pectinate line
The pectinate line (anocutaneous line, dentate line, anorectal junction) is a line which divides the upper 2/3rds and lower 1/3rd of the anal canal. Developmentally, this line represents the hindgut-proctodeum junction. It is an important anatomical landmark, and several distinctions can be made based upon the location of a structure relative to this line: [ http://en.wikipedia.org/wiki/Pectinate_line ]
