The lamina propria also contains capillaries, arterioles, and
nonmyelinated nerve fibers.
Within the olfactory nerve, the OECs form cellular channels or tunnels through which large numbers of small-caliber
nonmyelinated axons distribute through the olfactory nerve into the outer nerve layer (ONL) of the OB and extend into the olfactory glomeruli, where they make synapses (Figure 1) [19].
The vasomotor fibers are
nonmyelinated postganglionic twigs arising from the cervical sympathetic ganglia and exerting an influence on thyroid secretory activity via their action on blood vessels.[8] The adrenergic fibers supply receptors located near the follicular basement membrane.
The
nonmyelinated fibers in the RLN are sympathetic carotid plexus fibers and parasympathetic postganglionic dendrites, whose cell bodies lie in the superior jugular and plexiform ganglions.

nonmyelinated fibers in the rat peroneal nerve: a quantitative ultrastructural analysis.
