How it works

-When the actin and myosin contract in the muscles, the muscles shorten and the bones are pulled closer together.

-Muscles called flexors force your joints to bend

-Muscles called extensors cause your limbs to straighten

It's connections with other systems

-Smooth muscles that line to your digestive system

-Smooth muscles also surround your circulatory system

-Muscular system is close to the nervous system

-The neurons are connected to the cells in your muscles

What can go wrong?

-You can pull a muscle
-You can get a muscle cramp

-One of several muscular diseases in which a person's muscles gradually and irreversibly become worse, causing weakness and eventually complete disability
