Study Notes
Fertilization
- Fusion of male sperm and female ovum to form a diploid zygote.
- Results in genetic diversity due to the combination of parental DNA.
Cleavage
- Initial rapid cell division of the zygote following fertilization.
- Leads to the formation of a multicellular structure called the blastomere.
- No increase in overall size; division occurs without growth.
Blastula Stage
- Characterized by the formation of a hollow sphere of cells known as the blastula.
- Contains a fluid-filled cavity called the blastocoel.
- Sets the stage for subsequent developmental processes.
Gastrulation
- A critical phase where the blastula reorganizes into a three-layered structure.
- Formation of germ layers: ectoderm, mesoderm, and endoderm.
- Establishes the basic body plan and structure of the embryo.
Mesoderm Development
- The mesoderm gives rise to muscles, bones, and the circulatory system.
- It plays a key role in forming internal organs such as the heart, kidneys, and gonads.
- Responsible for the development of connective tissues and certain immunological components.
