Labrum
The labrum (plural Labren or Labra ) is the upper lip of certain arthropods , especially crustaceans and insects . It represents the front end of the mouthparts . It is usually designed as a plate and lies unpaired below the forehead ( clypeus ), with which it can also be fused in many insects ( clypeolabrum ). There is no homology with extremities .
The Latin word labrum "lip", "edge" is related to the Latin labium (see labium ) and German lip .
