二腹肌

The greatest diameter of Glossopharyngeal Nerve was 1 .2 mm .

二腹肌后腹亦可作为术中辨认舌咽神经的解剖标志。

二腹肌下颚的一个肌肉，可提升舌骨和协助降低颚那位拳击手看准了机会，猛击对手的下颚。

On this projective line is the good position for cuting the sternoeleidomastoid muscle and accesory nerve.

二腹肌后腹深面为高位结扎切断副神经点，若再向上易伤颈内静脉。

Methods The anatomical structures correlative with submental artery,submental vein,anteroventral portion of digastric muscle and mandibular periosteum in 23(46 sides)cephalocervical samples were measured.

结果 颏下动脉为面动脉的恒定分支，走行于下颌下腺与下颌骨下缘之间，恒定分支供应二腹肌前腹和下颌骨骨膜，并与对侧有广泛的吻合支。

The in vitro effects of Gln49-PLA_2 were examined using the chick biventer cervicis nerve muscle preparation. Gln49-PLA_2 caused a dosedependent blockade of neuromuscular transmission. The time required to cause 50% blockade was about 150 min at the highest concentration 100μg/ml. This inhibition appeared to be presynaptic in origin as evidenced by the lack of effect of toxin on responses to exogenous acetylcholine in the non-stimulated BCp.

Gln49-PLA_2能够剂量依赖性地抑制颈二腹肌神经信号正常传导并影响肌肉收缩，在100μg/ml剂量下，肌肉收缩幅度在150分钟后达到50%的抑制率；同时，随着Gln49-PLA_2浓度的降低，肌肉收缩幅度的抑制效率也逐渐降低；实验证明Gln49-PLA_2对突触后膜乙酰胆碱受体敏感性无影响，对神经肌肉信号传导收缩的抑制作用位点在突触前膜。

The important and perpetual anatomic landmarks looking for facial nerve in the course of operation are horizontal semicircular canal,digastric ridge,facial recess,cochleariform process,tarin foramen, arcuate eminence and foramen spinosum.

经乳突联合颅中窝径路行面神经手术时，二腹肌嵴、外半规管凸、砧骨短突、面神经隐窝、匙突、弓状隆起、棘孔、面神经管裂孔为该手术径路中寻找面神经的恒定的、重要的解剖标志。

Glossopharyngeal Nerve crosses the deep surface of the stylopharyngeus muscle 23 to 47 mm cephalic to the bifurcation of the carotid artery and 7 to 15 mm from the tip of the styloid process .

在颗下窝区，茎突根部、鼓板下缘、寰椎横突、乳突尖以及下领角等可作为舌咽神经颅外部分的参考标志。3在乳突尖到下领角轴线区，切除二腹肌后腹时应注意区别和保护舌咽神经。

After the functional appliance protruded the mandible, it resulted in a clear alteration in the biomechanical characteristics of the masticatory muscles. The contractile tension of lateral pterygoiod muscles incerased with its contraction time prolonges, while that of the digsstic muscle decreased and shortened.

当功能性矫治器引导下颌前伸后，对运动下颌肌肉作在体等长主动收缩性质的检测，结果表明翼外肌收缩张力增强，收缩速度变慢；二腹肌前腹收缩张力减弱，收缩速度加快。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
