应该叫声带啦
the vocal cords; vocal folds
The vocal cords, also known as vocal folds, are composed of twin infoldings of mucous membrane stretched horizontally across the human larynx. They vibrate, modulating the flow of air being expelled from the lungs during phonation.
声带又称声壁,发声器官的主要组成部分。位于喉腔中部,由声带肌、声带韧带和粘膜三部分组成,左右对称。声带的固有膜是致密结缔组织,在皱襞的边缘有强韧的弹性纤维和横纹肌,弹性大。两声带间的矢状裂隙为声门裂。发声时,两侧声带拉紧、声门裂缩小、甚至关闭,从气管和肺冲出的气流不断冲击声带,引起振动而发声,在喉内肌肉协调作用的支配下,使声门裂受到有规律性的控制。故声带的长短、松紧和声门裂的大小,均能影响声调高低。成年男子声带长而宽,女子声带短而狭,所以女子比男子声调高。青少年14岁开始变音,一般要持续半年左右。
