| Abstract: | With the aim to further characterize the various regions of the nasal septum, the following measurements were made: In the thin anterior region and in the thick regions in the middle and posterior parts of the septum the quantitative relationships between cells and intercellular substance as well as the size of the cells were determined. The material used, included transverse and horizontal sections through the nasal septum of rabbits of ages of 1 day and 2, 4, 6, 8, 12 and 24 weeks. The results showed that in the thin anterior region the relationship between cells and intercellular substance remains constant, while in the two thick regions the amount of intercellular substance proportionately increases. In the thick regions, the cells are always larger than in the thin region. The rapid growth of the cells between the 4th and the 6th week coincides with a growth-spurt of the whole head. |
