what are the points of articulation between the vertebrae? course hero

What does the vertebrae articulate with?

Each vertebra has a facet on each side of the vertebral body, which articulates with the head of a rib. There is also a facet on each of the transverse processes which articulates with the tubercle of a rib. The number of thoracic vertebrae varies considerably across the species.

What type of joint is found between the vertebrae?

An intervertebral disc unites the bodies of adjacent vertebrae within the vertebral column. Each disc allows for limited movement between the vertebrae and thus functionally forms an amphiarthrosis type of joint.

What does the lumbar vertebrae articulate with?

The sacrum is the complex of five fused vertebra that articulates with the fifth lumbar vertebrae.

What joint is formed by the articulations between the superior articular processes of the atlas and the base of the skull?

atlanto-occipital jointThe atlanto-occipital joint is formed by the articulations between the superior articular processes of the atlas and the occipital condyles on the base of the skull. This articulation has a pronounced U-shaped curvature, oriented along the anterior-posterior axis.

How many joints are there between two vertebrae?

There are three intervertebral joints between each adjacent vertebra from the axis to the sacrum – one between the vertebral bodies and a pair between the facets of adjoining vertebral arches (zygapophysial joints, also called facet joints).

What does the thoracic vertebrae articulate with?

Each thoracic vertebra articulates with a pair of ribs. Each rib end articulates with demifacets above and below the discs to form synovial costovertebral joints as well as the thoracic transverse processes to form costotransverse joints.

What is an articular process?

The articular processes or zygapophyses (Greek ζυγον = "yoke" (because it links two vertebrae) + απο = "away" + φυσις = "process") of a vertebra are projections of the vertebra that serve the purpose of fitting with an adjacent vertebra.

What is superior articular process of vertebra?

A superior articular process extends or faces upward, and an inferior articular process faces or projects downward on each side of a vertebrae. The paired superior articular processes of one vertebra join with the corresponding paired inferior articular processes from the next higher vertebra.

What does the superior articular facet articulate with?

Superior articular facet (Facies articularis superior) is an oval-shaped, concave structure on the superior aspect of the lateral mass. It articulates with an occipital condyle on the underside skull.

Where is the articular pillar located on a cervical vertebra?

The articular pillar is that part of the vertebra that lies immediately posterior and medial to each transverse process.

What type of joint is present between your first and second vertebrae?

Atlas is the first cervical vertebrae and Axis is the second cervical vertebrae. Axis have a process called Odontoid process over which atlas rotates. The joint between the atlas and axis is called Pivot joint. It allows the head to turn from side to side.
