If muscles are not properly fueled with the proteins and nutrients they need to be strong and health they will be more apt to tear, rip, and weaken.
A baby's neck muscles are not strong enough to support the weight of their head. If a baby's head and neck are not properly supported, what can happen is that there will be an injury to the neck and back.
The muscles will atrophy (shrink) if not used.
The muscles responsible for ensuring that organs function properly are called smooth muscles. These muscles are found in the walls of organs such as the stomach, intestines, and blood vessels, and help to regulate the movement and function of these organs.
for example when you eat a bologna sandwich on rye, the fulcrum in your arm levers the joints in your body. This causes there to be a friction between the two muscles, causing your elbow to properly bend.
Smoking can weaken the muscles of the diaphragm, making it harder for the diaphragm to contract and expand properly. This can lead to decreased lung function and difficulty breathing over time.

All muscles contract when functioning properly. That's all they know how to do.
