MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

The Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

The comparative osteology of the petrotympanic complex (ear region) of extant baleen whales (Cetacea: Mysticeti).

PLoS ONE, 2011
BackgroundAnatomical comparisons of the ear region of baleen whales (Mysticeti) are provided through detailed osteological descriptions and high-resolution photographs of the petrotympanic complex (tympanic bulla and petrosal bone) of all extant species ...

Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

The Anatomical Record, EarlyView.
Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

The Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Osteology of the pectoral girdle and forelimb of Siriusgnathus niemeyerorum, a Late Triassic traversodontid cynodont from Brazil

The Anatomical Record, EarlyView.
Abstract Traversodontids are non‐mammaliaform cynodonts, herbivorous to omnivorous, that lived during the Triassic. In the Late Triassic, some members of this group increased in body size relative to other cynodont lineages and evolved postcranial adaptations associated with locomotion.

Thy-1 Deficiency Augments Bone Loss in Obesity by Affecting Bone Formation and Resorption

Frontiers in Cell and Developmental Biology, 2018
Healthy bone remodeling results from a balanced bone formation and bone resorption realized by bone-forming osteoblasts and bone-resorbing osteoclasts, respectively.

Student and staff experiences of interactive digital models when learning animal anatomy

Anatomical Sciences Education, EarlyView.
Abstract Compared to human medical sciences, digital models of animals are rare, often behind subscription services and are comparatively lacking in interactivity and accessibility features. This study explores how digital models are currently being used to teach animal anatomy, providing the data required to construct the best anatomical models ...

Retrieval Practice Through an Integrated Anatomy Laboratory Experience in a Doctor of Physical Therapy Curriculum

Clinical Anatomy, EarlyView.
ABSTRACT Gross anatomy is a foundational first‐year component of Doctor of Physical Therapy (DPT) curriculum, with limited future vertical integration. Retrieval practice and spaced learning to enhance retention are rarely embedded in second‐year DPT coursework.

The tooth-bearing skeletal elements of the Italian urodeles, a comparative tool for osteological identification

Acta Herpetologica
Urodele osteology is characterised by simplified skulls, loss of several bones and a specific sequence of cranial and limb ossification. The relatively few studies devoted to the comparative analysis of isolated urodele bones are mostly focused on the ...

Morphological features of zope, Abramis ballerus, from the middle stretch of the Odra River, Poland [PDF]

Acta Ichthyologica et Piscatoria, 2005
Background. The zope (blue bream), Abramis ballerus (L., 1758), is a cyprinid fish without economic importance, and its morphology has been poorly known. The monophyly of the genus Abramis is still unclear; therefore any new contribution to the knowledge
