四头肌

According to Hofmann[2] et al., this approach preserves the vascularity of the patella by sparing the intramuscular articular branch of the descending genicular artery and preserves the quadriceps tendon, providing more stability to the patellofemoral joint in total knee arthroplasty.

Hofmann等人认为此法不但保留了膝降动脉的肌内关节支从而保存了髌骨的血运，而且保存了股四头肌腱从而使全膝关节置换术中髌股关节获得了更大的稳定性。

Materials and Methods 20 New-Zealand White rabbits were divided randomly into 2 groups. Complete Freund adjuvant was injected into the left dorsal footpads of 10 rabbits so as to set up ipsilateral lymphadenitis model, while the right legs were measured as normal control. The left 10 rabbits received a subcutaneous implantation of VX2 tumor cell suspension (4×10~7 cells/ml) in fight thighs.

材料与方法：20只健康新西兰白兔随机分为两组，分别经左侧足垫注射完全弗氏佐剂建立淋巴结炎性增生模型和经右侧股四头肌注射VX2癌细胞悬液(4×10~7／ml)建立肿瘤转移淋巴结模型，以炎症组的对侧下肢不作任何处理作为正常对照。

Objective To observe in vitro expression of blood coagulation factorⅧgene carried by Lentivirus by intramuscular injection.

中文摘要：目的本研究制备携带人凝血因子Ⅷ基因的重组慢病毒，并肌肉注射到正常大鼠股四头肌，观察体内的表达。

However , once you strengthen your quads , the pain will often go away .

但是，当你增强了股四头肌的力量后，这种疼痛可以消失。

People with hyperextended knees usually have weak quadriceps, or do not tend to engage them fully in straight-legged poses like Tadasana and Trikonasana.

Quadriceps flexibility is crucial for the drop-knee move so frequently required on difficult overhanging routes.

四头肌的柔软对在悬岩要常做膝盖向下的动作很重要。

The transfer of either phrenic nerve or accessory nerve to femoral nerve through the vascularized ulnar nerve bridging can improve the movement and sensation of quadriceps femoris muscle in rats, especially by the transfer of phrenic nerve.

大鼠隔神经、副神经通过桥接尺神经移位吻合至股神经，可恢复股四头肌部分功能，用膈神经转位疗效较好。
