The eyelid is the fastest moving eyelid in the human body
The eyelids
Obicularis Occuli Muscle
Your eyelids.
It is the buttocks!!
The muscles know as Type IIx (also known as type IId), which is less dense in mitochondria and myoglobin. This is the fastest muscle type in humans. It can contract more quickly and with a greater amount of force than oxidative muscle, but can sustain only short, anaerobic bursts of activity before muscle contraction becomes painful (often incorrectly attributed to a build-up of lactic acid). N.B. in some books and articles this muscle in humans was, confusingly, called type IIB.The muscle with the fastest reaction time is the muscles used to close your eyelids. These are very close to the brain which is one reason why they are so quick. The other reason is if an object is seen coming towards the eye, it will close to prevent severe damage from occurring. Sometimes you will not even notice your eyes closing and then you are hit by something.
Perhaps you mean the buttocks. The buttocks is officially known as the gluteus maximus
No they are in the buttocks
The muscles are not normally small in the buttocks. They are required to move the legs which carries all of your body weight. The largest muscle in your buttocks is the gluteus maximus which is one of the strongest muscle in the body. Another major factor in the size of the buttocks is a fatty tissue covering the muscles. This gives the buttocks its characteristic rounded shape.
The muscle that moves the eyelids is called the orbicularis oculi muscle. It is responsible for closing the eyelids.
