What are the names of the discs in your back?
Spinal Discs are in Between Each Vertebra Spinal discs are located in between each of the vertebral bodies along the back bone and may also be referred to as an intervertebral disc, spinal disc, or disk. Each disc is named according to which two vertebral bodies it lies between.
What are the disc numbers of the spine?
There are 23 discs in the human spine: 6 in the cervical region (neck), 12 in the thoracic region (middle back), and 5 in the lumbar region (lower back). IVDs allow the spine to be flexible without sacrificing a great deal of strength.
Which is the largest vertebrae in the human body?
lumbar vertebrae
The lumbar vertebrae are located between the ribcage and the pelvis and are the largest of the vertebrae. The pedicles are strong, as are the laminae, and the spinous process is thick and broad. The vertebral foramen is large and triangular.
What position puts least pressure on back?
When our back is in its ideal position, with us standing straight up or lying flat, we’re placing the least amount of pressure on the discs between vertebrae. When we sit down and cause the back to curve, we add close to 50 percent as much pressure to these discs as when we’re standing.
How many vertebral discs are there in the spine?
They act as a shock absorbers in the spine, positioned between each bony vertebra. They act as tough ligaments that hold the vertebrae of the spine together. They are cartilaginous joints that allow for slight mobility in the spine. There are a total of 23 vertebral discs in the spinal column.
What makes up one segment of the spine?
The disc and vertebra above and below the disc comprise one segment of the spine – usually called a spinal level or spinal segment. The L4 vertebra and L5 vertebra, along with the disc in between them, make up the L4-L5 segment Discs are always labeled for the vertebrae that they lie between,…
What are the functions of the spinal discs?
The discs throughout the spine have three primary functions: 1 They act as a shock absorbers in the spine, positioned between each bony vertebra. 2 They act as tough ligaments that hold the vertebrae of the spine together. 3 They are cartilaginous joints that allow for slight mobility in the spine.
What makes up the L4-L5 segment of the spine?
The L4 vertebra and L5 vertebra, along with the disc in between them, make up the L4-L5 segment. Discs are always labeled for the vertebrae that they lie between, and this is consistent throughout the length of the spine – for the cervical, thoracic and lumbar spine.
