胸长神经
胸长神经(nervus thoracicus longus),又称“外呼吸贝尔神经”(external respiratory nerve of Bell)[1],源自于第五至第七对颈脊神经(C5-7)的脊神经前支,主要支配前锯肌。一般来说C5和C6会穿过中斜角肌,C7则会从该肌肉前方穿过,有时C7不会加入胸长神经。

结构
胸长神经起自C5-C7神经根,在臂丛主要结构后向外下进入腋窝,沿胸侧壁前锯肌表面随胸外侧动脉下行。[2][3]
变异
在大约 10% 的人群中,胸长神经也接受来自 C8 的神经供应。[3]
临床意义
翼状肩
翼状肩是指胸长神经损伤引起前锯肌瘫痪,肩胛骨脊柱缘翘起呈翼状。[4]乳房切除术、臂丛炎可能造成胸长神经的损伤,从而导致翼状肩。[5]
