How is a lateral SBS strain dysfunction named?

• A. Named for the direction of the basi-sphenoid relative to the basi-occiput.
• B. Named for the direction of the occiput relative to the sphenoid.
• C. Named for the side of the skull where the lateral bones separate.
• D. Named for the magnitude of strain.

Answer: (A)

In lateral SBS strains, the naming is based on the direction the basi-sphenoid moves relative to the basi-occiput. This means the strain is labeled by where the sphenoid ends up compared to the occiput, not the other way around or by how large the strain is or where the lateral bones separate. So if the sphenoid shifts to the left relative to the occiput, it’s a left lateral strain; if it shifts to the right, it’s a right lateral strain.
