These facets are associated with ribs which involve the thoracic vertebrae.
The coastal processes are located on the thoracic vertebrae. These processes articulate with the ribs to form the thoracic cage, which protects the vital organs in the thoracic cavity.
The second vertebrae has a dens (meaning tooth) which sticks up into the ring made by the atlas (the first vertebra). The head can pivot with this type of joint. A person can nod the head "no".
The xiphoid process of the sternum, the coastal margin of the thoracic wall, ends of ribs XI and XII, ligaments that span across structures of the posterior abdominal wall; and lumbar vertebrae
The lower lumbar vertebrae are the most stress bearing vertebrae.
A typical horse has around 54 to 60 vertebrae in its spine. This includes 7 cervical vertebrae (neck), 18 thoracic vertebrae (chest), 6 lumbar vertebrae (lower back), 5 sacral vertebrae (pelvis), and 16-18 coccygeal vertebrae (tail). The exact number can vary slightly among individual horses.
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.
You have such facets on thoracic vertebrae. They are there to hold the ribs.
they have facets for attachment of ribs
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
Any of the vertebrae or lumbar all have facets on them, an example would be the articulate facet of vertebra
There are a total of 33 vertebrae in the vertebral column, if assuming 4 coccygeal vertebrae.The individual vertebrae, named according to region and position, from superior to inferior, are:Cervical: 7 vertebrae (C1-C7) C1 is known as "atlas" and supports the head, C2 is known as "axis"Possesses bifid spinous processes, which is absent in C1 and C7Small-bodiedThoracic: 12 vertebrae (T1-T12) Distinguished by the presence of coastal facets for the articulation of the heads of ribsBody is intermediate in size between the cervical and lumbar vertebraeLumbar: 5 vertebrae (L1-L5) Has a large bodyDoes not have coastal facets nor transverse process foraminaSacral: 5 (fused) vertebrae (S1-S5)Coccygeal: 4 (3-5) (fused) vertebrae (Tailbone)
Thoracic vertebrae are between the cervical vertebrae and the lumbar vertebrae. The ones farther down the spine are larger. They have facets on the sides of the bodies for articulation with the heads of the ribs.
spinous process, facets, and demifacets
Cervical vertebrae articulate at tiny facets that don't allow for much movement but when combined with all the vertebrae in conjunction you get a range of movements from rotation to flexion to circumduction.
The coastal processes are located on the thoracic vertebrae. These processes articulate with the ribs to form the thoracic cage, which protects the vital organs in the thoracic cavity.
The thoracic vertebra
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.
