For this question, we can start by looking at our answer choices and relating these to each tissue type they correspond to, and which is most reasonable for the structure of the intervertebral discs of the spine.
00:19
So if we take a look at the structure of the spine, this consists of your vertebra, which of course have a spinous structure leading off of them.
00:30
And these are going to be sort of cushioned in between one another.
00:34
With these sort of jelly -like intervertebral discs.
00:45
And these are going to continue all the way down until they fuse when we meet our sacral and lumbar spines.
00:57
So if we consider the cellular components of each of the tissue types among our answer choices, we can first start with bone.
01:05
Bone is a sort of calcified tissue that has a very hard, very structured, lamular structure.
01:15
So this is going to be for a hard composition, typically what you'd find in your bones.
01:24
So it provides something to pull on when we're trying to create motion.
01:28
It's going to be hollow on the inside to give it a stronger rigidity.
01:35
And this is more for structure rather than for support.
01:40
So since our spinal intervertebral discs are more for compression, allowing for a flexibility.
01:48
Rather than a rigid structure, we know that bone is not going to compose these intervertebral disks.
01:56
If we consider the structure of muscle, these are going to be striated or unstriated, but these are going to perform a contractile force...
