Abstract Background Kuruma shrimp ( Marsupenaeus japonicus ) is a commercially important crustacean and valuable global food source. This study employed scanning electron microscopy (SEM) to explore the morphology morphometric features of cephalothoracic structures, including antennules, antennas, scaphocerite, rostrums, eye stalks. The primary focus was on understanding role each part, especially through examination setae, which are crucial for chemoreception defense. Additionally, energy dispersive X-ray spectroscopy (EDX) analysis utilized identify elemental composition these structures. Material methods samples from heads fifteen were studied by gross morphometry, SEM, EDX analysis. first integrate both SEM techniques detailed offering an innovative approach morphological characteristics. Results exhibited two antennules antennae. antenna featured four basal segments: basicerite, ischiocerite, merocerite, carpocerite, with distinctive articulations setae distribution. antennule, three segments covered plumose displayed curved cone-shaped flagellae. resembling paddle, showcased while rostrum dorsal ventral spines, lateral grooves, unique setal arrangements. Setal measurements across structures revealed diverse lengths widths, indicating functional specialization. compound eyes connected optic stalk adorned setae. higher percentages calcium phosphorus in spear-like rostrum, antenna, respectively. Conclusion investigation provides thorough intricate region , shedding light its sensory defensive capabilities. novel application not only deepens our insights into but also lays groundwork future studies using this dual morphology, potential advantages sustainable aquaculture conservation marine ecosystems.

The study design was prospective and descriptive of the horse stifle joint using CT, sectional anatomy, SEM, EDX analysis. 3D rendered-volume reconstruction CT horse's allows good visualization large small bony structures ligaments, or menisci. In addition to sagittal section subsequent bone window cross sections, which provided detailed images structures, muscles, matched with anatomical sections. is described SEM synovial membrane had varied villi in length shape: long short tongue shapes different tip dome-shaped, single branched folds. scratched surface revealed a network collagen fibers arranged various directions, layers, deep synoviocytes. SEM-EDX Spectra identified following items joint's meniscus ligaments: sample contained carbon, oxygen, nitrogen, sulfur, calcium, phosphorus, selenium replaced by sulfur at meniscus. Four specimens were examined determine their carbon oxygen percentages. Calcium phosphorus levels measured, highest concentrations lowest collateral patellar ligaments. percentage determined, ligaments higher than menisci, particularly cruciate whereas menisci silicon. Knowledge macro- microscopic normal anatomy obtained through guide reference for determining stifle's soft tissue microstructures, as well chemical structure membrane,
