There is still a myelin sheath present - just in far lower amounts compared to the white ramus communicans.
The atlantoaxial ligament as the dorsal ramus emerges 3.
This muscle originates from the upper part of the inferior ramus of the pubis from where it runs downwards and laterally.
Shortly after a spinal nerve exits the intervertebral foramen, it branches into the dorsal ramus, ventral ramus, and rami communicantes.
Ventrally, the braincase is underlain by the posterior rami of the pterygoids.
The ascending rami were removed by cutting through the corpus just posterior to the area of the third molars.
On the facies medialis of the left ramus mandibulae, a suture is preserved that might represent the sutura dentalosymphysialis.
The poor condition of the fragment does not allow us to say precisely how it was separated from the rest of the ramus.
