Over many years, morphological studies in the small intestinal mucosa in patients with cirrhosis have been reported [ 21].
In spite of many morphological and molecular studies, the family-level relationships among rodents and the location of the rodent root are still debated.
Many morphological and paleontological studies group Myriapoda with Hexapoda and Crustacea in a clade called Mandibulata (Scholz et al. 1998, Harzsch et al. 2005, but see Mayer and Whitington 2009a).
The phylogenetic relationships among asteroids remain extremely controversial in spite of many morphological and molecular studies that have been applied to this issue [ 26]. A. brevispinus is a very rare species and was once considered as only as a short-spined individual of A. planci [ 27].
Application of geophysical techniques has become more and more extensive and advanced in many geo-morphological studies since the early 2000s.
Moreover, because of the lack of detailed morphological studies in many groups, especially at the microscopic level, even in extant forms it may be difficult to determine whether or not some characters have evolved relatively independently (e.g., U-shaped gut or tentacles).
Although this conception is the foundation of many biomechanical, clinical, paleontological, and comparative morphological studies of trabecular bone in various species, attempts have not been made to contrast these data to a bone that could be considered a 'control' for simple/stereotypical bending.
This study demonstrated that the IC displays many morphological as well as dimensional variations.
In spite of the many positive features, a number of negative aspects are currently inherent to morphological studies of small animals using MRI.
Both species investigated in this study have a variable phenotype with regards to many morphological characters.
