Study Notes
Embryology and Pregnancy Development
- Embryology is the study of development from fertilization to birth
- The pregnancy length is about 266 days or 38 weeks after fertilization
- Prematurity is defined as birth before 37 weeks from the last menstrual period
- Overdue, or post-term, refers to birth after 40 weeks from the last menstrual period
- Development in utero is divided into germinal, embryonic, and fetal periods
- Pregnancy begins when the egg is fertilized by the sperm, forming a zygote
- The zygote undergoes cleavage, forming a blastocyst with outer and inner cell masses
- Implantation of the blastocyst occurs in the uterus by day 6-7 after fertilization
- Ectopic pregnancy occurs when the fertilized egg grows outside the uterus
- It is most common in uterine tubes and can be life-threatening if left untreated
- Ectopic pregnancy occurs in about 2% of all pregnancies and is a main cause of maternal death in the first trimester
- Symptoms of ectopic pregnancy include missed periods, nausea, and breast swelling
