so your back can be flexile
No, cartilage is like what the tip of your nose is composed of. It is also between the bones of your spine.
If you mean as in the cartilage between the bones in the spine - it's 'disc'
Answer to the riddle: A book. Geographic answer: A mountain Range. Science answer: Sharks. (Instead of bones, sharks have a spine and cartilage)
The vertebral column,also called spinal column, spine, or backbone, in vertebrate animals is the flexible column extending from neck to tail, made of a series of bones, the vertebrae. Also ligaments which hold bones to bones are present. Vertebral disks made of fibrocartilage are found between the vertebral bones.
The reason there are discs of cartilage between the bones in the vertebral column is because it is to cushion the vertebrae from grinding against each other, which is what happens when arthritis/age sets in, causing the discs of cartilage to erode and letting the vertebrae grind against each other/crush the spinal cord, causing pain and/or paralysis
invertebrates don't have a spine, and lack most bones. They are mainly made of cartilage.
One vertebrate that lacks a bony spine is the shark. Many different types of shark have cartilage instead of bones.
The spine, also known as the vertebral column or spinal column, is a column of 26 bones in an adult body – 24 separate vertebrae interspaced with cartilage, and then additionally the sacrum and coccyx.
your spine has controls the pressure between your bones so it doesnt't smash up together and also your muscles help by filling in the space between the bones.
Intervertebral discs are the fibrous, elastic tissue that lie between each of the bones in the spine. They function as shock absorbers.
when you get older, the cartilage in between your spine slowly goes away and you become shorter.
