  • Look Inside

 The presence of acetylcholinesterase was demonstrated histochemically in the temporal bone of the squirrel monkey and the human nasal mucosa.

 A rich supply of cholinergic nerve fibers was observed in the intermediate portion of the facial nerve and, also, in the greater superficial petrosal nerve in the monkey.

 In the human nasal mucosa, cholinergic innervation was mostly seen around the arteries and arterioles while, very little was detected around the veins. These nerve fibers were richly distributed around the serous and mucous glands as if they were encapsulated by the latter structures and they presented intense acetylcholinesterase activity.

 However, the ducts of the gland and the epithelial layer failed to show any cholinesterase activity.

 The author concluded that these cholinesterase-positive nerve fibers are derived from the pre- and postganglionic parasympathetic nerves which supply the nasal mucous membrane and possibly play the chief role causing nasal congestion and rhinorrhea of the vasomotor rhinitis.
