What is a sarcomere?

  1. A type of muscle tissue

  2. A muscle contraction disorder

  3. The basic unit of muscle contraction

  4. A neurological condition

The correct answer is: The basic unit of muscle contraction

A sarcomere is the basic unit of muscle contraction. It is the functional unit of skeletal muscle and is composed of overlapping filaments of actin and myosin. These filaments slide past each other during muscle contraction, resulting in the shortening of the sarcomere and the contraction of the muscle. Option A is incorrect because muscle tissue is a broad term that encompasses many types of tissue, including cardiac and smooth muscle. Option B is incorrect because a sarcomere is not a muscle contraction disorder. Option D is incorrect because it is a neurological condition and not related to muscle contraction.
