What are thick bands that pull on bone as muscle contracts?
Thick bands that pull on bone as muscles contract are known as tendons. Tendons are strong, fibrous connective tissues that connect muscles to bones, allowing for the transfer of force generated by muscle contractions to facilitate movement. When a muscle contracts, it shortens and pulls on the tendon, which in turn pulls on the bone, resulting in joint movement.

Stretching exercises, proper hydration, and addressing any underlying issues can help alleviate foot cramps.
How does the supraspinatus muscle lift the arm?
The supraspinatus muscle, part of the rotator cuff, initiates arm abduction by stabilizing the shoulder joint and helping to lift the arm away from the body. It contracts to pull the humeral head into the glenoid cavity, allowing the arm to move upward. This action is crucial in the first 15 degrees of abduction, after which other muscles, primarily the deltoid, take over to continue lifting the arm.
What do you call the thick bands that pull on bones as a muscle contracts?

They contract to pull your rib cage both upward and outward when you inhale.
