General embryology I.                                                 

Aids: Set of embryological schemes and pictures (I). Atlas of Cytology and Embryology

Suggestions for self-study: 

• 1. Highlight principal differences between mitosis and meiosis, and apply the principles on spermatogenesis and oogenesis.
• 2. Define the following terms: capacitation, acrosomal reaction, and cortical reaction.
• 3. Describe an oocyte during ovulation (size, stage of meiosis, zona pellucida, cumulus oophorus).
• 4. Describe and graphically schematize the stages of early embryogenesis from fertilization to implantation (from zygote to blastocyst)
• 5. Describe and graphically schematize development of embryo and extraembryonic tissues in 2nd week of development (identify hypoblast and epiblast)
• 6. Describe and graphically schematize development of embryo and extraembryonic tissues in 3rd week of development (development of mesoderm and endoderm)
• 7. Describe and graphically schematize development of chorda dorsalis (notochord) from primitive pit, notochordal process and canal of Lieberkühn.
• 8. What is the significance of notochord during development?
