It’s all fascinating! Welcome back friends from the US, the UK, Denmark, Canada, Hungary, Italy, and Ghana! 😉
Probably you know this or you don’t. It’s about your hands. Diane initiated the talk by wondering about how your hands work.
Grant and Matt answered her that your hands are like any other part of your body: they have bones, muscles, nerves, and blood. But Nina quickly clicked the keys on her laptop, then added: “Outchh! It’s very complicated! Oh! And the numbers are staggering, listen:”
“The fingers on ne hand are bent and stretched about 25 million times over the course of a lifetime. Our hands also have very sensitive “antennae” for receiving information from the environment: There are a total of 17,000 touch receptors and free nerve endings in the palm. These pick up sensations of pressure, movement and vibration, so it is with good reason that the sense of touch is often associated with the hand. The skin on our fingertips is especially sensitive to touch.”
It’ s just impossible to imagine the very complicated and sophisticated processes that take place in your hands when you move them doing anything, while not realizing at all the magic you have in your hands!
The Creator gave you the most captivating structure, and you don’t even think about it, you just use it. Do you think you should thank your Creator for all those compelling miracles that you were given for free!?
Your hands have a very delicate and complex structure. This gives muscles and joints in the hand a great range of movement and precision. The different forces are also distributed in the best possible way. Thanks to this structure, you can do a wide range of things with your hands, such as grip objects tightly and lift heavy weights, as well as guide a fine thread through the tiny eye of a needle.
How do hands move?
Fingers do not contain muscles. The muscles that move the finger joints are in the palm and forearm. The long tendons that deliver motion from the forearm muscles may be observed to move under the skin at the wrist and on the back of the hand.
The human hand is made up of a total of 27 individual bones: 8 carpal bones, 5 metacarpal bones and 14 “finger bones” (also called phalanges) are connected by joints and ligaments. About one quarter of all our body’s bones are found in our hands. The hand can be divided up into three different areas based on the joints:
- Carpus (wrist bones)
- Metacarpus
- Fingers
