To answer the above question is, by my knowledge, incorrect; as far as I know I cannot turn my head "all the way around." Unless I was able to snap my head, neck and spine so as to turn in a full three hundred and sixty degrees and then immediately place it back to normal free from pain, death, and abnormal change in the physical characteristics of the area surrounding my head.
To answer the question that was probably meant to be asked: "Why is it that a human cannot turn their head a full three hundred sixty degrees?" I would answer that it is because of what is known as our natural anatomy. Through study, it would be completely simple to answer the exact reason as to why a human cannot perform the said action. It is obvious however, to conclude that it has to deal with the fixed position of our neck and the anatomy behind the rotation of the head.
you can't only owl's can do that it is something in there neck that helps them do that
no no
It is a social signal to others that you are finding something pleasant.
An ex physical education expert gives you this advice. Tell your parents and see your doctor.
The semicircular canals of the inner ear are sensory organs that provide the brain with information about head movement and position. They are filled with fluid that moves due to inertia when the head moves, triggering nerve endings. There are three so that movement can be sensed in all three spatial axes. You can turn your head, tilt it forward and backward, and side to side. Yaw, pitch, and roll, as with an airplane. Any one of these motions causes the fluid in one of the canals to move. If you spin around rapidly and suddenly stop you become dizzy because the fluid in your canals moves more rapidly than it usually does.
Being able to roll your tongue is dominant, not being able to is recessive. Therefore, if you can roll your tongue, you have either a homozygous dominant gene for being able to roll your tongue, or a heterozygous gene. If you cannot, then you have a homozygous recessive gene.
The stage of death when a person allows their eyes to roll back in their head and the eyes become fixed is clinical death or the end stage. This is the final stage of death.
Probably from the fact that when a person was executed by guillotine the head would roll around, even when landing in a basket.
Circle or a cylinder.
Bounce the ball off of the right circle and get it around the spiky guy into the bubble (you will have to die if you are rollong around beneath the bubble!)
The best roll for parkour is rolling over your shoulder with your head tucked in/to the side. You do not want to roll over your head.
No, it cannot. The reason for this is a circle is flat, but a sphere is a whole other story.
Fold it twice over each other then roll the other around it in a circle.

A hollow cylinder.
Your eyes can roll to the back of your head when you have a seizure - it is not the epilepsy medications that do this.
Because the sides are like a circle.
No.
