What is the transverse foramen a passageway for?
The transverse processes of the cervical vertebrae are sharply curved (U-shaped) to allow for passage of the cervical spinal nerves. Each transverse process also has an opening called the transverse foramen. An important artery that supplies the brain ascends up the neck by passing through these openings.
What travels through the transverse foramen?
The vertebral artery and venous system pass through the transverse foramen, which is located medial to the tubercles of the transverse process and lateral to the vertebral body.
What does the transverse foramina contain?
According to our results, the transverse foramina of the seventh cervical vertebra almost universally contain vascular and nerve branches as well as fibrous and adipose tissue.
What passes through the transverse foramen of Atlas?
The transverse foramen allows the vertebral artery to penetrate the transverse process of atlas. The vertebral artery then winds dorsal and medially around the lateral mass in a grove on the posterior arch that cradles both the artery and the first cervical nerve.
What is the function of the transverse process?
The transverse process projects laterally from the junction of the lamina and the pedicle on each side of the vertebrae. The transverse process serves as a point of attachment for muscles that help move the vertebrae as well as ligaments that stabilize the vertebral column.
Does the atlas have a transverse foramen?
The transverse foramina also play an important protective role for the vertebral arteries and veins that provide vital blood flow to and from the brain. The bony tissue of the transverse processes of the atlas prevents these blood vessels from being compressed or damaged on their way through the neck.
What passes through vertebral foramen?
the spinal cord
function in vertebral column arch surround an opening, the vertebral foramen, through which the spinal cord passes. The centrums are separated by cartilaginous intervertebral disks, which help cushion shock in locomotion.
What goes through the transverse foramen and the vertebral foramen?
Transverse foramina are only present in the cervical vertebrae. These foramina allow the passage of the vertebral artery and vein. The vertebral arteries arise from the first part of the subclavian artery.
What does transverse process mean?
Transverse process is a small bony projection off the right and left side of each vertebrae. The two transverse processes of each vertebrae function as the site of attachment for muscles and ligaments of the spine as well as the point of articulation of the ribs (in the thoracic spine).
What is the transverse foramina for thoracic vertebra?
Foramina present in the transverse process of cervical vertebrae give passage to the vertebral artery-an important artery supplying the brain and spinal cord. Thoracic vertebrae typically bear facets on the body and the transverse processes for articulation with ribs.
