环椎 meaning in Chinese
atlas
lepospondylous
Examples
- Atlanto occipital joint
环椎枕颗关节 - Our study showed the following : mastoid process , transverse process of the atlas , and occipital condyle were important signs , superior and inferior suboccipital triangle is the important mark for distinguishing vertebral artery
研究显示：乳突、环椎横突和枕髁是术中重要的解剖学标志，上、下枕下三角是暴露椎动脉入颅前的一个重要解剖学标志。 - Measurements for the following anatomical structures were obtained with the aid of a microscope , the distance between mastoid process and transverse process of the atlas , occipital condyle , and superior lateral loop ; the distances between the midline and the v3 at three levels : 1 ) the distal ( dural ) ring ; 2 ) the intersection with the anterior ramus of the c - 2 ; and 3 ) the upper level of the transverse foramen of the atlas ; the diameter of v3h at the origin of the muscular artery and at the sites of penetrating the dural ring ; the width of the v3 at the intersection with the anterior ramus of the c - 2 and at the sites of penetrating the transverse foramen of the atlas
V _ 3h和v _ 3v各有两个分支： v _ 3h分出肌动脉支和脑膜后动脉支； v _ 3v分出肌动脉支和根肌动脉支，第一、二脊神经发出的前后支分别与它们又毗邻关系。通过手术显微镜测量下述解剖结构：乳突尖与环椎横突尖、枕髁外侧缘、 v _ 3上外侧袢的距离；椎动脉v _ 3段在穿硬膜环、与第二颈神经前支交叉、环椎横突孔上缘三处与中线的距离； v _ 3h在发出肌支处和穿硬膜天浑医科大学硕士研究主学位论文环处的直径； v3v在与第二颈神经前支交叉处和穿环椎横突孔处的直径。
