Question

With age, muscles can become weaker. This is due to __________.

Answer 1

The answer is letter C.

As we age the connection of our motor nerves to our muscle fibers tend to deteriorate. When this happens we tend to lose our balance and coordination as well as our overall muscular strength and endurance through time. This explains why we cannot perform some activities that we do when we were younger when we turn into adults. The brain is already having a hard time to recruit the necessary stimulus to be sent to the muscle fibers to perform necessary actions. This is why the human body is always compared to a ticking clock where any moment it could just give up because of its deteriorating nature.
