Summary: The study examined bilateral motor control of the epaxial musculature in feeding and locomotion in bluegill sunfish, finding that high-performance feeding activates all epaxial musculature while locomotion activates all three epaxial regions. Fast-starts showed the highest activation intensities, with high-performance suction feeding occasionally reaching near-maximal intensity.

Summary: Macronaria, a group of sauropod dinosaurs, includes both colossal and small species. Using microCT, researchers studied the braincase and inner ears of Europasaurus holgeri, a Late Jurassic dwarf sauropod. The finding of adult inner ears in juvenile specimens suggests precociality. This study adds to the understanding of neurovascular anatomy in sauropods and supports their reputation as fast-growing giants with diverse reproductive and social behavior.

Summary: The study found that a two-month yoga-based breathing intervention in young endurance athletes led to changes in breathing characteristics during exercise, with more reliance on abdominal and thoracic musculature and less recruitment of subclavian musculature. This more efficient ventilatory muscular recruitment may benefit endurance performance by reducing energy demand and optimizing energy requirements for mechanical work.

Summary: In recent years, muscle-preserving techniques in cervical single-door laminoplasty have been modified to protect the spinous processes and reconstruct the posterior musculature. The purpose of this study is to quantitatively evaluate the biomechanical effects of these modified laminoplasty procedures. The results showed that modified muscle-preserving laminoplasty is superior to classic laminoplasty due to the biomechanical effect of the posterior musculature reconstruction.

Summary: The elephant trunk functions as a muscular hydrostat and consists of complex musculature. The dexterous finger is composed of microscopic radial fascicles, suggesting the importance of muscle miniaturization in elephant dexterity. The trunk-shaft muscles show lateral symmetry and are comprised of various types of longitudinal and radial fascicles. The number of trunk muscle fascicles is estimated to be around 90,000.

Summary: This study verified the number and perforating points of all perforators around the LD lateral border through anatomical study and clinical practice, proposing a concept of an abundant cutaneous perforator system in the lateral thoracic region and developing a promising method for clinical application of lateral thoracic WPS flap with large survival area and relatively simple procedure even with muscle-preserving techniques.

Summary: Mechanization has led to the success of modern agriculture, but the increased weight of farm machinery has raised concerns about subsoil compaction. Research shows that 20% of arable land is at risk of chronic subsoil compaction, leading to potential loss of productivity. The study also suggests that prehistoric giants may have had similar effects on land productivity due to subsoil compaction.

Summary: This study reconstructed the hindlimb musculature of the basal therizinosaur Falcarius utahensis using muscle scars, information from extant birds and crocodylians, and models of Tyrannosaurus rex. The results suggested that the evolution of opisthopubic pelvis, muscular changes, avian stance, and mode of walking occurred more than once.

Summary: Therizinosaurs are a group of unusual theropods from the Upper Cretaceous of Asia and North America, with representatives like the large Nothronychus. Despite their well-developed forelimbs and pectoral girdle, they share similarities with traditional carnivorous theropods. Their musculature indicates a mix of primitive and derived characters, akin to dromaeosaurs.

Summary: This study provides a new, 4D anatomical characterization of developing human upper limb muscles, showing the progressive wave-like development of muscles and key events in muscle formation. Some muscle bundles undergo splitting to form individual muscles, while others translocate to reach their correct positions. Furthermore, it is revealed that palmaris longus fails to form early in development.

Summary: Muscle shortening is the foundation of skeletal motion and animal performance. Swimming fish face difficulties in achieving homogeneous muscle shortening due to the deformations of their bodies. Our experiment found that the dorsal muscles of fish experience both dorsoventral and mediolateral gradients in longitudinal strain.

Summary: Human gross anatomy has not fully integrated modern embryological findings, leading to discrepancies between traditional knowledge and recent molecular studies. To resolve the disagreement, a novel hypothetical model of spinal nerve ramification is proposed, based on the previously unknown developmental process of intercostal nerves. This model explains the branching pattern of spinal nerves in line with the developmental context of target muscles, providing valuable insights for basic and clinical sciences.

Summary: Researchers have discovered a new sauropod ichnotaxon, Iniestapodus burgensis, in Spain, characterized by distinctive hand and foot impressions, potentially made by a non-titanosaurian titanosauriform dinosaur. The study suggests that Iniestapodus trackmakers were solitary individuals from different age classes, often found in the Las Sereas shallow lacustrine-palustrine areas.

Summary: The study found that there are fundamental differences in suckling and drinking processes between mammalian infants and adults. By measuring the activity of muscles during infant feeding, it was discovered that muscle orientation changes with age, but the timing of activation and contractile patterns remain relatively stable. As infants transition to solid foods, the neuromotor system may be optimized for this change.
