The mucosa of the cervical canal (endocervix) is composed of a single layer of mucin-secreting columnar epithelium, which lines both the surface and the underlying glandular crypts. Isolated neuroendocrine epithelial cells of argentaffin type or argyrophil type are admixed with the normal endocervical cells.

Travelling in pregnancy. With the proper precautions, and armed with information on when to travel, vaccinations and travel insurance, most women can travel safely well into their pregnancy.
