Cranial sutures are conventionally understood to be immobile after fusion, preventing movement. According to Lee,[30] understanding arose in the mid-1900s and was misinterpreted from the work of authors hoping to correlate suture closure with the chronological age of a skull . Lees suggests there was no correlation between suture closure and chronological age ,most skulls demonstrated no suture closure at all . Lee cites many references giving evidence for mobility in human skulls,[30] and modern anatomy books suggest incomplete fusion of some sutures, for example: "Sutural ligaments may effect an almost immovable bond between large areas of bone... but such immobility cannot be effected at narrow edges of bones in the cranial vault," and: "When such sutures are tied by sutural ligament and periosteum, almost complete immobility results."[31]

It is usual in cranial textbooks to say that the motion of the skull is possible during flexion and extension because the sutures are mobile, especially the spenobasilar synchondrosis (SBS) - the junction between the base of the sphenoid and the occiput. Positional descriptions of cranial lesions traditionally relate to the relationship between the sphenoid and the occiput at this junction. An alternative theory to SBS motion taught in craniosacral training suggests that sutures are "lines of folding", like pre-folded marks on cardboard, rather than necessarily being fully open.[32]
