Thoracic
These facets are associated with ribs which involve the thoracic vertebrae.
The T10 vertebrae is located in the middle of the back.
The processes that occur in the coastal plain region of Virginia refers to geologic processes. The answer is erosion and deposition.
lumbar
Vertebrae are categorized by where they are located. The top 7 are called cervical vertebrae (neck), the next 12 are thoracic vertebrae (chest), and the last 5 are lumbar vertebrae (back).
These facets are associated with ribs which involve the thoracic vertebrae.
You have such facets on thoracic vertebrae. They are there to hold the ribs.
Thoracic vertebrae are located in the chest.
The T10 vertebrae is located in the middle of the back.
The dens is located on the cerival vertebrae on C2, which is the second vertebrae on the cervial vertebrae.
The lumbar vertebrae, there are 5 lumbar vertebrae.
Coastal geology studies coastal processes which affect the geology in coastal regions. Some coastal processes are effects of hurricanes, incised valleys, river migration, sedimentation, barrier island systems, estuaries, deltas, etc.
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)
to form a vertebral foramen in which the spinal cord (ad protected) is located and for attachment to posterior muscles such as erector spinae, trapezius, iliacus...
those are the vertebrae in the area of your neck.
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.
headThe pedicle of the rib articulates with the transverse process of the thoracic vertebra.
