3 Topics 配子的形成與受精 受精卵的著床與胚胎成形 各系統的正常或異常發育與臨床疾病的關係 畸胎學

4 Embryology Animal development is a continuous process that begins when a zygote is formed Development does not stop at birth

5 Developmental Periods
Gametogenesis Spermatogenesis Oogenesis Prenatal period (Fertilization) Embryo: Zygote Cleavage Implantation Gastrulation… Organogenesis Fetus Postnatal period Neonate (<1 month) Infancy (< 1 yr) Childhood Puberty (13 yr – 16 yr) Adulthood

6 胎齡: LNMP (last normal menstrual period) embryo fetus Trimester

7 Carnegie stages are a system used by embryologists to describe the apparent maturity of embryos
1st trimester

8

9 1st week

10 Formation of Bilaminar Embryonic Disc
Stage 5: 7th –12th day full implantation 2nd week

11 Stages 6-9: Day 13-21 Somites 3rd week

12 Stages 10-17 4th to 6th week

13 Embryo (end of the 8th week) - all major structures are present
7 8 Embryo (end of the 8th week) - all major structures are present Fetus (after 8th week)
