Attempt the Quiz - Early Embryo  

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

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


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

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

3 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

4 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
