Chemoreception plays a central role in the survival and reproduction of many animals in aquatic environments. Fishes use three chemosensory systems, the olfactory system, the diffuse chemosensory system, and the taste (gustatory) system. While these are present in the sea lamprey, a majority of chemosensory research has focused on olfaction. This review summarizes current knowledge of the lamprey chemosensory systems, including stimuli, receptors, neural pathways and behavioural roles of the chemosensory stimuli. A description of the olfactory sensory neurons located deep within the nostril, of synaptic pathways within the brain and of modulatory mechanisms that underly the translation of olfaction to movement are included. The lamprey diffuse chemosensory system may enable solitary chemosensory cells on the skin of the mouth, nostril, gill, and tailfin to function as sentinels for rapid responses to chemical stimuli. While little is known abouth the lamprey taste system, taste buds are located within the pharynx, thus enabling chemosensory responses to material that has entered the body cavity. Knowledge and understanding of function of these three chemosensory systems supports the management of sea lamprey populations.

当前对七lamp鳗化学感应系统的理解

化学接受在水生环境中许多动物的生存和繁殖中起着核心作用。鱼类使用三种化学感应系统:嗅觉系统,弥漫性化学感应系统和味觉(味觉)系统。尽管这些成分存在于海七lamp鳗中,但大多数化学感应研究都集中在嗅觉上。这篇综述总结了关于七rey鳗化学感应系统的当前知识,包括化学感应刺激的刺激,受体,神经通路和行为作用。包括对位于鼻孔深处的嗅觉感觉神经元,大脑内突触途径以及将嗅觉转化为运动的调节机制的描述。七lamp鳗弥漫性化学感应系统可以使口腔,鼻孔,腮,尾鳍可作为前哨,对化学刺激做出快速反应。虽然对七rey鳗味觉系统知之甚少,但是味蕾位于咽部内,因此能够对进入体腔的物质进行化学感应反应。对这三种化学感应系统的功能的了解和理解支持海七lamp鳗种群的管理。
