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.
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.
What bones articulate with thoracic facets and demifacets?
The thoracic facets and demifacets articulate with the ribs, which form joints known as costovertebral joints. The facets on the thoracic vertebrae articulate with the heads of the ribs, while the demifacets articulate with the necks of the ribs.
How are thoracic vertebrae 11 and 12 different from all the other thoracic vertebrae?
Thoracic vertebrae 11 and 12 are unique because they only have one costal facet on each side for articulating with ribs (compared to two on each side in other thoracic vertebrae). They also lack a transverse costal facet on their transverse process.
What vertebrae has articular facets on the transverse processes?
You have such facets on thoracic vertebrae. They are there to hold the ribs.
What type of vertebrae has coastal facets?
These facets are associated with ribs which involve the thoracic vertebrae.
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

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.

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.
Thoracic vertebrae differ from the others in that?
they have facets for attachment of ribs
What bones articulate with thoracic facets and demifacets?
The thoracic facets and demifacets articulate with the ribs, which form joints known as costovertebral joints. The facets on the thoracic vertebrae articulate with the heads of the ribs, while the demifacets articulate with the necks of the ribs.

Thoracic vertebrae 11 and 12 are unique because they only have one costal facet on each side for articulating with ribs (compared to two on each side in other thoracic vertebrae). They also lack a transverse costal facet on their transverse process.
Bear facets for articulation with ribs form part of bony thoracic cage?
The facets on the transverse processes of thoracic vertebrae articulate with the tubercles of the ribs to form joints called costovertebral joints, which enable movement of the ribs during respiration. These articulations play a crucial role in the mechanics of breathing and provide structural support to the thoracic cage.
Why the body of the lumbar vertebra is larger than that of the thoracic vertebra and in the thoracic vertebra more than in the cervical vertebra?
The thoracic spine has twelve vertebral bodies. These structures have very little motion because they are firmly attached to the ribs and sternum (breastbone). Distinguished by the presence of coastal facets for the articulation of the heads of ribs. Body is intermediate in size between the cervical and lumbar vertebrae The lumbar spine has five vertebral bodies that extend from the lower thoracic spine (upper back) to the sacrum (bottom of the spine). The vertebral bodies of the lower back are the largest of the spine because they bear the majority of the body's weight. The paired facet joints on the back of the vertebral segments are aligned so that they allow flexion/extension but not a lot of rotation. Does not have coastal facets nor transverse process foramina
