Revised vertebral count in the "longest-necked vertebrate" Elasmosaurus platyurus Cope 1868, and clarification of the cervical-dorsal transition in Plesiosauria. [PDF]

PLoS ONE, 2013
Elasmosaurid plesiosaurians are renowned for their immensely long necks, and indeed, possessed the highest number of cervical vertebrae for any known vertebrate.

The biomechanical significance of bifurcated cervical ribs in apatosaurine sauropods

Vertebrate Anatomy, Morphology, Palaeontology, 2023
Bifurcated cervical ribs have evolved infrequently in dinosaurs. Previously documented examples include those in abelisaurid theropods, leptoceratopsid ceratopsians, and turiasaurian sauropods.

First evidence of a mandibular crest in Brasileodactylus Kellner, 1984 (Pterosauria, Pteranodontoidea, Anhangueridae), with comments on pterosaur headcrests

The Anatomical Record, EarlyView.
Abstract Brasileodactylus araripensis Kellner, 1984, is a toothed pterosaur from the Lower Cretaceous Romualdo Formation of the Araripe Basin, Brazil. Traditionally regarded as crestless, the species has been central to debates on anhanguerid taxonomy, as most members of the clade possess well‐developed sagittal cranial or dentary crests.

Morphological adaptations of cervical vertebrae in plunge‐diving sulids

The Anatomical Record, EarlyView.
Abstract Foraging strategy frequently drives morphological diversification in birds. The plunge‐diving behavior of certain species makes the functional and ecological trade‐offs of variation in cervical vertebrae an especially intriguing question. This study compares cervical vertebrae across five plunge‐diving species and two non‐plunge‐diving species,

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.

Veronica the ostrich: right cervical rib #3

, 2010
For reasons that seemed good to me at the time, I took my best shot at photographing the right cervical rib from cervical vertebra 3 of my ostrich, Veronica [see earlier Part A, Part B and Part C for context].

Spatiotemporal cellular dynamics of the notochord shape intervertebral disc morphogenesis in the mouse embryo through apoptosis and proliferation

Developmental Dynamics, EarlyView.
Abstract Background The notochord is a midline structure essential for vertebrate embryogenesis, contributing to the development of the nervous system, digestive tract, and vertebral column. In particular, notochord signaling is indispensable for proper patterning and coordinated development of alternating vertebrae and intervertebral discs (IVDs ...

Engineering an artificial trachea: Quantitative benchmarks and modular strategies for mechanics, epithelialization, and vascular integration

FlexMat, EarlyView.
In this work, we first examine the limitations of surgical repair and stenting, including migration, granulation, mucus plugging, and infection. We then translate these failures into engineering constraints involving geometry, mechanics, fixation, degradation, junctional stress, and remodeling.

FUNCTIONAL DISORDERS OF THE CERVICAL SPINE AND CERVICAL RIB SYNDROME [PDF]

, 1998
Samo kod l 0% nositelja vratnog rebra pojavljuju se kliničke smetnje. lako se radi o prirođenoj anomaliji, smetnje su rijetke prije 15. godine života. Većina autora smatra da tegobe nastaju zbog okoštavanja vratnog rebra i smanjenja tkivne elastičnosti.
