title: Ophthalmic terminals in the iris and the ciliary body of monkeys. An electron microscopical study.
abstract: Recent studies have indicated that sensory terminals can be recognized by the presence of an accumulation of mitochondria. By inducing changes in uveal ophthalmic nerve fibers it was shown that an accumulation of mitochondria also occurs in autonomic terminals. Although an aggregation of mitochondria may occur in sensory terminals, it is not a feature unique to them. The ophthalmic fibers in the iris and the ciliary body appeared to terminate as free nerve endings without characteristics peculiar to them.
