Summary
Unusually large nerve processes, containing numerous mitochondria, glycogen particles, and synaptic vesicles are described in both the ciliary muscle and the iris sphincter muscle of the rhesus monkey. The striking similarity of these axonal profiles to the dendritic enlargements observed by Sotelo and Palay (1968) is noted and the possibility that they represent growing ends of peripheral nerve fibers is suggested.
