There are two facet joints in each spinal motion segment and each facet joint is innervated by the recurrent meningeal nerves. What joint is between articular processes?įacet joints The facet joints, (or zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae. Continue to move your fingers in an inferior direction to assess and palpate the remaining transverse processes. While maintaining firm pressure, begin to move your fingers inferiorly approximately one finger-width to palpate the transverse processes of C2.

Which is the most prominent cervical vertebrae?Ĭ7 The spinous process (SP) of the seventh cervical vertebra (C7) is characterized as the most prominent, which makes it an anatomical landmark for the recognition of other SPs. These junctions form slightly moveable joints between the adjacent vertebrae. The paired superior articular processes of one vertebra join with the corresponding paired inferior articular processes from the next higher vertebra. How the articular processes of vertebrae are connected? With this type of injury, the other bone in the lower leg, the fibula, is frequently broken as well. What is a pillar fracture?Ī pilon fracture is a type of break that occurs at the bottom of the tibia (shinbone) and involves the weight-bearing surface of the ankle joint. Medical Definition of articular process : either of two processes on each side of a vertebra that articulate with adjoining vertebrae: a : superior articular process. The functional significance of the articular processes is obviously to limit rotation, which can take place in the lumbar segment of the vertebral column during any asymmetrical movement of the body. What is the function of articular process? Normal Anatomy The articular processes’ synovial intervertebral articulation complex is located dorsal to the vertebral canal and is composed of the caudal articular process of one vertebra, the joint space, and the cranial articular process of the following vertebra (Figures 52-12 through 52-14). How do you palpate the cervical articular pillar? Where are the articular process? The articular pillar is that part of the vertebra that lies immediately posterior and medial to each transverse process. These are the bony surfaces palpated just lateral to the spinous processes. In the cervical vertebral column, the articular processes collectively form the articular pillars.
