You have such facets on thoracic vertebrae. They are there to hold the ribs.
What else can I help you with?
What characteristics help you distinguish between the different types of vertebrae?
Cervical Vertebrae- has transverse foramen, and a bifid tip of spinous process Thoracic Vertebrae- Has coastal facets on the sides of the body Lumar Vertebrae- has no transverse foramen, no bifurcated tip, and no facets on the sides of the body
What articular surfaces are unique to the thoracic vertebra?
The surface that articulates with the ribs which is simply called the the "Demi-Facet" for the head of the rib. There is also a part on the transverse process of the thoracic vertebrae which acts as a block to prevent the rib from moving posteriorly.
Articular facets on the transverse processes are characteristics of vertebrae?
Yes, articular facets are small joints found on the transverse processes of thoracic vertebrae which articulate with the ribs. They contribute to the stability and articulation of the vertebral column, allowing for movements such as rotation and lateral flexion.
Why is there no transverse coastal facets on the last two thoracic vertebrae?
The simplest answer is because the 11th and 12th ribs (the last two) don't articulate with the transverse process of their corresponding vertebrae. Thus, transverse coastal facets are not needed.
What bone is an example of a facet?
Any of the vertebrae or lumbar all have facets on them, an example would be the articulate facet of vertebra
What are the two locations on a thoracic vertebra where the ribs articulate?
The two locations on a thoracic vertebra where the ribs articulate are the costal facets on the sides of the vertebral body and the transverse costal facets on the transverse processes. These articulations form the joints that connect the ribs to the thoracic vertebrae.
How many cervical thoracic and lumbar vertebrae are there?
Absolutely! They have features unique to the region they are found in, relating to structure and therefore function. Typical cervical vertebrae (C3-C6) usually have bifid spinous processes which point slightly inferiorly. The spinous processes on lumbar vertebrae are oblong in shape and point directly posteriorly. The articular facets of cervical vertebrae face superior-inferiorly, whereas lumbar articular facets face medial-laterally. Cervical vertebrae have transverse foramen on right and left(containing the vertebral arteries), lumbar have none. They have mamillary processes on their superior articular processes. The bodies of lumbar vertebra are larger and thicker than cervical vertebrae, though they are oval/kidney shaped shaped in both regions. The transverse processes of lumbar vertebrae are much longer, for muscle attachment. Cervical vertebrae have anterior and posterior tubercles extending from their transverse processes. The pedicles of lumbar vertebrae are slightly longer and more defined than those of cervical vertebrae. I think that covers everything, let me know if you think of anything else!
How are thoracic 11 and 12 different from the other vertebrae?
Unlike all other thoracic vertebrae, 11th and 12th thoracic vertebrae lack articulation surfaces (for tubercle of ribs) on their transverse processes. The articulation facets (for head of rib) on the body of 11th and 12th thoracic vertebrae are large.
What type of vertebrae has coastal facets?
These facets are associated with ribs which involve the thoracic vertebrae.
What provides an articulation point for the ribs?
transverse costal facets
The ribs are attached posteriorly to the what?
The ribs are attached posteriorly to the thoracic vertebrae of the spine through their articulation with the costal facets located on the bodies and transverse processes of the vertebrae. This connection allows for rib movement during breathing and provides structural support for the rib cage.
How can you distinguish a lumbar vertebra from a cervical vertebra?
the nerve cord is enclosed while a invertabrae nerve is opened
