You are craking your fingers.
Cracking during bending is primarily due to i. Improper deoxidation of steel ii. Low Mn/S ratio iii. Low temperature rolling
basically,when you have bending suppose you take beam(I-section) and an axis along the beam now, 1.curl you fingers in the direction of bending 2.point the thumb perpendicular to your fingers 3.thumb would give you the flexural axis(bending axis)
Bending your fingers is a more likely reason that they are wrinkled.
Folding, bending, and cracking of the earth's crust due to plate movement can result in the formation of mountains, earthquakes, and volcanic activity. This process is known as tectonic activity and is responsible for shaping the Earth's surface over millions of years.
I can bend my thumb back all the way until it breaks and feels even better after doing such been able to do this for year and been to doctors for explaination only met one other persons able to do aswell
it feel's so hard
The nerves in your thumb are located in the soft tissue and bone structure of your thumb. They run through the muscles, tendons, and ligaments in your thumb, allowing you to feel sensations and control movement in your thumb.
You can actually feel your own heartbeat in your thumb. You wouldnt get a correct pulse if you feel your heartbeat on the patient
Your thumb also has a pulse so you could be counting your own pulse beats per minute.
Mine is the same way, although I don't have the shoulder throbbing. My thumb cracks when I bend it, while pushing it against my index finger. In the morning or when I haven't used it much, it cracks just from bending it. If you figure this out, I'd be a happy guy, too! hahaha that's so funnie because my thumb cracks every time i bend it and i tryed putting it on my index finger and that made it crack tooo its annnoying
