Attempt the Quiz - Early Embryo  

Here are a few simple Quiz questions that relate to Early Embryo from the lecture and practical.


The allantois, cloaca, hindgut and yolk sac are all lined with endoderm



The lower end of the mesonephric duct branches to form the:

  ureteric bud
  uterus bud
  urethral bud
  gonadal bud
  none of the above


The sequential development of the renal structures within intermediate mesoderm can best be described as:

  pronephros, metanephros, mesonephros
  mesonephric duct, metanephros, mesonephros
  pronephros, mesonephros, metanephros
  mesonephric duct, paramesonephric duct, metanephros
  uteric bud, ureter, urinary bladder


An embryo that contains the XX sex chromosomal complex. In the developing gonads:

  its medullary region differentiates and its cortex regresses
  its cortical region differentiates and its medulla regresses
  the presence of an X influences medullary differentiation
  neither the presence of the X chromosome nor absence of
  the Y chromosome influences development of the ovaries
  the SRY is expressed
