Determination of Sex using Foramen Magnum Measurements: A Cross-sectional Study from Karur, Tamil Nadu, India [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Sex determination is a fundamental goal in both forensic analysis and archaeological studies. The foramen magnum, the largest opening in the base of the skull, carries vital structures from the brain to the spinal cord.

Ancestral determination from foramen magnum

, 2010
Ancestry estimation is a crucial part of the biological profile creation in forensic anthropology. Without proper classification of ancestry, other aspects of the biological profile, such as stature, can be affected.

The (extended) achondroplasia foramen magnum score has good observer reliability [PDF]

, 2022
Background Achondroplasia is the most common skeletal dysplasia. A significant complication is foramen magnum stenosis. When severe, compression of the spinal cord may result in sleep apnea, sudden respiratory arrest and death. To avoid complications,

Foramen Magnum Tumors

Neurologia medico-chirurgica, 1982
Tumors of the foramen magnum are rare and the incidence is between 1.6% and 2.4% of all spinal tumors; therefore the personal experiences of one neurosurgeon with this type of tumor are necessarily limited. This unfamiliarity, combined with the curious presentation of some of the lesions due to the complex anatomy of this region, has made the diagnosis

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

The Anatomical Record, EarlyView.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.
