Eight human fetuses of single pregnancy were studied. The ages of the fetuses were determined according to the foot length. Four fetuses were aged in the 2nd trimester and four fetuses were aged in the 3rd trimester of gestation. We used the dissector method to obtain the volume and numerical densities of the cardiac myocytes. We studied fifteen random dissector pairs for each specimen. For reasons of efficiency, one nucleus was considered one myocyte. We counted the number of the myocyte nuclei in the test-area appearing in an unbiased counting frame of 1600 microns 2 on the one-slice plane. We determined the numerical density of myocyte nuclei (Nv[nu] 1/mm3), the volume density of the myocyte nuclei (Vv[nu]%) and the average volume of the myocyte nuclei (V[nu]micron 3). Both Vv[nu] and Nv[nu] decreased from the second to the third trimesters of gestation and these differences are significant (p = 0.03 a reduction of more than 40%). However, the V[nu] remains practically unchangeable during the last two trimesters of gestation (p > 0.05). During this period the cardiac weight increases almost 800% and, of course, we can expect that the absolute number of the myocyte nuclei increase so much. So, the increasing number of myocytes with the simultaneous decreasing of the Nv[nu] might explained by the overall growth of the myocardium. This fact explains why the unitary volume of the myocyte nuclei remains practically unchangeable during this period.","PeriodicalId":75637,"journal":{"name":"Bulletin de l'Association des anatomistes","volume":"79 246","pages":"27-31"},"PeriodicalIF":0.0,"publicationDate":"1995-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19521539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The functional role of the Mamillary Processes (MP) is unknown. This study was carried out on 55 adult dried spines. The aims were 1) to record the interzygapophyseal joint angles. 2) to determine morphological and functional angle types. 3) to correlate the various types and the corresponding MP lengths. 4) to propose hypotheses about the MP role. There were 2 distinct morphotic types founded on 2 different populations of angles clearly visible on histograms at the T12 level and statistically detectable at the T11 and L1 levels. T11-T12-L1 realized an homogeneous anatomical unit with 2 separate groups depending on the zygapophyseal joint orientations. A functional classification was also possible depending on the location of the geometric axial center of rotation. The \"thoracic\" type which center was on vertebral body. 95% of T10 vertebrae and 88% of T11 vertebrae belonged to the \"thoracic\" type whereas 97% of L1 ans 98% of L2 belonged to the lumbar type. At the T12 level, we found 35% of \"thoracic\" type and 65% of \"lumbar\" type. Long MP were found on \"lumbar\" type vertebrae with little interzygapophyseal angles (p < 0.001). \"Anatomical\" types were not related to different MP lengths. On the contrary, the \"functional\" classification showed shorter MP on \"thoracic\" type vertebrae than on \"lumbar\" vertebrae (1.9 +/- 2.9 mm vs 4.5 +/- 3 mm, p < 0.03). A large interzygapophyseal angle is known to enhance the axial rotation of the thoraco-lumbar junction. We infer that MP also play a role in axial rotation.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":75637,"journal":{"name":"Bulletin de l'Association des anatomistes","volume":"79 245","pages":"13-20"},"PeriodicalIF":0.0,"publicationDate":"1995-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19516261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
