What happens to the biceps and triceps as you raise the forearm?
when you bend your arm, your biceps contract, or tighten, and your triceps retract, or loosen. When you straighten your arm in a relaxed position, your triceps contract, and your biceps retract.
Do the tendons work with others to raise and lower the forearm?
Yes, tendons work in conjunction with muscles to raise and lower the forearm. When a muscle contracts, it pulls on the tendon, which then exerts force on the bone to facilitate movement at the joint. For example, the biceps brachii tendon helps raise the forearm, while the triceps brachii tendon assists in lowering it. This coordinated action allows for smooth and controlled movements of the forearm.
How does the skeletal and muscular systems work together to raise and lower the forearm?
The biceps and triceps muscles work synergistically; the biceps muscles contracting concentrically and the triceps muscles contracting eccentrically when the forearm lifts, and it's the exact reverse when the forearm lowers.

What muscles are used in boxing on your arm?
Assuming a straight punch: Striking- Forearm flexors - to make a fist Triceps - to straighten the elbow joint (Front) Deltoid - to raise the arm (parallel to the ground) Pectoralis Major - to drive your fist through their face :) Retracting- Biceps - the opposite of Triceps, to bend the elbow Latissimus Dorsi - the opposite of Pectoralis Major, to pull your fist from their empty skull :) Your main focus should be on speed and accuracy. Pecs and triceps are going to give you the power in your punch. Train your deltoids for endurance, if you plan on going round after round.
