在局部解剖学实习中,发现一成年男尸左侧斜方肌部分缺如及肩胛骨变异,未见有其他外伤疤痕.1左侧斜方肌上部肌肉起止点均正常,唯有下部肌缺如,仅残留有一微薄三角形结缔组织膜.该膜由正中线至肩胛冈内侧端为51mm,在正中线上,由上(肩胛冈内侧端平面)向下为107mm.翻开该膜,可见菱形肌,小菱形肌缺如,大菱形肌较小,起自第2～4胸椎棘突,止于肩胛骨内侧缘中1/3.翻开左斜方肌上部肌肉,可见一独立小肌肉,起止于第7颈椎棘突与肩胛骨内侧角稍下方,长70mm,宽
In the local anatomy internship, we found an adult male left part of the trapezius muscle absence and scapular variation, there are no other traumatic scars.1 The left trapezius muscle above the starting and ending points were normal, only the absence of the lower part of the muscle , Leaving only a thin triangular connective tissue membrane.The membrane from the midline to the scapular the medial end of 51mm, in the midline, from the (scapular the medial side of the plane) down to 107mm. Open the membrane, the diamond can be seen , A small diamond-shaped muscle absence, large diamond-shaped muscle smaller, from the first 2 ~ 4 thoracic spinous process, ending in the medial margin of the scapula 1. Open the left trapezius upper muscle, showing an independent small muscle, starting and ending in 7th cervical spine and scapular medial corner slightly below, 70mm long, wide
