Muscular System

Skeletal Muscle:

• Attached to bones (skeleton).

• Striated (has stripes).

Functions of the Muscular System:

1. Movement: Works with the skeletal system to allow the body to move.

2. Support: Helps maintain balance and posture.

3. Homeostasis: Regulates body temperature.

How Muscles Work:

• Muscles work in pairs:

  • One muscle contracts (shortens).

  • The other lengthens (relaxes) to cause movement.
