00:00 So now we will conclude or wrap up this lecture by discussing the way that we regenerate our muscle tissue. 00:09 So the interesting thing about skeletal muscle fibers is that they do not undergo mitosis. 00:17 Instead, skeletal muscle fibers undergo hypertrophy. 00:23 So the same muscle fibers that you had when you were born are the same muscle fibers that you have now, the only difference is they've gotten larger. 00:33 This increase in size is the definition of hypertrophy. 00:41 This is in contrast to hyperplasia. 00:45 Hyperplasia is what we normally think of when we think of things growing and that hyperplasia is an increase in the number of cells. 00:56 Some smooth muscles such as those in the uterus do have the ability to undergo hyperplasia. 01:03 And in this case, parasites are the stem cells that allow for this to happen.
The lecture Regeneration of Muscle Tissue (Nursing) by Jasmine Clark, PhD is from the course Musculoskeletal System – Physiology (Nursing).
Because skeletal muscle fibers cannot undergo mitosis, what is the process they use to grow?
