A Jamaican lady was seen dancing with her neck and also twerking her waist alongside, but the unfortunate happened within a second. Do not watch the
video if you cannot withstand it. The body of the cervical vertebra (the bony part) is small relative to the vertebral foramen (the opening that accommodates the nerves of the spinal cord). The spinal cord is a long, thin bundle of nerves that extends from the brain and is enclosed and protected by the vertebral column.
Compared to the size of the cervical vertebrae, your head is fairly massive. It sits on top of the cervical spine like a fish bowl on the tip of a finger. Because of this arrangement, small muscles can produce significant effects by tipping the balance one way or another. And that is also the reason that multiple muscles and restraining ligaments guard the range of motion of your head, preventing it from going too far.
In your day-to day life you move your head in a very predictable pattern, which is also the safest. It is natural for your head to move in a linear fashion. Circling the head is NOT a natural movement for the neck. When you move the head in an artificial circular pattern, you override the protective mechanism that your body has in place.

Below are some potential risks associated with neck circles, but first let’s take a look at what the cervical vertebra looks like. Each one of us has seven. Because of its delicate nature, the spinal cord needs to be isolated from bumps and blows – the task accomplished by the vertebral structures and surrounding ligaments, tendons and muscles. In addition, the spinal cord needs to be protected from the surrounding bony wall of the vertebrae themselves. The bony spinal canal normally has more than enough room for the spinal cord, but sometimes it can become smaller/narrower (called spinal stenosis). When that happens the bony structures of the vertebra can compress or pinch the nerves, which will show up as weakness, numbness or pain in the neck itself or anywhere along the nerve’s pathway.
