Description
A general overview of the physical properties of the HII regions is
presented here, emphasizing the various general models made to explain
their structure and behaviour. The Lyman continuum effective extinction,
representing a measure of the extinguished or lost fraction of the
ionizing flux, is explained briefly, and the results of a study
performed on this matter are presented. This study, based on a sample of
about 200 HII regions of the galaxy M51 using high resolution images
acquired with the HST, suggests a highly inhomogeneous structure.
