The Muscular System

Leg Muscle Groups for Foot Motion

Description

The leg muscles that move the foot and toes are organized into the anterior, lateral, and posterior compartments. Each compartment has a distinct set of muscles with its own actions. Together, they control dorsiflexion, plantar flexion, inversion, eversion, and toe movement.

小腿中负责移动足部和脚趾的肌肉可分为前部、外侧和后部三个筋膜室。

前骨筋膜室包括胫骨前肌、拇长伸肌、趾长伸肌和第三腓骨肌。

这些肌肉可使足背屈。胫骨前肌使足内翻,而腓骨第三肌使足外翻。此外,长伸肌和趾长伸肌分别伸展大脚趾和其他脚趾。

外侧骨筋膜鞘包含腓骨长肌和腓骨短肌,二者可使足跖屈并外翻。

后 compartment 肌肉分为浅层和深层。

后侧浅层包含腓肠肌和比目鱼肌,可实现足部跖屈。腓肠肌还可屈曲小腿。跖肌是一块较小的肌肉,可能成对存在,参与足部跖屈。

后侧深层肌肉使足跖屈,但腘肌除外,后者使胫骨内旋。

此外,拇长屈肌和趾长屈肌分别屈曲大脚趾和其他脚趾。胫骨后肌使足部内翻。
