In recent years plastination has begun to revolutionize the way in which human and veterinary gross anatomy can be presented to students. The study reported here assessed the efficacy of plastinated organs as teaching resources in an innovative anatomy teaching/learning system. The main objective was to evaluate whether the use of plastinated organs improves the quality of teaching and learning of anatomy. For this purpose, we used an interdepartmental approach involving the departments of Veterinary Anatomy, Human Anatomy, Veterinary Surgery, and Education Development and Research Methods. The knowledge base of control and experimental student groups was examined before and after use of the fixed or plastinated resources, respectively, to gather information evaluating the effectiveness of these teaching resources. Significant differences (p < 0.001) between control and experimental groups of Human and Veterinary Anatomy were observed in the post-test results. The Veterinary Surgery students had the most positive opinion of the use of plastinated specimens. Using these data, we were able to quantitatively characterize the use of plastinated specimens as anatomy teaching resources. This analysis showed that all the plastinated resources available were heavily used and deemed useful by students. Although the properties of plastinated specimens accommodate student needs at various levels, traditional material should be used in conjunction with plastinated resources.

Detailed information is provided that may be used as a reference by equine veterinarians for the CT investigation of the equine TMJ and serve to assist them in the diagnosis of disorders of the TMJ and related structures (middle and inner ear). The study was performed at an immature stage and further studies of mature individuals are required in order to confirm that the clinical interpretation is not affected by changes occurring with age.

The purpose of this investigation was to define the anatomy of the cranioencephalic structures in horses using computed tomography (CT). Transverse images of two isolated equine cadaver heads were obtained using a Toshiba 600 HQ (third-generation equipment TCT). CT images were compared to corresponding frozen cross-sections of the cadaver head. Relevant anatomical structures were identified and labelled at each level. The resulting images provided excellent anatomic detail of the structures of the central nervous system and associated formations. Annotated CT images from this study are intended as a reference for clinical CT imaging studies of the equine head.

Resumen: Ordenar los procesos históricos en las culturas arqueológicas es una labor de gran complejidad cuando carecemos de las fechas en que se enmarcan tales procesos. Esa circunstancia ha representado un hándicap secular que dificulta el conocimiento de los primeros habitantes de Gran Canaria, acentuado por la escasez de referencias cronológicas que permitan comprender la ocupación de un territorio definido por su condición insular. Ello ha provocado la idea de una 'cultura plana' en la que se concitan numerosas expresiones del devenir de estas poblaciones, donde parece que todo existe y permanece, al menos en lo que a sus componentes esenciales se refiere. Con el propósito de superar esta limitación, en este trabajo se aborda el aspecto diacrónico de la práctica funeraria de los antiguos canarios, intentando a la vez su explicación en el marco de los procesos históricos que definen sus vidas. Se evalúan 104 dataciones provenientes de 25 enclaves funerarios repartidos por toda la isla, a partir de la elaboración de un modelo de estadística bayesiana. Los resultados revelan una evidente ordenación del fenómeno funerario, con intervalos de profundas transformaciones en un escenario social cambiante, relacionado con el proceso de ocupación de la isla y la evolución del modelo socioeconómico de este grupo humano. Asimismo, en el debate sobre las fechas de la primera arribada colonizadora, se establece el s. iii d. C. como punto de partida de la ocupación efectiva de la isla. Palabras clave: periodo prehispánico; Gran Canaria; cronología; fechas radiocarbónicas; estadística bayesiana.

Magnetic resonance images were obtained from two isolated horses' heads. Ten mm thick, T1-weighted images were taken with a 1.5 Tesla magnet and a body coil, and compared with the corresponding frozen cross-sections of the heads, relevant structures being identified and labelled at each level. The images should provide reference material for clinical magnetic imaging studies of horses' heads.

The remains in the LTB tomb were not a traditional nuclear family (father, mother and son/daughter) and it was probably a tomb where two women, one of them pregnant, were buried.
