What feature will provide assistance in maintaining the stability of the intervertebral foramen in they typical thoracics?
the costocentral joint or ribs
What is the rib-vertebral body combination at the intervertebral foramen for the ____ nerve? Let’s use T6 nerve.
The inferior costal demo-facet of T6 will joint with the superior articular surface of the head of the 7th rib.
The superior costal demo-facet of T7 will joint with the inferior articular surface of the head of the 7th rib.
What ligaments support the costocentral joint?
the costocentral stellate/radiate ligament and the costocentral interarticular or intra-articular ligament
What does the costocentral intra-articular ligament connect to?
the interarticular or intra-articular crest of the head of the rib and the intervertebral disc
What is the size relationship between the articulating surface of the head of the rib and the costal demi-facet surface?
the rib surface is greater than the costal demi-facet surface
