What does the transverse foramina provide a passageway for?
The transverse foramina of the cervical vertebrae provide a passageway by which the vertebral artery, vein and sympathetic nerves can pass. They extend from above their respective vertebrae, through the intervertebral foramen created by the joints at the articular processes.
What passes through the pterygopalatine fossa?
What passes through Pterygomaxillary fissure? The pterygomaxillary fissure transmits the posterior superior alveolar nerve, a branch of maxillary division of the trigeminal nerve from the pterygopalatine fossa to the infratemporal fossa. Terminal branches of the maxillary artery also enter the fissure.
What structure passes through each intervertebral foramen?

What structures pass through the intervertebral foramina?
intervertebral foramen: The foramen allows for the passage of the spinal nerve root, dorsal root ganglion, the spinal artery of the segmental artery, the communicating veins between the internal and external plexuses, recurrent meningeal (sinu-vertebral) nerves, and transforaminal ligaments. 37 Related Question Answers Found What is Neuroforamen?
What structure passes through the vertebral foramen?
the spinal cordfunction in vertebral column arch surround an opening, the vertebral foramen, through which the spinal cord passes.
What blood vessels go through the transverse foramen?
Blood Supply and Lymphatics The anterior spinal artery is formed by the vertebral arteries which originate from the first part of the subclavian artery. The vertebral arteries pass through the transverse foramen of C1 through C6 and through the foramen magnum to become the basilar artery.
What blood vessel passes through the transverse foramen of the cervical vertebrae?
The vertebral arteryThe vertebral artery enters a space within the vertebrae called the transverse foramen at C6 and exits this space at the C2 cervical vertebra, the second-highest vertebra at the top of your spine, just below the skull.
What travels through transverse foramen of C1?
the vertebral arteriesOnce they have passed through the transverse foramen of C1, the vertebral arteries travel across the posterior arch of C1 and through the suboccipital triangle before entering the foramen magnum. Inside the skull, the two vertebral arteries join to form the basilar artery at the base of the Pons.
How many transverse Foramens are there?
Typical cervical vertebrae have several features distinct from those typical of thoracic or lumbar vertebrae. The most notable distinction is the presence of one foramen, in each transverse process.
What passes through the sacral foramina?
sacral nervestransverse processes of the lower sacral vertebrae, on each side, are a series of four openings (sacral foramina); the sacral nerves and blood vessels pass through these openings.
What is the transverse process of the vertebrae?
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.
Which arteries are not part of the circle of Willis?
The middle cerebral arteries, supplying the brain, are not considered part of the circle of Willis.
What structure passes through the vertebral foramen?
These are the root of each spinal nerve, the spinal artery of the segmental artery, communicating veins between the internal and external plexuses, recurrent meningeal (sinu-vertebral) nerves, and transforaminal ligaments.
What is the transverse foramina?
The transverse foramina of the cervical vertebrae provide a passageway by which the vertebral artery, vein and sympathetic nerves can pass. They extend from above their respective vertebrae, through the intervertebral foramen created by the joints at the articular processes.
How many vertebrae are there in the neck?
The seven vertebrae of the neck are characterized by an opening in each transverse process known as a foramen transversarium. The upper six pairs of foramina transversaria transmit the vertebral artery.
What is the bifid spinous process?
A typical cervical vertebra has a small body, a bifid (Y-shaped) spinous process, and U-shaped transverse processes with a transverse foramen. Thoracic vertebrae also have articulation facets on the body and transverse processes for attachment of the ribs.
What are the structures that pass through the foramina of the skull?
Structures passing through foramina of skull. The internal surface of the cranial base can be divided into 3 cranial fossae, the anterior, middle, and posterior. The anterior and middle fossae are separated by the lesser wing of sphenoid bone, and the middle and posterior fossae are separated by petrous part of temporal bone.
What bone separates the anterior and posterior fossae?
The anterior and middle fossae are separated by the lesser wing of sphenoid bone, and the middle and posterior fossae are separated by petrous part of temporal bone. Various structures (nerves, arteries, veins) passing through various foramina of skull are listed below:
Where is the transverse foramen located?
Transverse foramen/ Foramen Transversarium is a gap on each of the transverse processes which contain the vertebral artery and vein and a sympathetic nerve plexus and it is only found in the cervical vertebrae. The spinal nerves and ganglia traverse the dorsal border of the artery along with segmental vessels.
Which vertebrae have no arteries?
Transverse process surrounds the transverse foramen on left and right sides. It also serves as a site of muscular attachments. Transverse foramen of C7 vertebra contains only vertebral veins, with no arteries.
Where do vertebral arteries originate?
The vertebral arteries originate via the first portion belonging to the subclavian artery. After the vertebral artery is produced via from the subclavian artery, it travels via the transverse foramina of cervical vertebrae C1 to C6. Transverse process surrounds the transverse foramen on left and right sides. It also serves as a site of muscular ...
Where are the spinal nerves located?
The spinal nerves and ganglia traverse the dorsal border of the artery along with segmental vessels. With the exception of the atlas, the anterior and posterior tubercles are located on both sides of the transverse foramen at each transverse process on the cervical vertebrae.
