Sentence examples for sacral configuration from inspiring English sources
This shows that the appearance of the sauropod-type of sacrum predated the marked increase in body size that characterizes the origins of sauropods, rejecting a causal explanation and evolutionary linkage between this sacral configuration and body size.
Alternative phylogenetic placements of Leonerasaurus as a basal anchisaurian imply a convergent acquisition of the sauropod-type sacrum in the new small-bodied taxon, also rejecting an evolutionary dependence of sacral configuration and body size in sauropodomorphs.
The clearest case is present in Plateosaurus, which has a unique sacral configuration among basal sauropodomorphs [56], [57], composed by the two primordial sacrals plus a caudosacral (S1+S2+CS; Figure 16).
The optimization of sacral configuration along the evolutionary history of basal Sauropodomorpha (Figure 16) shows that the four sacrals that previously diagnosed Sauropoda (or the clade of large bodied taxa composed by Melanorosaurus+Sauropoda) actually appeared earlier in the evolutionary history of the group, being diagnostic of a more inclusive clade.
Given that Plateosaurus is nested within sauropodomorphs with a DS+S1+S2 sacral configuration, the incorporation of a caudosacral and the deletion of a dorsosacral must be interpreted as autapomorphic transformations of the Plateosaurus lineage (an event explained as a possible homeotic frame-shift [75]).
LSTV associated with the fifth lumbar vertebra may show assimilation to the sacrum (sacralisation), and those affecting the first sacral vertebra may show transition to a lumbar configuration (lumbarisation) [1], causing misinterpretation as four or six lumbar vertebrae, respectively.
The configuration and size of the anterior sacral foramina may be altered, either due to insufficient reduction, or later due to callus formation during the bone-healing process.
There are only two DTI studies published in regard to LUT control in general: (1) a case report by Théaudin et al 22 studying spinal cord infarctions and clinical symptoms and (2) a prospective study by van der Jagt et al 23 investigating architectural configuration and microstructural properties of the sacral plexus.
Fearnley was born with lumbar sacral agenesis.
Ancient Near Eastern kingship was originally sacral.
