イソアワモチ背眼視細胞の微細構造

概要

論文の詳細を見る
The retina of the dorsal eye consists essentially of a single visual cell layer with nervous process. In each visual cell the proximal and distal segments seem to be distinguishable. A distal segment corresponding to the outer segment of the rod contains several laminar cores (ellipsoidal or spherical in shape). Each laminar core has a granule-rich body at the center and joins to the cytoplasm of the proximal segment through a connecting piece. A cilium-like structure consisting of nine peripheral double tubules runs through a connecting piece. The proximal segment contains numerous mitochondria, a paranucleus and a nucleus. The important fact is that these structures are fundamental for the photoreceptors not only in vertebrates but also in molluscs.
