胎儿发育特征
描述胎儿发育的特征,以4周为一孕龄单位。在受精后6周(即妊娠8周)称为胚胎,是重要器官分化发育时期,从受精后第7周(即妊娠第9周)起,称为胎儿。是其各器官进一步发育成熟时期。胎儿发育特征如下:4周末:可辨认胚盘和体蒂。8周末:胚胎初具人形,头大占整个胎体的一半。能分辨出眼、耳、鼻、口,四肢已具雏形。12周末:胎儿身长约9cm,体重约20g,外生殖器已发生,部分可辨出性别。肠管已有蠕动。16周末:胎儿身长约16cm,体重约100g,从外生殖器可确定胎儿性别,头皮已长出毛发,胎儿已开始出现呼吸运动。20周末:胎儿身长约25cm,体重约300g。皮肤暗红,全身有毳毛,开始出现吞噬、排尿功能。24周末:胎儿身长约30cm,体重约700g。各脏器均已发育,皮下脂肪开始沉积,因量不多皮肤仍呈皱缩状。28周末:胎儿身长约35cm,体重约1000g,皮肤粉红,皮下脂肪沉积不多。有时可有胎脂。可以有呼吸运动,但胎肺成熟度差,出生后易患呼吸窘迫综合征。若能加强护理,有可能存活。32周末:胎儿身长约40cm,体重约1700g,皮肤深红,面部毳毛已脱落,生活力尚可,出生后注意护理,可以存活。36周末:胎儿身长约45cm,体重约2500g。皮下脂肪较多,毳毛明显减少,面部皱褶消失。指(趾)甲已达指(趾)端。出生后能啼哭及吸吮,生活力良好,此时出生基本可以存活。40周末:胎儿身长约50cm,体重约3000g,发育成熟,皮肤粉红色,皮下脂肪多。指(趾)甲超过指(趾)端。男性胎儿睾丸已下降,女性胎儿大小阴唇发育良好。出生后哭声响亮,吸吮能力强,能很好存活。
