A New Model of Feeding Biomechanics Based on Tied‐Arch Principles

Integrative Zoology, EarlyView.
This new biomechanical model explains the major stress and strain patterns generated through the cranium during biting. The model proposes that the cranium resolves bite‐induced reaction forces through arcs of compressive stress that span the cranial structure between biting teeth and both jaw joints.

Updating the forelimb anatomy of the domestic cat (Felis catus, Felidae) based on evolutionary inferences of its muscles and nerves I: Shoulder and brachium

Journal of Anatomy, EarlyView.
In this study, we provide a detailed description of the shoulder and brachium muscles and the brachial plexus of the domestic cat (Felis catus). We identified muscular variants (articularis humeri, coracobrachialis longus, biceps brachii caput breve), clarified the independence of the anconeus medialis muscle from the triceps brachii muscle, and ...

Can we use the contralateral glenoid cavity as a reference for the measurement of glenoid cavity bone loss in anterior shoulder instability?. A comparative analysis of 3D CT measurements in healthy subjects

, 2018
Kose, Ozkan/0000-0002-7679-9635The purpose of this study was to compare the glenoid cavity measurements in healthy subjects. 100 adult subjects without shoulder pathology who had pulmonary computed tomography for any reason, were included in the study ...

Comparative histological analysis of vertebrates reveals Triassic climate variability across southern Pangea

Journal of Anatomy, EarlyView.
Bone tissues of Triassic taxa reveal life history signals consistent with climatic variation across southern Pangea, spanning present‐day Brazil, Argentina, Zimbabwe, and India. Slower growth patterns within the Zimbabwean assemblage suggest a comparatively more arid intracontinental environment than those closer to the coast. Artwork by Andrey Atuchin.

Comprehensive analysis of bony scapula morphology and anthropometry in a homogeneous population

BMC Medical Imaging
Background The shoulder joint has consistently drawn the interest of radiologists, physiologists, and orthopaedic surgeons. The precise measurements and geometry of the scapula are crucial to understanding shoulder pathomechanics.

Modified axillary radiograph of the shoulder: a new position

Revista Brasileira de Ortopedia
Obtaining axillary radiographs of the shoulder in acute trauma is not always feasible. The authors present a new modification of this radiographic view, in order to assess the anatomic relationship between the humeral head and the glenoid cavity.

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Bone histological evidence for posture‐related load transmission in the talpid pectoral girdle

Journal of Anatomy, EarlyView.
Bone histology of the clavicle and scapula revealed distinct load‐bearing roles within the mammalian pectoral girdle associated with different forelimb postures. Hyper‐abducted moles exhibited an enhanced load‐bearing role of the clavicle, whereas the parasagittal shrew exhibited histological features consistent with the scapula acting as the principal

Reconstructing the major skull myology of the giant stem‐amphibian Mastodonsaurus: A case study for early tetrapods

Journal of Anatomy, EarlyView.
We reconstruct the major cranial musculature of the giant stem amphibian Mastodonsaurus giganteus, revealing a differentiated jaw‐adductor system, a probable sesamoid pulley, and previously unrecognised muscles. This EPB‐based case study establishes an anatomical framework for modelling feeding in early tetrapods and supports interpretations of ...

Morphometrical Analysis of Glenoid Fossa of Scapula with Multidetector Computed Tomography in a Tertiary Care Hospital in India

National Journal of Clinical Anatomy
Background: Morphometric analysis of the glenoid fossa is crucial for understanding shoulder biomechanics, guiding orthopedic procedures, and designing population-specific implants.
