Age in mammals is usually estimated using weight and morphometric measurements of anatomical structures of growth, as well as by tooth wear.
Generally speaking, the range of the divergence of allometric patterns (9.9°-53.6°, Table 3) is similar to the results obtained from other geometric morphometric studies of different structures of the head skeleton in vertebrates [ 31, 33, 35, 59, 60], except for the premaxilla which is highly divergent (18.7°-101.3°).
The aim of this study was a complex morphometric evaluation of clinically important bone and mucosal structures of nasal cavity and examination of their dependence on age and sex in children up to 3 years of age.
In dipterans, the target structures of this analysis are the wings, because they have a two-dimensional structure; also, the veins cross to form points that are ideal for a morphometric comparison.
Correlation structure of morphometric properties of drainage systems and their controlling agents.
The conclusion is based on morphometric analyses and fine structure of the teeth using scanning electron micrographs that revealed such features as serration density, size and shape, and other characteristics of the examined specimens.
To highlight differences in the inflammatory responses induced in the lung tissue of vaccinated/challenged mice and vaccinated/unchallenged mice 30 days after infection, morphometric analysis of lymphoid structures was conducted by calculating the average size of individual follicles, or the entire area occupied by multiple follicles.
Bilateral symmetry is a ubiquitous concept, frequently used in geometric morphometric studies of biological structures.
This is a very important aspect to consider, since reproducibility is one of the pillars of morphometric evaluation of biologic structures.
No general framework exists, however, that extends the existing concepts and methods for studying morphometric variation of symmetric structures and biological asymmetry to all types of symmetry.
