What is the function of inferior articular process?
The inferior articular processes are flat and face downward to join with the superior articular processes of the C2 vertebra. The second cervical (C2) vertebra is called the axis, because it serves as the axis for rotation when turning the head toward the right or left.
What is Zygapophyses joint?
Zygapophyseal joints are the only synovial joints in the spine, with hyaline cartilage overlying subchondral bone, a synovial membrane and a joint capsule; they comprise the postero-lateral articulation between vertebral levels (Figure 1). The joint space has a potential capacity of 1 to 2 ml.
What is the function of spinous process?
The spinous processes throughout the spine function as a series of levers both for muscles of posture and for muscles of active movement (Standring et al., 2008). Most of the muscles that attach to the spinous processes act to extend the vertebral column.
What is the purpose of the superior inferior articular facets?
Each vertebra has two sets of facet joints. The superior articular facet faces upward and works like a hinge with the inferior articular facet (below). Like other joints in the body, each facet joint is surrounded by a capsule of connective tissue and produces synovial fluid to nourish and lubricate the joint.
What structures are Zygapophyses?
The zygapophyseal joints are true synovial joints that allow for motion of the vertebral spine while limiting excessive motion….Zygapophyseal Joint
- Radiofrequency.
- Ligament.
- Spinal Nerve.
- Sacroiliac Joint.
- Intervertebral Disk.
- Cervical Spine.
- Lumbar Spine.
- Vertebra.
What is the function of superior articular process of vertebra?
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.
Which joint is found between Zygapophyses of adjacent vertebrae?
Gliding joints
Gliding joints occur between the carpal bones, between the tarsal bones and those between the articular processes (zygapophyses) of successive vertebrae. So, the correct answer is ‘Gliding joint- Between zygapophyses of successive vertebrae’.
What is the function of the spinous and transverse process?
The spinous process serves to attach muscles and ligaments. The two transverse processes, one on each side of the vertebral body, project laterally from either side at the point where the lamina joins the pedicle, between the superior and inferior articular processes.
What is the function of the spinous process of each vertebra?
Spinous process is a bony projection off the posterior (back) of each vertebra. The spinous process protrudes where the laminae of the vertebral arch join and provides the point of attachment for muscles and ligaments of the spine.
What is the function of the costal facets on thoracic vertebrae?
The body also has small, smooth, and somewhat concave costal facets for the attachment of the ribs. Ribs are generally inserted between two vertebrae, such that each vertebra contributes to articulating with half of the articular surface.
What is the function of articular processes?
What is the purpose of articular processes?
What structures are zygapophyses?
What is the function of Centrum in vertebrae?
The centrum is the main, weight-supporting body of a vertebra that is cushioned by the spinal disc. This oval-shaped region forms the front of each vertebra and functions as the base for the pedicles.
What is the function of the transverse process?
The transverse process projects laterally from the junction of the lamina and the pedicle on each side of the vertebrae. The transverse process serves as a point of attachment for muscles that help move the vertebrae as well as ligaments that stabilize the vertebral column.
What is the function of the spinous process of each vertebrae?
What is the function of the spinous and transverse process of the vertebrae?
Spinous and Transverse Processes On each vertebra, there are two transverse processes and one spinous process. The two transverse processes are located on either side of the ring, while the spinous process is located in the middle. These processes provide sites to which back muscles and ligaments attach.
What is the function of the spinous process of each vertebra quizlet?
What is the purpose of costal facets?
The superior costal facet joins the rib to the top of a vertebra. The transverse costal facet joins the rib to the transverse process of a vertebra, and the inferior costal facet joins the rib to the lower part of the vertebra. The joints formed are known as the costovertebral joints.
