Cardiac Muscle
Where is it found?

Muscle Fatigue
What causes it?
Click to flip
Overuse & energy depletion
Muscle fatigue occurs when muscles lose their ability to contract efficiently due to lack of oxygen, buildup of lactic acid, or depletion of energy stores (ATP).

Muscle Pairs
How do muscles work together?
Click to flip
Antagonistic pairs
Muscles work in pairs - when one contracts, the other relaxes. For example, the biceps and triceps work together to bend and straighten the arm.

Muscle Health
How to maintain healthy muscles?

Exercise, diet & rest
Regular exercise strengthens muscles. A healthy diet with protein, vitamins, and minerals supports muscle function. Rest and hydration prevent fatigue and aid recovery.
