Plastination of Plexuses Brachialis, Lumbosacralis And Cauda Equina Using In Education Of Neuroanatomy Of The Goat

Document Type : Original Article



Plastination of nervous tissue has become a very important tool in teaching neuroanatomy. Also, plastinated nervous specimens can be used to study the anatomical relations in clinics right before surgical operations. The aim of using plastinated models is to increase knowledge, understanding as well as imagination of the complex anatomical parts of the central nervous system. The plastinated anatomical teaching model of Medulla spinalis, Plexus brachialis, Plexus lumbosacralis and Cauda equina of goat displays a clear morphology that corresponds qualitatively to the actual cadaver specimens. Apparently healthy four goats (ten months age) from native breed were used. Goats were subjected to silicone S10 plastination technique. Prior to plastination, the goat was prepared by I/V injection of Xylazine Hcl (0.01mg/kg), cutting Arteria carotis communis for complete bleeding and injected via the latter artery with 10% formalized solution then immersed in the same solution for at least four weeks. Medulla spinalis and attached peripheral nerves, Plexus brachialis, Plexus lumbosacral and Cauda equina were dissected. The present study provided an enhancement for teaching neuroanatomy of the goat, especially Medulla spinalis, Nervi cervicales, Plexus brachialis, Nervi thoracici, Plexus lumbosacralis and Cauda equina. Understanding the anatomy of the nervous system is important not only for veterinary students but also for veterinary doctors while undertaking surgery on that plexuses and nerves.
