    Embryo Develoment Embryo Develoment Presentation Transcript

    • Early Embryonic Development
      • Define these terms …
      • Ovary
      • Fallopian tube
      • Uterus
      • Fertilization
      • Zygote
      • Cleavage
      • Morula
      • Blastula (Blastocyst)
      • Implantation
    • What is a blastocyst?
      • During the second week, cells in the wall of the blastocyst will begin to fold inward.
      • Consequence of gastrulation :
      • A hole is now present on the side of the blastocyst – it is called the blastopore .
      • Cell layers are formed in the gastrula .
      • The innermost layer of cells is called the endoderm .
      • The middle layer of cells is called the mesoderm .
      • The outer layer of cells is called the ectoderm .
      • Cells are becoming specialized. Cell differentiation is occuring – they are becoming differentiated. They are changing from undifferentiated  differentiated
    •  
      • In vertebrates, Gastrulation is followed by Neurulation … the development of the nervous system. (change in body symmetry)
      • By day 21, embryonic membranes have also formed:
      • The Amnion  develops into a fluid filled sac. (cushions and protects baby)
      • The Chorion  along with the lining of uterus forms the Placenta , the embryo’s organ for respiration, nourishment, and excretion. (The placenta allows the embryo to make use of the mother’s organ systems while its own are developing.)
      • Materials diffuse between baby and mother – there is no direct blood link between the two…
      • Umbilical cord – attached to baby and placenta
