四头肌

Compression of nerve roots often produces objective sensory changes early, with paresthesia and loss of sensating detectable in the affected dermatome.

神经根受压常很早即产生客观的感觉变化，在受影响的皮节区有感觉异常及感觉缺失，神经根持续受压，可发生运动肌无力，若累及腰4神根，可见膝腱反射减弱和轻度股四头肌无力，小腿肌肉感觉减退。

Compre ion of nerve roots often produces objective se ory changes early, with paresthesia and lo of se ating detectable in the affected dermatome. With continued root compre ion. Motor weakne may develop. With involvement of the L4 root, the patellar tendon reflex may be diminished and slight quadrice weakne may be o erved.

神经根受压常很早即产生客观的感觉变化，在受影响的皮节区有感觉异常及感觉缺失，神经根持续受压，可发生运动肌无力，若累及腰4神根，可见膝腱反射减弱和轻度股四头肌无力，小腿肌肉感觉减退。

Electrocorticogram was recorded with silver electrodes positioned through the burr holes on both sides, and at same time, myoelectricity activity induced by clonic jerks of the extremities was recorded with the electrode inserted into the quadriceps femoris muscle of the left posterior limb.

同时在左右两侧钻开的颅骨里放置银制电极，记录皮质脑电图；在大鼠左后肢股四头肌插入肌电记录电极，记录肢体抽搐引起的肌电活动。

Therefore, your choice of exercise should make use of your largest muscles, which are your gluteus maximus and your quadriceps… your butt and your thighs.

因此，您所选择的工作应该利用你的最大的肌肉，这是您和您的臀大肌股四头肌。。。你和你的大腿对接。

The quadriceps and gluteus maximus have the highest concentration of striated muscle fibers, a pure measure of strength.

如果进行纯粹的力量测试，四头肌和臀大肌则是人体中横纹肌纤维密度最高的地区。

Can simultaneously exercise the quadriceps muscles, legs pit and gluteus.

可以同时锻炼到四头肌，腿窝和臀肌。

Under the presupposition of no evident of muscle atrophy through maximal electrical twitch, quantitative electromyographical test of patellar reflex could discover the quadriceps AMI in patients with knee OA,which was known to be the inhibition of anterior horn motoneuron.

小结：在电刺激表明肌萎缩不明显的前提下，定量腱反射的肌电图检查显示膝OA的股四头肌有明显的AMI，此关节源性肌肉抑制为脊髓前角运动神经元的抑制。

The muscles tested are bilateral biceps brachialis and quadriceps femoris muscles.

以两侧肢体肱二头肌及股四头肌为测试部位。

RESULTS: There were three functions of hamstring in gait cycle: decelerating the concentric contraction of the iliopsoas at bending hipbone; decelerating the concentric contraction of the quadriceps at knee bending; as well as making the lower limbs under the knee get certain angular momentum at toe-off, by eccentric contraction.

结果：腘绳肌在跑步周期中的作用有3个：在屈髋时通过离心收缩拮抗髂肌；在伸膝时通过离心收缩拮抗股四头肌；在支撑阶段通过向心收缩为膝关节提供动态稳固作用和使小腿和足获得一定的角动量。

Quantitative patella tendon reflex was tested electromyo-graphi cally and maximal volitional contraction of quadriceps were done on 22 unilateral knee of patients with osteoarthritis. The decreased extent of amplitude of maximal volitional contraction and patella tendon reflex were compared.

对22位单侧膝关节骨关节炎患者进行股四头肌最大等长收缩和定量髌腱反射的肌电图测试，比较患膝上两者肌电波幅的减低程度。
