👋Hi new followers! 👋
At @JournalofAnat, we seek to advance the understanding of all aspects of human and comparative anatomy through the analysis of structure, function, development, and evolution.

Human femur study shows that thicker cortices produce less porous secondary osteons—independent of age, sex, or lifestyle—but this pattern doesn’t hold in females. Allometry matters for interpreting bone remodelling.

Congratulations on this excellent new contribution to our understanding of proboscidean biomechanics! 🐘
New OA paper out in @JournalofAnat 🐘 In this study lead by MSc student Nicolas Wagner; we investigate compressive loading in proboscidean (elephants & their extinct relatives) using FEA and highlight different mechanical strategies 🦾 doi.org/10.1111/joa.70234

🚨 New issue alert! 🚨
Birds that use the tail for courtship display have unusually shaped and proportionally heavier tail muscles than birds that don't exhibit these displays, highlighting a how courtship behaviours shape the structure and function of muscles in these animals.

New research in @JournalofAnat maps the development of chicken abdominal musculature. Authors follow somites 24–28, revealing the origin of fibres. Muscle fibres appear to mix across segments, but never fuse, giving a glimpse into how complex abdominal muscles take shape.

This month @BrainPaleo explores direct comparison of brains and endocasts in the same 75 individuals, showing that sulcal imprints are short and discontinuous. A new class of endocranial marks are identified, proposing a new standard for interpreting fossil endocasts.

Enamel histology may provide insights into dental growth & life history traits, but its study in fossils is challenging due to increments identification. This standardized methodological framework helps identify enamel increments correctly, step by step doi.org/10.1111/joa.70098

The intervertebral disc has a fat pad structure. This Intervertebral Fat Pad (IVFP) is newly described in this paper that shows its existence in multiple species and suggesting a function role in disc health and degeneration.

Pluchot et al describe the six-layered structure of the sheep auditory cortex, noting the likely location of the primary auditory cortex. They show that its organization is similar to that of other mammals, supporting the use of ovine models for auditory processing studies

New cadaveric evidence supports the tubarial gland as a distinct anatomical structure, with complete histological validation and the first published description of a macroscopic excretory duct. The findings strengthen the anatomical evidence for a discrete gland in this location.

Despite muscular variations, the posterior layer of the thoracolumbar fascia consistently contains collagen bundles oriented in an inferolateral direction from the lumbar spine to the iliac crest, independent of the orientation of the muscular aponeuroses: doi.org/10.1111%2Fjoa.70078

Showcasing the first issue of Volume 249 with work by @tomi_susi. Bichir pectoral fins carry unique "dental plates" (dermal elements bearing tooth-like odontodes) that continuously replace themselves, much like oral teeth. A fascinating link between scales, teeth, and locomotion.

Scheidt et al., investigate the scaling of internal joint distance (IJD), a surrogate measure for cartilage thickness, across small- to medium-sized mammals.
Elbow position had no significant effect on IJD and used these data to model the range of motion (ROM) at the elbow joint

Their study also provides a workflow for measuring IJDs and ROM, and for assessing how these variables are influenced by body mass and locomotor behaviour.

Our new special issue explores how joints shaped vertebrate evolution through biomechanics, development, anatomy and palaeontology, revealing joints as dynamic interfaces where structure, function and history converge. onlinelibrary.wiley.com/toc/…

This month Campbell et al. study the electroreceptor ribbon synapses in sturgeon lateral line organs. They found that these synapses in non-teleost ray-finned bony fish are glutamatergic, suggesting further commonalities, but also some differences, with hair cell ribbon synapses.

Another from the Special Issue - @Paxton_Lab showcase a new methodology for gaining accurate dimensions of soft tissues during #dissection. Many methods overlook the laxity of soft tissue when describing dimensions and use a 'point-to-point- approach.

By using the lateral ligaments of the #ankle at various joint positions, they validate a new approach, which allows for better characterisation of soft tissues for future surgical repair and tissue engineered replacement design. doi.org/10.1111/joa.14267
