Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

The Anatomical Record, EarlyView.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Does Heart Rate Variability Predict Impairment of Operational Performance in Divers?

Sensors
We examined data from Naval Sea Systems Command grant project N0463A-12-C-001, “Hypercapnia: cognitive effects and monitoring”, with the objective of validating or repudiating heart rate variability (HRV) as a warning sign of cognitive impairment from ...

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Automated Feature Extraction and Classification of Submerged Cultural Heritage Assets in the Puck Lagoon via Multisensor Remote Sensing

Archaeological Prospection, EarlyView.
ABSTRACT This study presents a strong framework for the detection and classification of Submerged Cultural Heritage Assets (SCHA) in shallow marine environments using the integration of multibeam echosounder and airborne LiDAR bathymetry with object‐based image analysis and fuzzy logic–based classification.

Muscular Oxygen Saturation and Hemoglobin Concentration during Freediving: A Case Study

Oxygen
Lower limb muscle fatigue is the main reason for withdrawal from diving. Therefore, this study aimed to determine the local muscle oxygen saturation and hemoglobin concentration in the vastus lateralis muscle during different freediving disciplines.

Beyond Kahoot! Reflections and guidelines from a serial gamifying educator on when and how to effectively use games and game elements in anatomical education

Anatomical Sciences Education, EarlyView.
Abstract According to Nietzsche, “In every real [adult], a child is hidden that wants to play.” In everyday life, playfulness and competition can make routine or dull tasks more engaging and can offer educators opportunities to engage a learner in a more entertaining or interactive manner.

Trauma‐informed bequeathed body donor meeting sessions: A guide for creating a supportive and humanistic anatomy laboratory

Anatomical Sciences Education, EarlyView.
Abstract Anatomy educators are increasingly seeking approaches that honor the humanity of body donors while supporting learners through their first encounters in the gross anatomy lab. We describe a comprehensive donor meeting session, implemented in both dissection and prosection curricula at two North American medical schools, that prepares students ...
