The cranial base is the first part of the skull to develop and begins as mesenchyme condensations beneath the brain and around the developing sensory organs [12].
Lines xy, yz (yellow) and wy (blue) increase and angles wyz and xyz decrease c)
Cranial base shortening (black arrow); asymmetrical shortening results in an axial tilting of the brain.
This study supports the multifactorial nature of CM and syringomyelia and that this condition can not be explained by a simple defect in the development of a single skull bone; it is a more complex disorder involving
cranial base shortening, craniocervical junction abnormalities and other, as yet undetermined, factors not investigated in this study.
One can appreciate the increased height of the rostral cranial cavity (greater diameter of the occipital lobe circle) and decreased in size of angles 2 and 5 (yellow) in compensation for shortening of the entire
cranial base and increased proximity of the atlas to the occiput.
Consequently inadequacy of cartilage growth will result in a short
cranial base with increased angulation [16].
Line wy increase (blue), xy and yz shorten (yellow), angle xyz decreases e)
cranial base and caudal dorsoventral shortening.
To overcome this problem the authors used a circle extending from
the cranial base line (HAI) and encompassing the caudal aspect of the occipital lobe.
This is likely an apparent compensation for
cranial base shortening.
An explanation for this change could be
cranial base shortening and increased proximity of the atlas to the occiput.
The cranial base is angled at the level of the hypophyseal fossa where the rostral prechordal and caudal chordal parts meet.
When
the cranial base and the caudal part of the skull are shortened the circular model brain becomes increasing ellipsoid and there is greater axial tilt with an increase in height rostrally (white arrow).
A more acute Angle 5 was significant for both syringomyelia and CM and this finding suggests that these disorders in the dog are not just a consequence of a small volume caudal cranial fossa but shortening of the entire
cranial base.
This has led to the hypothesis that the condition may be due to insufficiency of the bone and / or craniosynostosis of the lambdoid (occipitoparietal) and
cranial base sutures.

cranial base, facial skeleton, mandible and dentition.

The skulls do share traits with some other fossils in east Asia dating from 600,000 to 100,000 years ago that also defy easy classification, says paleoanthropologist Rick Potts of the Smithsonian National Museum of Natural History in Washington, D.C. Those features include a broad
cranial base where the skull sits atop the spinal column and a low, flat plateau along the top of the skull.

Based on our recent development allowing the efficient and robust conversion of human pluripotent stem cells into affected spinal motor neurons and non - affected
cranial motor neurons, our objective is to deepen the mechanisms involved in the specific degeneration of spinal motor neurons in SMA as well as the mis communication of these neurons with their muscular target.
The changes in average
cranial capacity from Morton's seed -
based measurements to shot -
based measurements can not be reconstructed with any certainty, incorporate erroneous seed measurements made by Morton's assistant, yielded a broad range of changes (− 10 to +12 in3) hidden by Gould's mean, and are confounded by the shifts in sample composition (circa 50 %) between the two rounds of measurement.
Gould's claim that Morton had mismeasured crania
based on race derived from his comparison of Morton's seed -
based and lead shot —
based measurements, with different races experiencing different changes in their average
cranial capacity between the two methods [1].
In Morton's initial seed -
based 1839 study, «Caucasians» had the largest average
cranial capacity (87 in3) followed by «Mongolians [Asians]» (83 in3), «Malays [Island Southeast Asia]» (81 in3), «[Native] Americans» (80 in3), and «Ethiopians [Africans]» (78 in3)[8].
