本文用9例孕16、18、21、23、27、32、33、35和40周胎儿、1例2月龄婴儿、1例16岁青少年和1例63岁成人的脑连续切片研究了人舌下神经核的发育。形态测量分析得出了以下三个与人类舌下神经核发育有关的结果：（1）妊娠32周后发育可能加速;（2）出生后可观察到成熟;（3）胎儿发育期间可能发生自然细胞死亡，如神经元数量减少和退化神经元的出现所示。
Development of the human hypoglossal nucleus was studied using complete serial sections of the brains of 9 fetuses at 16, 18, 21, 23, 27, 32, 33, 35 and 40 weeks of gestation, a 2-month-old infant, a 16-year-old adolescent and a 63-year-old adult. Morphometric analysis produced the following three findings pertaining to the development of the human hypoglossal nucleus: (1) development may accelerate after 32 weeks of gestation; (2) postnatal maturation is observable, and (3) natural cell death, as indicated by a decrease in the number of neurons and the appearance of degenerating neurons, may occur during fetal development.
