title: Large granular vesicles in the frog spinal cord.
abstract: Two types of large granular vesicles have been demonstrated in the spinal cord of the frog Rana esculenta. Each type is contained in different fibres located in the neuropil of the ventral horn. The two types of vesicles differ in their diameter and quantity, in the smoothness of their limiting membrane and the electron density of their core. The possibility that they contain peptides is discussed.
