A novel mouse model simulating C5 palsy after cervical surgery
Animal Models and Experimental Medicine, EarlyView.This study establishes a reliable mouse model of permanent C5 palsy (post‐laminectomy complication) via dorsal approach, selectively severing the C5 anterior nerve root while preserving the posterior root through partial C4 and C5 laminectomy. The model successfully replicates clinical C5P features—flaccid shoulder paralysis, electrophysiological ...

A further study of the Quaternary antelopes of Shelter Cave, New Mexico [PDF]
, 1932 Since the preliminary description of Tetrameryx? conklingi from Quaternary deposits in Shelter Cave, New Mexico, additional materials of this interesting antilocaprid species have been obtained in the course of further excavations in the cavern by Mr. R.

The Anatomical Record, EarlyView.Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Skull base bone hyperpneumatization
Journal of the Belgian Society of Radiology, 2013 A 50-year-old male with a long standing history of compulsive Valsalva maneuvers, complaining of episodes of vertigo underwent head computed tomography. Axial CT slices at the level of the skull base (Fig. A) and the first cervical vertebrae (Fig.

Fossil evidence and stages of elongation of the Giraffa camelopardalis neck [PDF]
Royal Society Open Science, 2015 Several evolutionary theories have been proposed to explain the adaptation of the long giraffe neck; however, few studies examine the fossil cervical vertebrae. We incorporate extinct giraffids, and the okapi and giraffe cervical vertebral specimens in a

The Anatomical Record, EarlyView.Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Temporal and phylogenetic evolution of the sauropod dinosaur body plan [PDF]
, 2016 The colossal size and body plan of sauropod dinosaurs are unparalleled in terrestrial vertebrates. However, to date, there have been only limited attempts to examine temporal and phylogenetic patterns in the sauropod bauplan.

The Anatomical Record, EarlyView.Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

EvoDevo, 2011 Background Mammals as a rule have seven cervical vertebrae, except for sloths and manatees. Bateson proposed that the change in the number of cervical vertebrae in sloths is due to homeotic transformations. A recent hypothesis proposes that the number of

The neck of Barosaurus was not only longer but also wider than those of Diplodocus and other diplodocines [PDF]
, 2016 Barosaurus is a diplodocid sauropod from the Upper Jurassic Morrison Formation of the western United States, and is known for its very long neck. It is related to the sympatric Diplodocus, and often thought of as more or less identical except with a ...
