labrum
1. In Echinozoa, a lip-like projection of the peristome.

2. A broad piece of cuticle which forms the upper ‘lip’ in an insect. The labrum articulates with the clypeus. It is anterior to the mandibles, and can be moved away from them by a pair of muscles, or closed down on to them by another pair of muscles with a rocker-like action.
