Human physiology : designed for colleges and the higher classes in schools and for general reading . 250 HUMAN PHYSIOLOGY. Vocal ligaments. Mode of their Diagram showing the action of theVOCAL LIGAMENTS. FIG. 138. in Fig. 137 a diagram showing the arrangement of these liga-ments.

Tothese you see are attached two sheetsof membrane, which are also fastenedall around to the inside of the thy-roid. If these movable parts, as wemay call them, to which the ligamentsare thus attached, be drawn back-ward, it is obvious that it will makethe ligaments more tense. If theyare separated from each other, theopening between the ligaments willbe widened. If they are broughtnearer together, this opening will benarrowed, and the forward part of the free edge of each liga-ment will be prevented from vibrating, because it is here broughtin contact with the other there are small muscles whichare attached to the arytenoid car-tilages for the purpose of movingthem as I have pointed out.
