There are many minerals that are considered to be essential, meaning our bodies must have them. Some minerals are described as bulk minerals and others are trace minerals. This simply means that our bodies require more of the bulk minerals and literally, trace amounts of the trace minerals. Donât be fooled by these small amounts because every mineral plays an important role to our health and affects our bodies in some way.
Medical Definition of Mandible. Mandible: The bone of the lower jaw. The joint where the mandible meets the upper jaw at the temporal bone is called the temporomandibular joint. Last Editorial Review: 6/9/2016.
Insect mandibles are a pair of appendages near the insectâs mouth, and the most anterior of the three pairs of oral appendages (the labrum is more anterior, but is a single fused structure).Their function is typically to grasp, crush, or cut the insectâs food, or to defend against predators or rivals.ll but a few adult Lepidoptera lack mandibles, with the remaining mouthparts forming an elongated sucking tube. The exception is the mandibulate moths (family Micropterigidae), which have fully developed mandibles as adults.
