Abstract

<p>In the visual organs, parasympathetic innervation causes pupillary constriction, ciliary muscle constriction, increased choroidal blood flow, and lacrimal secretion. These responses are mediated by acetylcholine (ACh) M3 receptors, nitric oxide (NO), and vasoactive intestinal peptide (VIP). Sympathetic innervation causes pupillary dilation, decreased choroidal blood flow, and mild tear secretion via alpha receptors. In the olfactory organs, parasympathetic innervation promotes mucus secretion and increases mucosal blood flow. Sympathetic innervation is involved in decreasing mucosal blood flow. In olfactory cells, both parasympathetic and sympathetic nerves have been suggested to enhance odor responses. The odor-induced increased blood flow in the olfactory bulb is enhanced by activation of α4β2 nicotinic ACh receptors.</p>
