Abstract

The omohyoid is a digastric muscle that crosses the neck from the superior border of the scapula to the body of the hyoid bone. Variations in the omohyoid muscle are common, but a double omohyoid is considered rare and may have important clinical implications. The anatomical dissection of the neck of a middle-aged male cadaver revealed an abnormal three-headed duplicated omohyoid muscle. Behind the clavicle, the intermediate head bifurcated and fused with the medial and lateral heads, forming a small plexus that gave rise to two separate bellies, one lateral, and one medial. The bellies ascended in a superomedial direction before inserting into the hyoid bone next to each other. The intermediate tendon was rudimentary in the lateral belly and absent in the medial one. The anatomical variation described here has not been previously reported and may have clinical significance.

人类尸体上的三头复制肩胛舌骨肌。
肩胛舌骨肌是横跨颈部的二腹肌从肩胛骨上缘到舌骨体。肩胛舌骨肌的变异是常见的,但双肩胛舌骨肌被认为是罕见的,可能具有重要的临床意义。对一名中年男性尸体的颈部解剖发现异常的三头复制肩胛舌骨肌。在锁骨后面,中间头分叉并与内侧头和外侧头融合,形成一个小神经丛,产生两个独立的腹部,一个外侧,一个内侧。在插入舌骨之前,腹部在一个上内侧方向上升。外侧腹部的中间腱发育不全,内侧腹部的中间腱缺失。这里描述的解剖变异以前没有报道过,可能具有临床意义。
