Fetal Development

A CIBT Lab Exercise in Reproduction and Development

Abstract

Abstract

Students will measure pictures of developing cow embryos to generate data for size. Then, they will interpret data from graphs to determine age as well as mass. Students will then compare changes of mass during fetal development with changes in size. Finally, students will contrast developmental trends in cows with that of humans. If the dissection of the pregnant bovine uterus was done, the fetal measurements from that lab may also be included.
