Abstract

Little is known about the chemosensory system of gustation in sea lampreys, basal jawless vertebrates that feed voraciously on live prey. The objective of this study was to investigate taste bud distribution and chemosensory responses along the length of the pharynx in the sea lamprey. Scanning electron microscopy and immunocytochemistry revealed taste buds and associated axons at all six lateral pharyngeal locations between the seven pairs of internal gill pores. The most rostral pharyngeal region contained more and larger taste buds than the most caudal region. Taste receptor cell responses were recorded to sweet, bitter, amino acids and the bile acid taurocholic acid, as well as to adenosine triphosphate. Similar chemosensory responses were observed at all six pharyngeal locations with taste buds. Overall, this study shows prominent taste buds and taste receptor cell activity in the seven pharyngeal regions of the sea lamprey.

海鳗咽味蕾的分布和化学感应反应。

人们对海灯鱼的味觉化学感觉系统知之甚少。海灯鱼是一种无颌脊椎动物，贪婪地捕食活的猎物。本研究的目的是调查海灯鱼咽部的味蕾分布和化学感觉反应。扫描电子显微镜和免疫细胞化学显示，在七对内鳃孔之间的所有六个侧咽位置都有味蕾和相关轴突。咽部最前部比最尾部含有更多和更大的味蕾。记录到了味觉感受器细胞对甜、苦、氨基酸和胆汁酸牛胆酸以及三磷酸腺苷的反应。在所有六个有味蕾的咽部位置都观察到了类似的化学感觉反应。总之，这项研究表明，海鳗的七个咽部区域都有明显的味蕾和味觉受体细胞活动。

期刊介绍： The Journal of Comparative Physiology A welcomes original articles, short reviews, and short communications in the following fields: - Neurobiology and neuroethology - Sensory physiology and ecology - Physiological and hormonal basis of behavior - Communication, orientation, and locomotion - Functional imaging and neuroanatomy Contributions should add to our understanding of mechanisms and not be purely descriptive. The level of organization addressed may be organismic, cellular, or molecular. Colour figures are free in print and online.
