颊窝毒蛇的毒牙是长的空心管子。
响尾蛇位于鼻子上的中空骨腔被称为颊窝器官，内含热敏感的极度薄膜，是与大脑相连的刺激感受器。
The diamondback rattler has hollow, bony cavities above the nose called pit organs containing ultra-thin, heat-sensing membranes that activate receptors connected to the brain.
虽然这个发现的一些方面与已知的行为学和生理学工作相悖，分子基因技术的应用是了解颊窝如何工作的进步。
Although aspects of the findings contradict known behavioural and physiological work, the use of molecular genetic techniques is a new step in understanding how the facial pits work.
温暖的泪滴跌落下我的颊，唯一的温暖到在我周围的无穷尽的凹窝中被发现。
Warm tears fell down my cheeks, the only warmth to be found in the unending hollowness that was around me.
结果：得到28颗人工牙的颊舌径、近远中径、牙尖高度、中央窝深度、牙尖平衡斜面斜度的数据。
Results: The geometric feature parameters of 28 artificial teeth in their own coordinates were obtained, including the mesiodistal and buccolingual dimension, the height and inclination of cusp.
