Answer #1

Muscle tension

It is the force generated during isotonic and isometric muscle contraction. It is a force exerted on an object when a muscle is contracting

Muscles contraction

Shortening of the sarcomeres due to cross bridging of actin and myosin heads causes the muscle fibers to shorten known as muscle contraction.

Muscle contraction is the process of generating a muscle tension

Contraction can be isotonic or isometric

isotonic contraction: During contraction, Changes in the muscle length will generate tension which is remain constant.

isometric contraction: tension produced without changing muscle Strength

Muscle twitch

It is a single and brief muscle contraction in response to a single action potential (or single stimulus). This may last for fraction of seconds
