What does the triceps muscle do when the bicep contracts and gets shorter?
When the biceps muscle contracts and shortens, it primarily flexes the elbow, bringing the forearm closer to the upper arm. In this action, the triceps muscle relaxes and lengthens to allow for smooth movement, acting as an antagonist to the biceps. This coordinated action helps maintain balance and control during arm movements.

Why does your muscle form a hump when your arm is bent?
A muscle can do one of two things: it can contract, or it can relax. If the muscle is connected by tendons to bones, it will then pull on those bones when it contracts, and it will stop pulling on them when it relaxes. The arrangement of bones and muscles in the human arm allows muscles to bend the arm, by contracting. Also, muscles work in pairs. One muscle bends the arm while another straightens it out again. A single muscle can only pull in one direction, so you need a combination of muscles to be able to move around in a useful manner.
Is arm muscle example of involuntary muscle?
