| Twelve adult male Wistar rats (220 g average weight) were divided in 3 experimental groups: GI -15. GII 30 and GIII 60 days, after mandibular molar extraction, with three experimental animals and one control per group. Qualitatively, ultrastructural changes of protein filaments from myofibrils of these muscles and ipsilateral to the extractions were observed. Ultrastructure asymmetry and disorganization of Z line and I band, in the experimental group GII, of Medial Pterigoid muscle (MPT) were observed. The temporomandibular dysfunction, stimulated by the unilateral extractions of mandibular molars in rats may lead to modifications in the Z line and I band, which showed to be sensitive to this dysfunction. Changes in the MPT muscle, probably related to... |

| Unclaimed corpses were for many years the supply of human material for the study of human anatomy. However, due to improved quality of life and technology, there has been the surround these. Faced with these circumstances, and the impossibility of total replacement of this material by others in training future professionals and the endless dissection technique, the Donation Voluntary Bodies for Anatomical Study is presented as an alternative to capture corpses or who wish to donate your body or part of it to research institutions and scientific study, without obtaining any pecuniary gain. Thus, the present study aimed to gather information about the knowledge and belief of the population of anatomists and freshmen, on the subject; obtain information on the... |
