體側線

體側線（lateral line；lateral line system (LLS)；lateral line organ (LLO)；側線管系；側線系；側線系統）是壓力感受器官，又稱側線或感覺溝，俗稱魚腥線。幾乎所有的魚、在水中生活的兩棲動物如蠑螈或是爪蟾，還有很多水生的爬行動物，如鱷魚等，都有體側線。這種細小的感受器官成百上千的排列在身體側邊。在魚類身體側面大於正中，人們可以看見一條清晰的點狀線，故名。體側線感受水流和壓力波。^[1]

體側線的組成有兩種，一是勞倫氏壺腹（Ampullae of Lorenzini），二是神經丘（Neuromasts）。後者是眾多的感受細胞，它們的感覺毛在膠質狀的壺腹帽（Cupula）中。水流造成壺腹帽的偏移，產生神經衝動。
