How would you compare the segmentation in frogs cockroach and humans?

Segmentation in frogs, cockroaches, and humans varies significantly due to their evolutionary adaptations. Frogs exhibit segmentation primarily in their skeletal and muscular systems, with a clear division between the head, trunk, and limbs, reflecting their amphibious lifestyle. Cockroaches display a more pronounced segmentation with a distinct head, thorax, and abdomen, characteristic of their arthropod class, allowing for specialized functions like locomotion and sensory perception. In contrast, humans have a more complex segmentation that is less visible externally but is evident in vertebral and organ arrangements, supporting advanced movement and organ function.
