Humans possess a flexible upper limb. Their lower limbs are a bit more rigid. As we mentioned before, humans can be classified as bipedal. That means that our upper and lower limbs move in opposite directions. This flexibility also allows our lower limbs to bend and stretch during the walk.
Why do humans have large wrists and fingers?
While humans have very long and slender fingers, our hands are quite short compared to our wrists and fingers, which are around 9 cm and 2 cm, respectively. That is due to our very simple finger joints. Human fingers are also quite flexible. You need only imagine all the flexi-tendon muscles that make up our hands making up all the flexibility of our fingers.
How is it possible for humans to feel pleasure when eating hot food?
A couple of reasons. First, the food is warm and moist, which creates pleasant sensations. Second, our brains are very good at anticipating and understanding stimuli. This means our brains process the presence of the food as the food is near to us. In addition, our perception of foods varies greatly depending on the temperature level.
Why do humans yawn?
When you yawn, you release a small amount of air into your lungs. This release of air stimulates the sympathetic nervous system. This stimulates your digestive tract and aids you with removing excess material from the body. Additionally, we can also feel some discomfort during yawning due to our sympathetic nervous system (or sympathetic nervous system as it is officially known) and immune system.

What about the most important muscles of the human body?
The most important muscular muscle of the human is the elbow. This is where you hold your hands when you are eating food. When you eat food, it expands your intestines, which moves the food into the stomach. It is this expansion of the stomach that helps move the food out of the stomach and into the intestine.
The hand is the most used and important of the human body joints. It also plays a huge role in holding objects in the hands, such as our eyes, nose, fingers and eyes.
