ size of mature pig is about 3.5 cm in length and 0.6 cm in diameter in the middle segment .

嗅器和犁鼻器是无尾两栖类最重要的嗅化学感受器，对觅食、繁殖及逃避敌害等方面有着重要的作用。

目前，在对啮齿动物嗅觉通讯神经通路的研究中，对主嗅觉系统和犁鼻器系统在动物嗅觉通讯中的作用仍将是人们研究的重点；

Currently , among the research areas in neuro-pathway of olfactory communication in rodents , main olfactory system , vomeronasal system , and their olfactory communication functions are still the focal points .

位于鼻子和嘴之间的犁鼻器能够检测他人的信息素，虽然它的作用机制仍不明确，但信息素能引起性兴奋，提升两性之间的吸引力。

The vomeronasal organ , located between the nose and mouth , usually detects others ' pheromones . Although it is still unclear how they work , pheromones are thought to signal sexual arousal and increase attraction towards appropriate partners .
