FERTILIZATION AND EMBRYOLOGY

Cards (26)

  • It is the last phase in the process of fusing two haploid eukaryotic cells together
    Karyogamy
  • It refers to the fusion of the two nuclei.
    Karyogamy
  • It is a fertilized eukaryotic cell that forms after the union of male and female gametes.
    Zygote
  • It encompasses the study of how organisms grow and develop from a single cell to a complex multicellular organism.
    Developmental Biology
  • It is the process by which a sperm cell fuses with an egg cell to form a zygote, initiating embryonic development.
    Fertilization
  • It usually takes place in a fallopian tube that links an ovary to the uterus.
    Fertilization
  • Where do fertilization typically occurs?
    Fallopian tube
  • This formation marks the beginning of embryonic development.
    Diploid Zygote
  • This cell contains two sets of chromosomes (2n).
    Diploid
  • These cells undergo mitosis.
    Diploid
  • These cells are formed by the process of meiosis.
    Haploid
  • This cell contain only one set of Chromosomes (n).
    Haploid
  • It is the outer layer that forms the exoskeleton.
    Ectoderm
  • It is the middle layer that develops into organs.
    Mesoderm
  • It is the inner layer that forms the inner linings of organs.
    Endoderm
  • During this process, the blastocyst undergoes a series of morphogenetic movements, leading to the formation of three primary germ layers: ectoderm, mesoderm, and endoderm.
    Gastrulation
  • What are the three primary germ layers?
    1. Ectoderm
    2. Mesoderm
    3. Endoderm
  • It is a cluster of dividing cells made by a fertilized egg. It is the early stage of an embryo.
    Blastocyst
  • It refers to a rapid cell division that leads to a multicellular embryo.
    Cleavage
  • The zygote undergoes rapid cell divisions called cleavage, leading to the formation of a multicellular structure called a blastocyst. 
  • It is a multicellular structure which is formed after cleavage.
    Blastocyst
  • This event involves the formation and differentiation of specific tissues and organs from the germ layers.
    Organogenesis
  • During this event, the embryo develops into a fetus, with organs and body structures becoming more complex and functional.
    Fetal Development
  • It is a developing offspring post-embryonic stage until birth.
    Fetus
  • It refers to the culmination of embryonic development, where the fully formed organism exits the maternal reproductive system and begins independent life.
    Birth
  • It also encompasses the study of developmental abnormalities, such as birth defects, and the mechanisms underlying regeneration and tissue repair in organisms.
