Question

Quizplus · Accepted Answer

Certain smooth muscle cells can divide to increase their numbers, which allows for growth and repair of organs and tissues.

Answer: C
 Smooth muscle lacks the ability to synthesize or secrete any connective tissue elements, while skeletal muscle is able to do so.

Note: Option B is incorrect because smooth muscle does not have well-developed T tubules, which are a feature of skeletal muscle. Option D is incorrect because smooth muscle can stretch more than skeletal muscle, allowing for greater elasticity.
