Lesson 3: Muscle Structure and Function

Question 8 • PA Human Anatomy & Physiology A 2026-2027 WHITE IC

A patient with muscular dystrophy starts to receive stem cells that generate muscle tissue. Which is the best prediction of what will happen to the patient's muscle function?

Answer

Muscle function should decrease because the cells would produce muscle tissue.

Muscle function should increase because the cells would produce muscle tissue.

Muscle function should decrease because the cells would not produce muscle tissue.

Muscle function should increase because the cells would not produce muscle tissue.

Explanation

If the stem cells generate muscle tissue, they can replace or add to damaged muscle cells. That should help the muscles work better, so muscle function is predicted to increase. Choice B correctly links producing muscle tissue with improved function.
