ramus

Disease from surrounding structures can invade the masticator space via the pterygopalatine fossa, the buccal space immediately anterior to the ramus, the foramen ovale, or by way of direct invasion.

咀嚼间隙临近的病变可循翼腭窝、颊间隙、上颌窦、卵圆孔等途径侵及咀嚼间隙。

In both types of feather, the barbules that extend from the barb ramus grow from a single layer of cells, called the barbule plate, on the periphery of the barb ridge.

而不论是何种毛，从主延伸出来的，都从脊表面叫做「板」的单层细胞长出来。
