What is the inferior articular facet?
[TA] the articular surface of the inferior articular process of vertebrae, articulating with the superior articular facet of the vertebra below to form a zygapophysial joint. Synonym(s): facies articularis inferior vertebrae [TA]
What is an articular facet vs 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. The actual region of contact is called the articular facet.
What does articular facet mean?
Articular facet. a relatively small articular surface of a bone, especially a vertebra.
Where is the inferior articulating facet?
The facet joints in the lumbar region lie in the sagittal plane; the articulating facets are at right angles to the transverse plane and 45° to the frontal plane. The superior facets face medially, and the inferior facets face laterally.
What is a inferior articular process?
: a process of a vertebra that lies on each side of the neural arch and projects downward and articulates with a superior articular process of the next more caudal vertebra The inferior articular processes have vertical convex articular facets which face anterolaterally. — Gray’s Anatomy, 39th edition.
What does facet mean in anatomy?
(făs′ĭt) n. 1. Anatomy A small, smooth, flat surface, as on a bone or tooth.
What is the inferior articular process?
The inferior articular processes run downward and slightly laterally from the laminae. Their articular surfaces face ventrolaterally to the superior articular facets of the vertebrae below them. The articular plane is curvilinear.
What is articular process?
Medical Definition of articular process : either of two processes on each side of a vertebra that articulate with adjoining vertebrae: a : superior articular process. b : inferior articular process.
What does facet mean in medical terms?
A small flat surface
A small flat surface on a bone or tooth or other hard body. A facet may be natural, as on the arches of the vertebrae, or the result of wear.
What is a facet joint?
The facet joints are the connections between the bones of the spine. The nerve roots pass through these joints to go from the spinal cord to the arms, legs and other parts of the body. These joints also allow the spine to bend and twist, and they keep the back from slipping too far forward or twisting without limits.
What are costal facets?
A costal facet is a site of connection between a rib and a vertebra. The costal facets are located on the vertebrae that the rib articulates with. They are the superior costal facet, the inferior costal facet, and the transverse costal facet.
What do you mean by facets?
Definition of facet 1 : any of the definable aspects that make up a subject (as of contemplation) or an object (as of consideration) Each facet of the problem requires careful attention. 2 : a small plane surface (as on a cut gem) — see brilliant illustration. 3 : the external corneal surface of an ommatidium.
What is a facet anatomy?
Facet joints are pairs of small joints in between the vertebrae in the back of the spine. These joints have opposing surfaces of cartilage, which limits friction between the bones. The joint is surrounded by a capsule filled with a small amount of synovial fluid.
What does facet joint mean?
Where are the facets in the spine?
Facet joints are hinge–like and link vertebrae together. They are located at the back of the spine (posterior). Facet joints are hinge–like and link vertebrae together.
What is a facet in anatomy?
Video Transcript. Facet joints are pairs of small joints in between the vertebrae in the back of the spine. These joints have opposing surfaces of cartilage, which limits friction between the bones.
What is a facet and where is it found?
Small joints located between and behind adjacent vertebrae. There are two facet joints at each level of the vertebral column, providing stability to the spinal column while allowing movement. They are found at every spinal level, except at the top level of the cervical spine.
What is an example of a facet?
The definition of a facet is a small, polished surface of a cut gem or a side or aspect of something. An example of facet is the side of an emerald. An example of facet is one of the causes of a war. One of numerous aspects, as of a subject.
