21. In addition, they contain sympathetic fibers from the superior cervical ganglion to the dilator pupill?muscle. 22. From this is attached the back of the dilator naris and ends below in a pointed process. 23. As such, it also relaxes the iris dilator muscle by binding to its postsynaptic nerve endings. 24. The authors describe an alimentary canal with terminal openings and a rectum with what might be dilator muscles. 25. These fibres then distribute to deep structures, which include the Superior Tarsal Muscle and pupillary dilator muscles. 26. The affected pupil is thus miotic and the pupillary dilator responds to denervation by increasing ? 1 receptors. 27. The dilators were invented to relieve nasal stuffiness and make breathing easier for people with deviated septums and allergies. 28. And it is thought that these vessel dilators work in clitoral tissue just as they do in penile tissue. 29. They will also pass through ciliary ganglion and travel in short ciliary nerves to reach the iris dilator muscle. 30. The use of the sympathomimetic drug causes the iris dilator muscle to be directly stimulated, causing increased dilation.
