The Thoracic Vertebrae have such features and are in the correct position to articulate with the ribs correctly (the cervical vertebra are too high to touch the ribs in the neck region, and the lumbar, sacral and coccyx are all too low to intersect the ribs!)
Thoracic Vertebrae
What else can I help you with?
A special feature present on the transverse process of cervical vertebrae?
The transverse processes of the cervical vertebrae are pierced by a "foramen transversarium" through which the vertebral artery passes. The transverse processes of the cervical vertebrae are pierced by a "foramen transversarium" through which the vertebral artery passes.
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 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!
What are the parts of the vertebrae and how many bones are located in each selection?
The vertebrae consist of the vertebral body, spinous process, transverse process, and articular processes. There are 33 vertebrae in total, including 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral vertebrae (fused into the sacrum), and 4 coccygeal vertebrae (fused into the coccyx).
Cervical vertebrae can be distinguished from other types by the?
- Transverse foramen (holes in the transverse processes through which travels the vertebral artery) - Uncinate processes (lip on the supero-lateral aspects of vertebral bodies)
What vertebrae has articular facets on the transverse processes?
You have such facets on thoracic vertebrae. They are there to hold the ribs.
What are two accessory processes of the lumbar vertebrae?
the transverse process and the articular process also spinous process
What is the articular vertebrae?
Articular vertebrae refer to the specific regions of the vertebral column that contain the articular processes, which are bony projections that form joints between adjacent vertebrae. These processes are crucial for stabilizing the spine and allowing for controlled movement, such as flexion, extension, and rotation. Each vertebra has two superior and two inferior articular processes that connect with neighboring vertebrae, contributing to the overall function of the spinal column.
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 are the hole called in transverse processes of cervical vertebrae?
The holes in the transverse processes of cervical vertebrae are called transverse foramina. These foramina are unique to the cervical vertebrae and allow for the passage of the vertebral arteries and veins, which supply blood to the brain. They play a crucial role in the vascular system of the head and neck.
How many processes does each vertebra have?
Each vertebra typically has several processes, including two transverse processes and one spinous process. Additionally, there are two superior articular processes and two inferior articular processes that help form joints with adjacent vertebrae. In total, a typical vertebra has five key processes, but the exact number can vary slightly depending on the specific type of vertebra (cervical, thoracic, lumbar, etc.).

What is the name of the two lateral processes on vertebrae?
The two lateral processes on vertebrae are called transverse processes. These bony projections extend from the sides of the vertebrae and serve as attachment points for muscles and ligaments, as well as articulating with ribs in the thoracic region.
What is the vertebral processes?
Vertebral processes are bony projections that extend from the vertebrae in the spine. They serve as attachment points for muscles and ligaments, and they play a role in the stability and movement of the vertebral column. There are several types of processes, including spinous processes, transverse processes, and articular processes, each with specific functions related to spinal biomechanics. These structures are essential for maintaining posture and facilitating movement in the back.
