How do most people's left shoulders compare with their right shoulders?

Most people's left shoulder is wider and higher than their right shoulder.

The left-right asymmetry of the human body, some of which are formed during embryonic development, such as the asymmetry of organs in the chest and abdomen mentioned above. Some are gradually formed in long-term life. For example, most people are used to using their right hand, and the muscles of the right upper limb are relatively developed. Under long-term muscle traction, the spine and chest tend to bend to the right, while the waist tends to bend to the left, so the left shoulder tends to be wider and higher.

The function of lower limbs has a similar phenomenon. For example, most people are used to taking the first step with their left foot and kicking the ball with their right foot; When crossing your legs, you often support the ground with your left leg; When the legs are resting, one leg is often used as a support leg, and the knee joint is straight, and the other leg is used as a bracket, and the knee joint is slightly flexed, and then the rotation is exchanged.

The performance of human body's left-right asymmetry

The shoes we buy from the shoe store are often neither fat nor thin, neither too big nor too small, but the other foot doesn't fit well. Actually, it's not the shoes, but the size of our left and right feet is different. Not only the feet, but also our five senses, trunk, limbs and so on. At first glance, it is symmetrical, but it is actually asymmetrical.

For example, if you look at your face carefully with a mirror, you will find that our eyes are different in size; The thickness and height of eyebrows on both sides are also different; Most people's right hand is bigger than their left hand; The left shoulder is wider and higher than the right shoulder; The right leg is slightly longer than the left leg, and its weight and volume are also larger than the left leg. If you look at your face carefully, you will find left-right asymmetry.

It is found that the functions of the left and right hemispheres of the human brain are also asymmetric. Most people's left hemisphere is mainly responsible for language activities, while the right hemisphere is good at image recognition, music appreciation, space recognition and so on. There is only one organ such as heart, liver, gallbladder, spleen, stomach and pancreas in the abdominal cavity, but the shape is also asymmetric.
