The linear marking method was employed to study morphogenetic movements of tissues involved in the development of the definitive position and shaping of the shoulder and arm. Chick embryos in the range of embryonal day 3.5 to 4.5 were used with the following results: -Asymmetrical growth of the early wing bud and the oblique position of humerus anlage in the early wing bud as proposed by Saunders (1948) and Seichert (1965) were confirmed. -It was found that the cranial ascend of the shoulder (Seichert and Knospe 1992) is accompanied by the slight ventromedial rotation of the complex consisting of the scapula and coracoid. -Torsion along the longitudinal axis of the stylopodium was observed: the proximal part of the stylopodium (both the humerus anlage and related soft tissues) moves in the sense of supination, the distal part moves in the sense of pronation.
采用线性标记法研究参与肩部和手臂最终位置发育及塑形的组织的形态发生运动。使用胚胎第3.5至4.5天范围内的鸡胚，结果如下：- 证实了桑德斯（1948年）和赛希特（1965年）提出的早期翅芽不对称生长以及早期翅芽中肱骨原基的倾斜位置。- 发现肩部的头侧上升（赛希特和克诺斯佩，1992年）伴随着由肩胛骨和喙突组成的复合体的轻微腹内侧旋转。- 观察到沿 Stylopodium 纵轴的扭转：Stylopodium 的近端部分（肱骨原基和相关软组织）以旋前的方向移动，远端部分以旋后的方向移动。
