一、鱼类的化学感受作用和化学感受器鱼类的化学感受器接受内,外环境的化学刺激而产生感觉的过程叫做化学感受作用。化学感受器是水生动物感受水环境中化学信息的专门器官。它们由特化了的细胞群组成。就鱼体来说,按其分布的部位不同,有内感受器和外感受器两类。它们的功能都是将化学刺激的信息转换成生理信息—感受器电位。在鱼类的行为学研究中,一般所指的化学感受器,多数是指分布在鱼的体表和口腔粘膜等处的外部化学感受器。包括了鱼类的嗅觉和味觉感 First, the chemical perception of fish and chemoreceptors The chemical receptors that accept the chemical stimuli inside and outside the environment are called chemoreceptors. Chemoreceptors are specialized organs of aquatic animals that experience the chemical information in the aquatic environment. They consist of specialized cell populations. For fish, according to the distribution of different parts, there are two types of receptors and external receptors. Their function is to convert chemically stimulated information into physiological information - the receptor potential. In the behavioral research of fish, chemisensors generally refer to external chemoreceptors distributed on the surface of fish and oral mucosa. Includes the sense of smell and taste of fish
