Sphenobasilar junction and the SBJ logo Steve Haines - 26 February 2010 The red logo at the top of the page is from a picture of the sphenoid and occiput bones forming the sphenobasilar junction (SBJ). These bones form a large part of the base of the skull. The big hole you can see is where the spinal cord enters the cranial cavity. The SBJ is an almost mythical place in the history of cranial work. It is the organising fulcrum for all the movements of the cranial bones. It is an important midline organising centre for all the expressions of primary respiration. That means that the SBJ often compensates and holds patterns due to the experiences and conditional forces that the person has undergone. Being skillful in orienting to the SBJ is a key skill in cranial work. It took me many years to feel comfortable to make a clear contact at the SBJ. The clearest impression I notice these days is health is expressed as the sphenoid diving forward on inhale and a sense of anterior posterior space at the SBJ.
