Within 12-24 hours
Study Notes
Embryological Development
- Embryology is the study of the development of the embryo and fetus from fertilization to birth.
- A single fertilized cell divides by mitosis to produce all the cells in the body.
- Human development starts with the fusion of the female egg cell (secondary oocyte) with the sperm cell, which contains a haploid number of chromosomes.
Gametogenesis and Fertilization
- The ovum is released from the follicle of the ovary by the process of ovulation.
- The ovum then enters the uterine tube, where fertilization normally takes place in its ampulla within 12-24 hours after ovulation.
Prenatal Development
- Prenatal development involves a complex sequence of cell growth, differentiation, and organization.
- Embryology encompasses the entire process, from the formation of male and female germ cells (gametogenesis) to the formation of a full-term infant ready to enter the outside world.
