My Topics to Research are:
1) 3 types of muscles
- Cardiac
- Smooth
- Skeletal
2) Major Organs
3) How they work
4) Major muscles
Muscular System
Did you know that muscle weighs more than fat? The muscular system is composed of over 600 muscles. Differences between each muscle are found by location, function, structure, and the way each muscle contracts. Muscles come in a variety of shapes and forms. They are found under the skin, over bones, so you can only see the outline.
3 Types of Muscles:
Cardiac
- looks straited/striped
- moves involuntarily
- allows heart to beat/pump
Smooth
- looks smooth
- moves involuntarily
- make up internal organs
- controls movement of inner body
Skeletal
- looks straited/striped
- moves voluntarily
- attached to bones to help movement
- contain multiple nuclei because of large size
Major Organs:
- skeletal muscles and smooth muscles throughout the body

Major Organs:
- skeletal muscles and smooth muscles throughout the body
How They Work:
- work in pairs
- one muscle shortens/contracts
- at same time one lengthens
- this pulls bone up causing movement
Major Muscles:
- Biceps-> found in front of arm
- Triceps-> found in back of arm
- Hamstrings-> found in back of thigh
- Quadriceps-> found in front of thigh
- Forearm-> found between the wrist and elbow
- Calves-> found in back of legs
- Gluteus Maximus-> butt muscles
- Abdominals-> muscles over stomach (Abs)
