What is muscular system?

Every single movement your body makes is produced by the muscular system. Muscles are layers of hardworking tissue that shape the body, keep it upright, and move it around.

Muscle tissue is made of long cells called fibres, which use energy to contract, or shorten, pulling different parts of the body into position. Movements are controlled by nerve signals from the brain. Sometimes you move your muscles consciously, such as when you sit down, or turn to look at something. But other muscle movements, such as your heartbeat, or when you blink your eyes, hapopen without you thinking about them.

There are three distinct types of muscles: skeletal muscles, cardiac or heart muscles, and smooth (non-striated) muscles. Muscles provide strength, balance, posture, movement and heat for the body to keep warm.
