Thigh Muscles Behind Leg Motion

Description

Thigh muscles help move the leg through flexion, extension, adduction, and rotation. They are grouped into the anterior, medial, and posterior compartments of the thigh. Each group supports a different part of leg motion at the hip and knee.

The anterior compartment includes the quadriceps femori...

支配腿部运动的肌肉位于大腿的前侧、内侧和后侧肌室。

股四头肌是最显著的前 compartment 肌肉,由股外侧肌、股内侧肌、股中间肌和股直肌组成。其主要功能是伸展膝关节。 

缝匠肌也位于前部筋膜室中。它可屈膝,并在髋关节处引起大腿外旋,因此被称为“裁缝肌”,因其有助于盘腿而坐。

股薄肌是位于内侧肌间隔的一块带状肌肉,可使膝关节处的小腿屈曲。此外,它还能使大腿内收和内旋。 

后侧肌群引起膝关节屈曲和髋关节伸展。

后部肌群包括三条腘绳肌——股二头肌、半腱肌和半膜肌。这些肌肉的撕裂,即腘绳肌拉伤,是一种常见的运动损伤。

腘肌是一块位于膝关节后侧的小型肌肉,有助于腿部运动。它可使胫骨内旋,从而在屈曲时解锁伸展...
