Anatomical and Radiological Description of the <i>Macaca fascicularis</i> Spine in Comparison with the Human Spine
Bibliographic record
Abstract
Background: This paper describes and displays the spinal radiological anatomy and associated pathology in a Macaca fascicularis and compares it to the spinal anatomy of humans. Animal models are commonly used in research. As compared to Macaca mulatta, the anatomy of M. fascicularis is less well described in the literature. Materials and methods: The authors anatomically reconstructed and reviewed the defleshed spine of a single adult M. fascicularis visually, radiographically, and with high resolution CT. Results: 7 cervical, 12 thoracic, 6 lumbar, 3 sacral, and 16 caudal vertebrae were identified. Similarities in the spine to humans were seen as well as differences such as the beaked anterior arch of C1, the anterior pointed lower lumbar vertebrae, the upward curved transverse processes, and presence of three sacral segments. Degenerative changes were seen at multiple locations similar to humans though most pronounced at T3-4. Conclusions: This paper addresses the normal spinal anatomy and degenerative changes in an adult M. fascicularis and compares it to humans.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
