Abstract
Purpose: Due to the difficulty of using neural tracers in humans, knowledge of the nociceptive system's anatomy is mainly derived from studies in animals and mainly in rats. The aim of this study was to investigate the morphological differences of the ascending spinal nociceptive pathways between the rat and the macaque monkey; in order to evaluate the variability of this anatomy during phylogenesis, and thus to know if the anatomical description of these pathways can be transposed from the rat to the human.
Methods: A review and analysis of the literature were performed. The criteria used for comparison were: origins, pathways, their terminations in target structures, and projections from target structures of ascending spinal nociceptive pathways. The monkey was used as an intermediate species for comparison because of the lack of data in humans. The hypothesis of transposition of anatomy between rat and human was considered rejected if differences were found between rat and monkey.
Results: An anatomical difference in termination was found for the spino-annular or spino-periaqueductal grey (spino-PAG) pathway and transposition of its anatomy from rat to human was rejected. No difference was found in other pathways and the transposition of their anatomy from rat to human was therefore, not rejected.
Conclusion: This work highlights the conservation of most of the ascending spinal nociceptive pathways' anatomy between rat and monkey. Thus, the possibility for a transposition of their anatomy between rat and human is not rejected.
期刊介绍：
Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit.
Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest.
Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems.
Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
