What is the cartilage pads of the spine called?
The fibrocartilage cushions between the vertebrae in the column are named for their positions along the vertebral bodies, and are called the intervertebral disks. They have a thick outer ring of cartilage called the Annulus Fibrosus as well as a much softer center called the Nucleus Pulposus. This is not where the nerve tissue passes through, as some would suggest. Its purpose is to allow the joints to flex to some degree and to provide cushion for any axial compression that may occur. The only exception to the disk arrangement is that the first cervical vertebra does not have a body to articulate with the vertebra below it.The cartilage between the vertebrae of the spine forms the spinal discs, or intervertebral fibrocartilage. Each disc has a tough outer ring surrounding more flexible fibers that float in a protein gel. There are 23 discs in the entire spine.
Will vertebral venous plexus pass through foramen magnum?
Yes, the vertebral venous plexus can pass through the foramen magnum along with the spinal cord and its covering membranes. This network of veins can exit the skull through the foramen magnum, providing a pathway for blood flow between the brain and the vertebral column.
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)
How do spinal nerves exit the vertebral column?
Spinal nerves exit the vertebral column through small openings called intervertebral foramina located between adjacent vertebrae.
What runs through the center of the vertebral column?
The spinal cord runs through the center of the vertebral column, protected by the vertebral bones. It is a crucial part of the central nervous system, responsible for transmitting messages between the brain and the rest of the body. Injury to the spinal cord can result in serious neurological deficits.
What does herniation of a vertebral disc involve?
When a disc herniates, the jellylike substance pushes through and causes the harder outer ring (annulus fibrosus) to compress a nerve root in the spinal cord. Herniation of a vertebral disc can cause varying degrees of pain
What is HNP?
Herniated Nucleus Pulposus (HNP) - medical terminology for the following: Lumbar radiculopathy; Cervical radiculopathy; Herniated intervertebral disk; Prolapsed intervertebral disk; Slipped disk; Ruptured disk A herniated nucleus pulposus is a slipped disk along the spinal cord. The condition occurs when all or part of the soft center of a spinal disk is forced through a weakened part of the disk. definition comes from the Univ. of Maryland Medical Center web site.
What veins pass through the transverse vertebral foramina?
No veins pass through the the transverse foraminae. The vertebral arteries, however, pass through these spaces on their way to the brain.
Do sharks have notochords?
Sharks don't have notochords because they are vertebrates. All vertebrates go through an embryonic stage where a notochord is present, but then during development in the womb, this structure is replaced with a spine. The remnants of a notochord in these species can be found as the nucleus pulposus, a jelly-like center of intervertebral discs.
Part of the central nervous system extending from the brainstem through the vertebral canal?
The brain stem. The vertebral canal is called the foramen magnum.
What are the consequences of having a developmentally diminutive left vertebral artery?
Blood flows to the brain through the left vertebral artery. The consequences or risks of having a developmentally diminutive left vertebral artery is the risk of stroke.

What is the name of the hollow channel that runs through the vertebrae?
Vertebral foramen that the spinal cord runs through.
What is the function of vertebrarterial canal?
to allow the vertebral artery to pass through to the brain
What is the difference in articulation between the skull and the vertebral column of a rat and a human?
The articulations of the human skull and vertebral column consist of a series of amphiarthrodial joints between the vertebral bodies, and a series of diathrodial joints between the vertebral arches. The articulations of the rat skull and vertebral column consist of cervical vertebrae which have small, transverse processes containing a hole through which nerves and blood vessels pass.
