内耳側線系感覚上皮の微細構造

The fine structure of the sensory epithelium in the acoustico-lateralis system

　各種脊椎動物の聴覚器，前庭器，側線器などはそれぞれ音，重力，加速度および外液の振動あるいは移動の受容器として生理的に異なった機能を持っているが，蓋膜，耳石あるいはクプラなどと感覚細胞先端部にある感覚毛との相対的な位置の移動を感知するという共通の感覚受容機構に従っており，それらの感覚上皮は基本的にはすべて共通の構造を持っている。

Abstract

The lateral line organs and the acoustic and vestibular sensory organs in the inner ear are generally called an acoustico-lateralis system. They have different physiological functions asbeing receptors for disturbance of the external fluid, sound, gravity and acceleration, however, they have basically the similar structure. The sensory cells of these organs have the sensory hairs on their apical surface. The principle of their detector mechanisms is the same, the detec-tion of the displacement of the sensory hairs.
