Which ability is common to all three types of muscle tissue?

• A. Contract
• B. Relax
• C. Expand
• D. Rejuvenate

Answer: (A)

All three types of muscle tissue—skeletal, cardiac, and smooth muscle—share the ability to contract. This contraction is essential for various bodily functions. Skeletal muscle enables voluntary movement and is responsible for locomotion and posture, cardiac muscle controls the involuntary rhythm of the heart, and smooth muscle facilitates various involuntary movements in organs such as the intestines and blood vessels. While relax and expand are related to muscle behavior, they are more specific actions that can follow contraction. Rejuvenate is not a common characteristic of muscle tissue, as it refers to the process of renewal rather than a fundamental functional ability.
