Structural components of the normal thoracic and lumbar vertebrae in rats

The relevance of this topic is determined by the fact that laboratory animals are widely used in experimental morphology. most ones rats [1 - 7]. There a number studies which authors cover detail normal morphological state various organs and its changes under experimentally simulated pathological conditions [8 12]. available on rats’ musculoskeletal system spine highlight insufficiently. Aim. We aimed to study structure thoracic lumbar vertebrae rats. Materials methods research. objects our were 15 sexually mature outbred male rats, weight 80 g, age 4,5 months. All kept vivarium. Keeping, care, labeling, all other manipulations carried out accordance with ‘the European Convention for Protection Vertebrate Animals Used Experimental Other Scientific Purposes’ [Strasbourg, 1985], ‘Ethical principles animal experiments’, approved First National Congress Bioethics [Kyiv, 2001], Law Ukraine № 3447 IV ‘On protection from cruel treatment’. was Commission Danylo Halytsky Lviv Medical University declared met ethical requirements according order Ministry Health 231 November 1, 2000 (protocol 10 December 26, 2011), №2 February 20, 2012 year). Before sampling, sedated dibutyl ether. Skeletalized rat bones as material macroanatomical structural components vertebrae. spines dissected after euthanasia, then boiled four hours, followed careful separation remained soft tissues. obtained treated solution hydrogen peroxide following photography different projections identify anatomical structures involved formation Photography made using digital camera Nikon D 3100. Results. spinal column preparations white, weighing aged 4.5 months use set revealed lot aspects lower consists form divisions. 57 spine. cervical division represented 7 vertebrae, 13, 6, sacral 4 caudal 27 Conclusions: As result study, we identified morphology studied
