Structural components of the normal thoracic and lumbar vertebrae in rats

Abstract

The relevance of this topic is determined by the fact that laboratory animals are widely used in experimental morphology. The most widely used ones are rats [1-7]. There are a number of studies in which the authors cover in detail the normal morphological state of various organs of rats and its changes under experimentally simulated pathological conditions [8-12]. The available studies on the rats' musculoskeletal system and spine highlight this topic insufficiently. Aim. We aimed to study the structure of the normal thoracic and lumbar vertebrae in the rats. Materials and methods of research. The objects of our study were 15 sexually mature outbred male rats, weight 80 g, age 4,5 months. All animals were kept in a vivarium. Keeping, care, labeling, and all other manipulations were carried out in accordance with with 'the European Convention for the Protection of Vertebrate Animals Used for
