伸肌

This involves minimal dissection in the interval between the extensor carpi radialis brevis and extensor digitorum communis distally as described by Kaplan.24 The distal extent of the incision is limited so as to provide exposure of the capitellum without violating the annular ligament or the posterior interosseus nerve.

Also no significance was found in flexor and extensor between left side and right side in women.

在速度为240/s时，男子左屈肌达到峰值力矩的关节角度大于右屈肌，而左伸肌和右伸肌差异不存在显著性。

The unoperated sides of the treated animals also served as controls. Six normal rats were treated as normal control group. Three different siRNA plasmid solution containing RC2-Ⅰ, MAFbx-Ⅱ, CON (50μl , 0.8μg/μl)was injected and transfected by electroporation as methods mentioned above, respectively. The changes of RC2 and MAFbx mRNA levels and RC2 protein levels after 3 days were determined by real-time quantitative PCR and Western blot, respectively. On postoperative 2, 3 and 4 weeks, the rate of wet muscle weight preservation, mean diameter of muscle fiber and mean cross-section area of muscle fiber and muscle protein content were checked and then compared between group CON and group RC2 or group MAFbx, respectively. The differences between groups were analyzed by one-way ANOVA. Ultrastructural changes of muscle fiber were observed at 2, 3, 4 weeks postoperation.Results GFP plasmid was efficiently deliverd into muscle by electroporation and robust GFP expression in muscle could be observed more than three weeks. Histology shows that injected plasmid DNA diffuses extensively in muscle tissue.

To observe and measure the distance and angulation of some muscles such as flexor carpi ulnaris,extensor carpi ulnaris , flexor carpi radialis,extensor carpi radialis longus,extensor carpi radialis brevis, brachioradialis,etc,we achieved the moment of force and loaded them in the model .

测量8具新鲜成人尸体的前臂主要肌肉和韧带横截面积，分别取其平均值，通过横截面积的肌力计算法，求得肌力和韧带力。主要肌肉为肱桡肌、桡侧腕长伸肌、桡侧腕短伸肌、尺侧腕伸肌、尺侧腕屈肌、桡侧腕屈肌等。测量的主要韧带为腕掌侧韧带、腕背侧韧带等。测量主要肌肉和韧带与坐标轴的夹角，求得分力值，然后直接或根据力矩等价原则间接地将肌力加载于模型体表各节点。

The lateral tendinous fascicle formed mainly functional anatomic mechanism of the proxinmal interphalangeal joint was extended, and it had close relation to the lateral fascicle and had a coordinated action with the lateral tendon.The lateral tendinous fascicle had also association with the flexor tendinous sheath, and made the flexor tendinous sheath play a role in balancing muscular strength of flexor and extensor.

外侧腱束主要形成伸近节指间关节的功能解剖机制；其与外侧束形成的密切纤维联系而具有协同外侧腱的功能；该腱束与屈肌腱鞘有联系又使其具有平衡屈肌和伸肌肌力的作用。
