10. Microscopic anatomy of the female reproductive tract

• What is the significance of the transformation zone of the female reproductive tract?

  Show Answer

  Correct answer:
  The transformation zone marks the transition between glandular epithelium of the cervical canal (endocervix) and stratified squamous epithelium of the ectocervix, the portion of the cervix visible in the vagina. The transition zone is a common site for dysplastic changes found on cervical Pap smears, and these changes can become malignant if not monitored.
