枕骨

The blood supply of cerebrum （60%） is mainly provided by the middle and rostral cerebral arteries which arise from the internal carotid.

上述血管的分支于大脑垂体周围和枕骨基底部分别形成前、后硬膜外异网和大脑动脉环。

The brain lies underneath the sinciput; the occiput is hollow.

脑位于前顶下面；枕骨是空的。

The results indicate that both have well-developed nasals, frontal, opisthotic, and squamosal bones, but they have no orbitosphenoid, basisphenoid, pseudomesia bar, or supplemental maxilla.

研究结果表明：2种鱼均有发达的鼻骨、额骨、后耳骨和鳞片骨，上颌口缘由前颌骨构成，犁骨上具齿，上枕骨与额骨相接，左右顶骨分离，无眶蝶骨、基蝶骨、伪头中骨和辅上颌骨。

We now present a case of a patient who underwent a suboccipital craniotomy for resection of a cerebellar pontine angle meningioma.

现在我们这里有这样一个患者，这个患者从枕骨下开颅行小脑脑桥角脊膜瘤切除术。

METHODS: Six patients aged 18 years or older who were diagnosed with HC had a suboccipital bion device implanted ipsilateral to their headache and received continuous unilateral ONS.

6例18岁及以上诊断为HC患者，在其头痛部位同侧的枕骨下植入生物体装置，接受持续的单侧ONS。

MRI detected typical post-operative changes due to a previous suboccipital craniectomy, of marked and diffusely thickened dura.

MRI除了以上几幅图所示的改变，还可见因之前枕骨下颅骨切除术而造成的典型的术后改变，在这里没有给出。

Thirty patients who had CM-I associated with syringomyelia and who underwent FMD participated in the study.

30名CM－1型伴脊髓空洞型以及行枕骨大孔减压术的患者参与了研究。

The occipital boneisvery prominent. The head is surmountedby a topknot of long silky hair.

后枕骨非常突出，头顶的"头发"是丝状的、长长的毛发。

The results were compared with control group. Results In group of ill pregnanted fetus, the contents of necessary nutrition elements in blood and tissue were all lower except that Fe in the group of congenital malformed foetus was high. The variation was especially evident in gravida's biood, umbilic blood, placenta, and liver of fetus. The contents of heavy metals such as Pb, Cd, Hg were all higher, and the variation was evident in placenta, liver of fetus and occipital bone.

结果 除先天性畸形胎儿组中的铁偏高外，其余血液及各组织中必需营养元素钙、锌、铜、铁、硒和维生素A含量普遍偏低，在母血、脐血和胎盘及胎儿肝脏中差异显著(P.05)；重金属铅、镉、汞含量普遍较高，在胎盘、胎儿肝脏和枕骨等组织中差异显著(P.05)。

Methods The contents of many kinds of elements such as Ca, Zn, Cu, Fe, Se, Pb, Cd, Hg were respectively detected in cerebra, gluteu, thymus, occipital bone, liverof congenital malformed and inevitable abortion foetus at the age of five to eight months and correlative gravida's blood, umbilic blood, placenta, and the contents of vitamin A from gravida's blood and umbilic blood.

分析5~8个月龄先天性畸形胎儿和难免流产胎儿大脑、臀肌、胸腺、枕骨、肝脏组织及与其相关的母亲血、脐血、胎盘中钙、锌、铜、铁、硒、铅、镉、汞以及其母亲血、脐血中维生素A的含量，并与正常对照组比较。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
