A muscular contraction that causes a muscle to shorten is called a concentric contraction. A concentric contraction is a type of isotonic contraction.

In biological theory, some biologists suspect the shortening of sacromeres causes aging.
A neurotransmitter that causes muscle movement is called Acetylcholine. Acetycholine acts as on both the central nervous system and the peripheral nervous system.
A cramp is a sudden over-shortening of a muscle. Cramps are involuntary and, often, severe. They can be extremely painful.
Muscle fatigue has a number of causes including ion imbalance within the muscle or nervous fatigue. And most importantly, from the accumulation of lactic acid in the muscle.
Atrophy
tourettes affect the nervous system because tourette syndrome is a condition that affects a person's central nervous system and causes tics.Also, tourette syndrome is a neurological condition, which means it's a condition of the nervous system
An eccentric contraction is one that causes a muscle to lengthen.
the connection between the two is like this. the nervous system sends the signal to the skeletal muscle to contract. This contraction causes the muscle to pull the bone, and the bone bends. This would mean that the movement of the skeleton is caused by nervous system which triggers the skeletal muscle to move the skeleton.
The shortening in them melts and causes them to spread.
The "movable" end of a muscle is called the insertion. The "immobile" end is called the origin. Shortening, or contraction, of a muscle causes the origin and insertion to become closer to one another.
