Глазки Гессе

Глазки Гессе — светочувствительные органы ланцетника. Они расположены по бокам невроцеля по ходу нервной трубки. Каждый глазок Гессе представляет собой светочувствительную клетку, которая как бы погружена в чашеобразную пигментную клетку. Они способны улавливать только направление и интенсивность света.Располагаются на внутренней поверхности желобка нервной трубки[1]. Эти глазки похожи на примитивные глазки некоторых свободноживущих плоских червей. Описаны немецким зоологом Рихардом Гессе (R. Hesse)[2].
