During SBS flexion, the fingers on the sphenoid move which directions?

Explanation:
During SBS flexion, the sphenoid moves inferiorly and anteriorly relative to the occiput. Because cranial bones move in reciprocal directions at the sphenobasilar junction, the occiput moves superiorly and posteriorly. So the sphenoid’s surface is felt moving downward and forward by the treating hands. In contrast, during extension the sphenoid moves posteriorly and superiorly.
