"metathorax"的定义和意义

What is "metathorax"?

The metathorax is the posterior segment of the thorax in insects and certain arthropods, positioned after the mesothorax. It serves as the attachment point for the third pair of legs and the second pair of wings. The metathorax is typically more rigid and sturdy compared to the other thoracic segments, providing stability and support during locomotion and flight. It plays a crucial role in the insect's ability to navigate and maintain balance, especially during aerial maneuvers. The metathorax contains various muscles, nerves, and respiratory structures that contribute to the insect's mobility and overall functionality. Its distinct characteristics and anatomical features make the metathorax an essential component of the insect's thoracic region.
