Description

The ciliary ganglion of the guinea pig was studied by fluorescence and electron microscopy.<br>The fine structure of the perikaryon of the ganglion cells is similar to that previously described for sympathetic ganglion cells in various species of mammals.<br>Every presynaptic nerve ending in the ciliary ganglion contains numerous agranular vesicles mixed with a few large granular vesicles, thus corresponding to the type which has been generally considered to be cholinergic. Adrenergic nerve endings and catecholamine containing cells could not be found in the present study. No adrenergic nerve elements could be recognized even after the administration of nialamide or nialamide plus L-dopa.<br>These findings indicate that the ciliary ganglion cells of the guinea pig are innervated purely by cholinergic nerves. Adrenergic nerve elements do not seem to be involved in the synaptic transmission.<br>The spinous protrusions emerging from the postsynaptic element do not intrude into the swollen nerve endings but only cover their surface.
