The parasympathetic component of the ANS innervates the sphincter pupillae muscle of the iris. The preganglionic parasympathetic fibers controlling the sphincter pupillae originate from neurons in the Edinger–Westphal (EW) nucleus, the autonomic subdivision of the third cranial nerve nucleus, and ...

This bundle formation is accompanied by acquisition of a nerve supply from the iridial stroma, and the emergence of collagen fibers as well as secondary basal (or external) laminae surrounding each cell of the bundle. The adult muscle cells retain numerous round pigment granules, desmosomes, and...

Capsaicin-induced contraction of the isolated iris sphincter muscle, previously shown to be dependent upon an intact and functional sensory nerve supply, was not suppressed by atropine (3 × 10 −7 m) or by tetrodotoxin (10 −6 m). Capsaicin therefore, although acting via sensory nerves, ...
