摘要
目的 为研究个体发育年龄解剖学提供资料.方法 从胎儿背侧打开椎管,暴露脊髓,观察50例胎儿的脊髓节段与脊柱的位置关系.结果 各被观察脊髓节段下界的平均位置是:第4颈节平对第3颈椎(C_3);第8颈节平对第6~7颈椎间盘;第4胸节平对第3胸椎(T_3);第8胸节平对第7胸椎;第12胸节于对第10胸椎;第5腰节平对第12胸椎至第1腰椎间盘;脊髓末端在第2腰椎水平.结论 从胎儿到成人,脊髓下端的位置随着年龄的增长而逐渐上升.
Objective To provide information for the study of individual development and age anatomy. Method Through cutting the vetebral canal open from the dorsum and exposing spinal cord, the relationship between spinal segment and vertebral column position of 50 cases of normal induced labor fetus.Results The mean portion of each inferior bound of spinal segment examined is the 4th and the 8th neck segments are on the same level with C_3 and C_6-7 intervertebral disc respectively;the 4th and the 8th chest segments are on the same level with T_3 and T_7 respectively; the 12th chest segment is on the same level with T10 and the 5th lumbar segment is on the same level with T_(12)-L_1 intervertebral dise; the end of spinal cord levels with L_2 And the positions of cervical enlargement and lumbosacral enlargement are describedl. Conclusion The position of the lower part of the spinal cord goes up gradually as one grows older from fetus to adult ehood.
