Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

open access: yesJournal of Anatomy, EarlyView.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...

An investigation of the functional significance of the pyramidalis muscle using shear wave elastography

open access: yesJournal of Anatomy, EarlyView.
The pyramidalis (Py) is a small triangular‐shaped anterior abdominal wall muscle, the function of which remains uncertain. We used shear wave elastography to test the hypothesis that Py contributes to stiffness of the linea alba. Our results indicate that Py contraction results in a significant increase in LA stiffness, supporting the previously ...

How do forelimb long bones adapt in rhinoceroses? An in‐depth examination of their microanatomy

open access: yesJournal of Anatomy, EarlyView.
Here, we study the bone structure in the forelimb long bones of the five extant species of rhinoceroses. By combining traditional description of virtual sections made on the bones (A) with in‐depth cartographies of the variation of bone compactness and anisotropy (B), we show how bone tissue can adapt to extreme forces and constraints in the second ...
