在七鳃鳗脊髓白质的外侧边缘，有一群神经细胞被称为边缘细胞。生理、光镜和EM联合研究的结果表明，这些细胞是椎管内的机械感受器。边缘细胞在脊髓外侧缘的伸展处去极化，它们在该区域具有定向为吻尾平面的巢状分支。这些细胞在结构上与小龙虾的伸展感受器非常相似。
In the lateral edge of the white matter in the lamprey spinal cord, there is a group of nerve cells referred to as edge cells. The results of a combined physiological, light microscopical and EM study suggest that these cells serve as intraspinal mechanoreceptors. Edge cells are depolarized on stretch of the lateral margin of the spinal cord, and they have nestlike ramifications in this region oriented in a rostrocaudal plane. These cells exhibit a close structural similarity with the crayfish stretch receptor.
