MUSCLES AND MOVEMENT

A muscle is an organ that contracts to produce movement.
Our body has got many different muscles. There are two types:

• Muscles that are joined to bones by tendons. Together, these muscles form our musculature, which is responsible for movement. We can feel them tighten or harden under our skin when they contract.

• Muscles that are not joined to bones. These muscles produce different types of movement. For example, our heart muscles pump blood.
