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.
Where do ribs form a joint with the thoracic vertebrae?
headThe pedicle of the rib articulates with the transverse process of the thoracic vertebra.
What bones articulate with thoracic facets and demifacets?
The facets on the body articulate with next vertebra, while those on the transverse process articulate with the heads of ribs.
What surface articulates Inferior process of the superior thoracic vertebrae?
There is no inferior process on any vertebrae, thoracic or not. There is an inferior articular facet. The inferior articular facet would articulate with the superior articular facet of the vertebrae just superior to it.
How are thoracic vertebrae 11 and 12 different from all the other thoracic vertebrae?
The ribs attached to 11 and 12 do not connect to anything in the front of the body. They are said to be, "Floating".
What is the difference between the cervical vertebrae and thoracic vertebrae and lumbar vertebrae?
The Cervical vertebrae obtain: - Bifid (meaning double) spinous processes - Foramina transversarium for passage of nerves and vessels - The body is a more oval shape - Do not articuate with the ribs The Thoracic vertebrae obtain: - Spinous process (singular) - No foramina transversarium - The body is a small semi-circular shape - Articulate with the ribs -Have demifacets for articulation with the ribs The Lumbar vertebrae obtain: - Spinous process (singular) - No transverse processes - The body is a large circular shape - Does not articulate with the ribs - Demonstrates a "Scotty Dog" when positioned for a left/right anterior/posterior oblique radiograph.
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
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
What provides an articulation point for the ribs?
transverse costal facets
Typical type of vertebrae containing formula in the transverse process?
cervical 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.
How can you distinguish a lumbar vertebra from a cervical vertebra?
the nerve cord is enclosed while a invertabrae nerve is opened
