How Do You Spell ABDOMINOTHORACIC ARCH?

1. The term "abdominothoracic arch" refers to a specialized anatomical structure found in certain vertebrates, particularly in reptiles and some amphibians. It is a connective tissue bridge or supportive structure spanning the junction between the abdominal and thoracic cavities.

   The abdominothoracic arch plays a crucial role in providing structural support and facilitating movement in these animals. It acts as a bridge connecting the musculature of the abdominal wall to the dorsal muscles of the thorax. This connection enables coordinated movements of the abdominal and thoracic regions during locomotion, respiration, and other functions.

   In reptiles, the abdominothoracic arch plays a significant role in the locomotion of serpentine and lateral undulating species. It aids in generating the necessary bending forces and twisting motions for effective locomotion. Additionally, it helps to maintain the structural integrity of the body during high-speed movements and enables efficient breathing.

   The arch is composed of flexible cartilage or bony structures, allowing it to flex and extend in response to muscular contractions. Its flexibility also contributes to the overall versatility of movements in reptiles and amphibians.

   In summary, the abdominothoracic arch is a specialized structural element found in reptiles and some amphibians. It serves as a connecting bridge between the abdominal and thoracic muscles, facilitating coordinated movements, locomotion, and respiration in these animals.

2. The line of the false ribs on either side with the lower end of the sternum, marking roughly the boundary line between the abdomen and thorax.
