前锯肌（Serratus anterior muscle），将肩胛骨内侧向前拉的胸部肌肉

每组两块的前锯肌从胸前部的肋骨开始，围绕体侧延伸到肩胛骨。 前锯肌可将肩胛骨内侧向前拉而外翻，使肩膀抬高，「锯肌」一词描述此肌成锯形的，也就是参差不齐的。

The serratus anterior (/ˌsᵻˈreɪtəs ænˈtɪəri.ər/) (Latin: serrare = to saw, referring to the shape, anterior = on the front side of the body) is a muscle that originates on the surface of the 1st to 8th ribs at the side of the chest and inserts along the entire anterior length of the medial border of the scapula.
