Comparison of the anatomical morphology of cervical vertebrae between humans and macaques: related to a spinal cord injury model

Non-human primates are most suitable for generating cervical experimental models, and it is necessary to study the anatomy of spine in non-human when models. The purpose this was provide anatomical parameters spinal cord long-tailed macaques (Macaca fascicularis) as a basis spine-related studies. Cervical specimens from 8 male adult subjects were scanned by micro-computed tomography, an additional 10 live magnetic resonance imaging. measurements them compared those 12 human subjects. Additionally, imaging, width depth canal thickness anterior posterior cerebrospinal fluid measured relevant tendency change with segmental changes similar between species. vertebral body, canal, significantly flatter than macaques. space smaller that features vertebrae reference establishing preclinical model injury.
