What is the function of the intervertebral discs?

Video transcript

Hello everyone and welcome to today's video. So how do inter virtual disks function as shock absorbers? As answer choice A we have allowing bending of the spine B allowing twisting of the spine C sending of information to the brain D helping to distribute forces evenly along the spine. So these inter virtual disk have two main functions, spinal flexibility and shock absorption. So they contribute to spinal flexibility by allowing the spine to bend and twist. However, they also work in shock absorption and they do so by helping distribute forces evenly. For example, when we jump or when we run, this is going to exert a force on our spine. If we don't have some type of shock absorption, this is going to damage our spine. So these inter virtual desk are going to basically help distribute this force evenly along the spine to prevent no concentration of these force in any specific area which could damage us. And therefore answer choice D helping to distribute forces evenly along the spine is going to be the correct answer for this question. I really hope this helped you and I hope to see you on the next video.
