Human Uterine Tube Ciliated Epithelium SEM

Uterine epithelial cilia are responsible for the initial movement of the ooycte and conceptus (zygote, morula, blastocyst). In humans, during the first week of development.

The differences in size and shape of cilia and microvilli are well illustrated by scanning micrographs of the lumenal surface of the epithelium lining the mammalian oviduct.

  • The tufts of cilia associated with individual ciliated cells project several microns above the convex apices of nonciliated cells covered with short microvilli.
  • The number of ciliated cells in this epithelium is under hormonal control by estrogens.
Cilia
  • long processes
  • epithelial cell apical membrane specializations
  • microtubule filled motile structure

Microvilli

  • short processes
  • epithelial cell apical membrane specializations
  • microfilament filled non-motile structure
