鯊魚的體側線

体侧线(lateral line;lateral line system (LLS);lateral line organ (LLO);側線管系;側線系;側線系統)是压力感受器官,又稱侧线感覺溝,俗称鱼腥线。几乎所有的、在水中生活的两栖动物蝾螈或是爪蟾,还有很多水生爬行动物,如鳄鱼等,都有体侧线。这种细小的感受器官成百上千的排列在身体侧边。在鱼类身体侧面大于正中,人们可以看见一条清晰的点状线,故名。体侧线感受水流和压力波。[1]

体侧线的组成有两种,一是劳伦氏壶腹(Ampullae of Lorenzini),二是神经丘(Neuromasts)。后者是众多的感受细胞,它们的感觉毛在胶质状的壶腹帽(Cupula)中。水流造成壶腹帽的偏移,产生神经冲动。
