生命的第一周受精卵经过多次分裂，形成一个细胞团
第二周脊椎形成了，脑组织、脊髓及神经系统，还有眼睛，都具有一定的雏形
胎儿的脑部组织也就开始形成了
第四周时出现心脏，又过1周出现肢体萌芽，眼睛、耳朵随着出现，肺、肝也开始出现雏形
胚胎至第七周时，手足开始出现手指、足趾，眼睛清晰可见，胚胎开始伸直并在羊水中活动，整个外观近似幼儿，尾巴消失。
l在怀孕第8周时，神经管便渐次愈合， l第八周初：胎儿的头占整个身体的l/2，以后生长加快， l开始被称为胎儿。胚胎已近3厘米，所有的器官已初具原形。以后的几个月就只待逐渐完善了。
l第九周时，男女胎儿外阴大致相似。第十二周末，已显示成熟胎儿男女外阴的形态 l第四个月(12—15周)，胎儿身长为16厘米，体重大约120克，生长非常迅速。 l第五个月(16—19周)，孕妇就会感觉腹内胎儿在踢自己以显示他的存在，这就是胎动。 l胎儿已具备听力，能听见声音，可开始进行胎教了。第六个月(20—23周)，两条胳膊弯曲在胸前，两只膝盖提到腹部。第七个月(24—27周)，看起来像个小老头儿。这时出生虽能有浅表的呼吸和哭泣，但仍很难存活。 l第八个月(28—31周)，神经系统进一步完善，肺及其它内脏已发育完成。 •第九个月(32—35周末)，发育基本完成。。 •第十个月(36—40周)，胎儿发育完成，一个新生命诞生啦
