Scatter charts and line charts look very similar, especially when a scatter chart is displayed with connecting lines. However, there is a big difference in the way each of these chart types plots data along the horizontal axis (which is also known as the x-axis) and the vertical axis (which is also known as the y-axis).
From Wikipedia, the free encyclopedia. A buccal exostosis (also termed alveolar exostosis), is an exostosis (bone prominence) on the buccal surface (cheek side) of the alveolar ridge of the maxilla or mandible. Some consider them a variation of normal anatomy rather than a disease.rom Wikipedia, the free encyclopedia.

Labial commissure of mouth. The commissure is the corner of the mouth, where the vermillion border of the superior labium (upper lip) meets that of the inferior labium (lower lip). The commissure is important in facial appearance, particularly during function such as smiling. As such it is of interest to dental surgeons. Diseases that involve the commissure include angular chelitis.
