The Anatomical Record, EarlyView.Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Fused Axis Vertebrae With A Third Cervical Hemivertebrae - A Rare Case Report.
IOSR Journal of Dental and Medical Sciences, 2013 Congenital anomalies are common in the vertebral column. Skeletal abnormalities at the cervical region may result in severe neck pain and sudden unexpected death. During the osteology demonstration of cervical vertebrae for the MBBS students, it was observed that one of axis vertebra is fused with the 3rd cervical hemivertebrae.

The Anatomical Record, EarlyView.Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs
The Anatomical Record, EarlyView.Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.
