    This study was made on twenty-one formalin fixed, adult skull left-half specimens. Each of the measurements was made using callipers accurate to 0.1 mm. The dissection of the temporal bone was begun with simple mastoidectomy and completed when the endosteum of the semicircular canals were opened. During the temporal bone dissection step by step, eleven different measurements have been made with small size callipers, and mean, median, range and standard deviations have been determined. The following set of correlations was found to be significant; I- The correlation between the orbitomeatal length and the distance from the most lateral point of the tympanomastoid suture to the facial canal (r=0.69, p<0.001). II - The correlation between the orbitomeatal length and the distance from the tympanic ring to the facial canal(r=0.49, p=0.011). III - The correlation between the distance from the most lateral point of the tympanomastoid suture to the facial canal and the distance from the tympanic ring to the facial canal (r=0.71, p<0.001).

    Wheat germ agglutinin conjugated horseradish peroxidase (WGA-HRP) injection into the midbrain periaqueductal gray (PAG) resulted in heavy accumulation of retrogradely labeled neurons in the lateral habenular nucleus (LHb) bilaterally. When the left femoral artery was persistently ligated for 2 h, the expression of Fos-like immunoreactivity (FOS-LI) was also found bilaterally in the LHb. In the present study, by combining the retrograde labeling method of injecting WGA-HRP into the PAG and the immunohistochemical staining of the FOS-LI neurons in the LHb induced by occlusion of the femoral artery, it was demonstrated that there are neurons containing both HRP labeling and FOS-LI. These neurons appeared to be located mainly in the medial part and posterior half of the LHb, and constitute about 24% of the total number of all labeled cells.

    In anatomy today, construction of the body is devoid of the water element, and the framework of the discipline is sectionalized (segmented, specialized, and divided), so that the body is not described in an integrated, harmonious manner. In this paper, the present authors selected the body, body water, and skin as objects of contemplation and deliberated on the history, significance, and resuscitation of anatomy.
    (1) Living things are dependent on water, and water is a vital component of the body. Therefore, greater consideration should be given to the presence of body water in morphological description of the body. (2) Since anatomy is sectionalized, understanding of the body is dwarfed and distorted. Whole anatomy, which described the body as a whole is the ideal style. (3) The body as a whole should always be placed in the center of anatomy. This should be the ultimate form of teaching anatomy.

    Immunohistochemistry revealed initial expression of the stage-specific glyocprotein, GP68, in various mesenchymal tissue substructures of mouse embryos. During the 11-15th days of gestation, GP68 was localized in the primitive meninges, chondroblasts and perichondrium of pre-cartilaginous vertebral bodies and ribs, connective tissue cells of the dermis, the epicardium and endocardium of the heart, the epimysium and perimysium of skeleton musclature, and the basement membranes of splanchnic organs. Double staining for laminin expression indicated coincidental expression in identical tissue substructures. However, laminin was expressed in days 10-18 embryos and the neonate. Therefore, GP68 is coincidentally expressed with laminin in mesenchymal tissues between the 11th and 15th day of gestation, and may play a role as a laminin-associated protein. In the light of these results, a hypothesis concerning the relationship between these two proteins and the mechanisms of non-integrin laminin-associated proteins during normal embryogenesis is discussed further.

    computer analysis was performed on the endomysium of the hyoid muscle in human fetuses, which ranged in gestational week from 12 to 32 weeks. During development of the human hyoid muscle a level of intramuscular connective tissue as reticular fibers displays a specific change in morphology. We examined quantitates and distributions of endomysium in human hyoid muscles from 12 to 32 weeks. The endomysium of the hyoid muscles formed complex structures, and volume rates increased from 20 weeks gestation. On the other hand, the cross sectional area (CSA)of muscle fibers had almost the same profile. The reticular fibers increased during development from 16 to 28 weeks gestation.

    We quantitatively examined the distribution of the proliferating cell nuclear antigen (PCNA), which is associated with cell division, and of components of the ECMs (collagen types I and III, tenascin and osteonectin) in the immature zones at three sites: palatine, inferior and vertical surface region of the fetal human maxilla as well as the maxillary sinus (MS) at 12,16,20,24, and 28 weeks gestation. The percentage of PCNA-positive cells was the highest at 16 weeks in the immature zones of maxilla. Tenascin and fibrillar collagens (collagen types I and III) were especially present in the cellular zone linked to the bone and cartilage matrices of the immature zones of the maxillary bone at 20-24 weeks gestation. The osteonectin was detected on the maxillary bone from 24 weeks. These distributions of ECMs revealed the specific and contrasting profiles of development in the human maxillary bone and might reflect the formation of paranasal sinus as MS.
