What vertebral type contains the foramina in the transverse processes through which the vertebral arteries ascend to reach the brain?
A&P Ch6-8 Test rw
| Question | Answer |
|---|---|
| Cervical vertebra | contains foramina in the transverse processes which the vertebral arteries ascend to reach the brain |
| Coccyx | tail bone, fused vertebrae |
| Sacrum | composite bone, articulates with the hip bone laterally |
| Lumbar vertebra | massive vertebrae weight-sustaining |
What vertebrae contain transverse Foramina?
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. These transverse foramina encircle the vertebral arteries and veins.
What is the passageway for vertebral arteries?
Transverse foramen (Foramen transversarium) is a hole in the transverse process that serves as a passageway for the vertebral artery and vein.
What is the function of the intervertebral foramina?
The intervertebral foramen serves as the doorway between the spinal canal and periphery. It lies between the pedicles of neighboring vertebrae at all levels in the spine.
What does the first cervical vertebra C1 or Atlas lack quizlet?
The C1, uniquely, lacks a ventral body or centrum, as it is fused with that of the C2 vertebra at its own odontoid peg together with the odontoid process or dens of the C2 axis vertebra.
Does the atlas have a transverse foramen?
Each transverse process surrounds a tiny transverse foramen, a hole that provides room for the vertebral artery and vein to travel through the neck. The posterior arch extends posteriorly from the lateral masses and completes the ring of the atlas around the hollow vertebral foramen.
What is atlas vertebra?
atlas: the first cervical vertebra (C1), lying directly under the skull, through which the head articulates with the neck. The main connection to the vertebra below is a pivot around the odontoid process that is an upward projection of the body of the second cervical vertebra.
What goes through vertebral foramen?
The spinal cord passes through the vertebral foramina of the vertebrae: the collective vertebral foramina are referred to as the vertebral canal, or spinal canal. The anterior part of the vertebral foramen is formed from the posterior aspect of the vertebral body.
What are vertebral foramina?
The foramen is the bony hollow archway created by pedicles of adjacent vertebrae, creating a passageway through which all spinal nerve roots run. As a spinal nerve branches from the spinal cord, it exits through this opening and travels to organs, muscles and sensory structures of the body.
What passes through transverse Foramina?
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 is the function of the Atlas vertebrae?
The atlas is one of the two upper cervical vertebrae, also known as C1, which is the topmost vertebra of the spinal column. as its function is to support the globe of the head.
Where are the vertebral arteries located in the body?
The vertebral arteries work their way along both sides of the neck, connecting the subclavian arteries in the shoulder up to the cranium. Running through the gaps in the vertebrae (foramen), they access the posterior fossa, a small space at the base of the skull near the brainstem and cerebellum, as well as the occipital lobes of the brain.
Is the Atlas part of the cervical column?
At the cervical region the spinal column is further classified into an upper and lower cervical region. The atlas is one of the two upper cervical vertebrae, also known as C1, which is the topmost vertebra of the spinal column.
Where is the Atlas located in the body?
The atlas is one of the two upper cervical vertebrae, also known as C1, which is the topmost vertebra of the spinal column. It is the vertebra that is in contact with the occipital bone, a flat bone located at the back portion of the head.
