Hello bloggers in today’s science we are learning about science.
We are gonna explain how to perform a handshake.
First step we have to extend our right handful vertically, connect web to web, and use your forearm muscles to shake two three times while engaging your grip strength.
The biceps and forearm contract to close fingers, while the thenar muscles contract for a firm grip. The flexor muscles relax, and the extrensor digitorum muscles on the back of the forearm contract to open the hand.
