Which term denotes the jaw structure used for feeding in many animals?

• A. Abdomen
• B. Jaws/Mandible
• C. Spinnerets
• D. Cephalothorax

Answer: (B)

Feeding relies on the jaw structure called the mandible, often referred to as jaws. The mandible is the lower jaw bone in vertebrates and forms the main biting and chewing mechanism, moving against the upper jaw to crush food. In many insects and other arthropods, the paired mandibles are strong mouthparts specialized for cutting, tearing, or grinding food. The other terms point to unrelated body parts: the abdomen is a body segment housing organs, spinnerets are silk-spinning organs in spiders, and the cephalothorax is the fused head and thorax region in some arthropods. So the term that denotes the jaw structure used for feeding is jaws/mandible.
