... of the anterior retractor muscle during development, as measured by micro-computed tomography (micro-CT) scans of buccal masses. Consequently, larger A. californica did not need to activate their muscles as fully to produce equivalent forces. These results indicate that muscle activation may be an important...

... differences, suggesting anterior–posterior specialization. Principal planta retractor muscle Morphology Micro-CT Soft body locomotion Animal movements depend on a complex interaction between neural commands, muscle function, and the shape and material properties of the body. For animals...

... hearing may be a sensory development anomaly. Table 2. Estimated least squares means differences in hearing thresholds between the more and less sensitive hearing clusters To characterize the development of the ear structures, we used micro-CT scanning and histology. Because of limited...
