1. The protuberances on the center of echinocytes are lodged and embedded. 中央棘刺状突起并非伸向细胞片面外，而是倒伏包埋在细胞中。

3. Also, the scoops swivel out of the way if they encounter anything solid, so the dredge does not destroy such protuberances. 同时，如果半球铲子遇到任何坚实的固体，会旋转起来而不至于撞坏海底岩石等隆起物。
4. Objective To evaluate the value of endoscopic ultrasonography in the diagnoses and treatment of protuberances in upper gastrointestinal tract. 目的评估超声内镜在上消化道隆起性病变诊断及治疗中的价值。
5. Erythrocytes of the animals are elliptical and thin. Theiredge seems to be smooth, but there are some small protuberances on the cytoplasmic membrane of the cells. 这些动物的红细胞呈椭圆形，很薄，其边缘看来光滑，但在胞浆膜上有些小突起。
