myoepithelial

views updated

myoepithelial (musculo-epithelial) In hydras, applied to the most conspicuous cells of the ectoderm. They are columnar in form, with contractile processes extending into the mesogloea and broad outer bases which meet to form a continuous sheet. In some coelenterates (e.g. jellyfish) the epithelial part of the cells may be reduced.
