Question

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

a. connections between nerves, which cause more pain and therefore less use
b. damage from everyday use and injuries that accumulate over time
c. disconnections between motor nerves and muscle fibers
d. difficulties that occur during muscle growth and repair

Answer 1

Option (C).

Step-by-step explanation:

Muscles are the important tissue of the body as they helps in the control of the body movements. Three different types of muscles are skeletal muscle, cardiac muscle and smooth muscle.

As the individual grows older the connection between the muscle fibers and the motor nerves get disconnected. This connection is important as it helps in the coordination of the body and sends the signal from the brain to the effector muscles. This disconnection result in the loss of coordination and body movements.

Thus, the correct answer is option (C).

Answer 2

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.
