ABB Embryology study plan
ABB Embryology · Give each week a clear focus.
8 weeks · About 6 hours per week
Gametogenesis and Reproductive Anatomy & Fertilization and Early Embryonic Development
Diagram the stages of spermatogenesis and oogenesis, labeling ploidy and chromosome content at each step
Explain the hypothalamic-pituitary-gonadal axis and the hormonal events of the menstrual cycle
Describe the functional anatomy of the male and female reproductive tracts relevant to gamete collection and transport
