During routine educational dissection studies, we encountered multiple muscular anomalies in a 25-year-old embalmed male cadaver. The muscular anomalies were observed on the right side. In accordance with their origin, insertion and innervation features, the abnormal muscles were considered sternocleidooccipital, sternomastoid and cleidomastoid muscles. The unilateral muscle variations were observed in both the superficial and deep layer. In the superficial layer, there were two muscles and one muscle bundle, while there was only one muscle in the deep layer. The first muscle in the superficial layer, known as sternocleidooccipital muscle, consisted of clavicular head and sternal head. The second muscle in the superficial layer was sternomastoid muscle. The muscle observed in the deep layer was cleidomastoid muscle. Additionally, a muscular bundle was observed between the sternocleidooccipital and sternomastoid muscles. A combination of these variations in the same case has not, to our knowledge, been previously described in the available literature.
在常规解剖学教学研究中，我们在一具25岁的防腐男性尸体上发现了多处肌肉异常。这些肌肉异常出现在右侧。根据其起止点和神经支配特点，这些异常肌肉被认为是胸锁枕肌、胸锁乳突肌和锁骨乳突肌。单侧肌肉变异在浅层和深层均有观察到。在浅层，有两块肌肉和一束肌束，而在深层只有一块肌肉。浅层的第一块肌肉即胸锁枕肌，由锁骨头和胸骨头组成。浅层的第二块肌肉是胸锁乳突肌。深层观察到的肌肉是锁骨乳突肌。此外，在胸锁枕肌和胸锁乳突肌之间观察到一束肌束。据我们所知，同一病例中这些变异的组合在现有文献中尚未有过描述。
