Key Hormone for Pregnancy

• Main Hormone:

  • The primary hormone associated with pregnancy is progesterone.

Stages of Embryonic Development

• Cleavage Stage:

  • This is the initial stage where the zygote undergoes cell division without growth.

  • The zona pellucida is involved in this stage but will change names as the stages progress.

• Embryonic Stage:

  • Second stage of development, significant for the formation of the embryo.

  • Major development occurs in this stage including the formation of basic structures and organs.

• Fetal Stage:

  • Final stage of prenatal development.

  • This stage focuses on growth and maturation of the already formed structures from the embryonic stage.

Exam Preparation Notes

• Exam Focus:

  • Be aware of the stages of pregnancy as this information is critical for understanding development.

  • Emphasis on the embryonic and fetal stages.

  • Clarification: Pregnancy determination info will not be included in the exam, so focus on the stages of development instead.

Additional Thoughts

• It’s noted that grades aren't indicative of understanding or capability; focus on comprehension rather than performance metrics.

• Preparation encompasses detailed understanding beyond what's strictly tested; engaging with broader knowledge is encouraged.
