| Question | Answer |
|---|---|
| The Muscular System | A collection of organs that work together to move parts of the body. |
| Name the 3 types of Muscle | smooth muscle, cardiac muscle, skeletal muscle |
| Smooth Muscle | Found in the digestive tract and blood vessels. |
| Cardiac Muscle | Found in the heart. |
| Skeletal Muscle | Attached to bones to help you move; protects organs. |
| Voluntary Movement | A muscle action that you control. |
| Give examples of muscles with voluntary movement. | Skeletal muscle and Tendons |
| Tendons | Connective tissue that attached muscles to bones to produce movement. |
| Involuntary Movement | Muscle action that you cannot control. |
| Give examples of muscles with involuntary movement. | 1. Smooth Muscle 2. Cardiac muscle 3. Sometimes skeletal muscle- blinking |
| Give examples of smooth muscle. | 1. The digestive tract 2. blood vessels |
| Give an example of a cardiac muscle. | The heart |
| Why do skeletal muscles work in pairs? | Skeletal muscles move in pairs to produce smooth, controlled movements. |
| Flexor | A muscle that works to bend part of the body. |
| Give 2 examples of flexor muscles and their function. | Bicep- bends the arm Hamstring- bends the leg |
| Extensor | A muscle that works to straighten part of the body. |
| Give 2 examples of extensor muscles and their function. | Triceps- straighten the arm Quadriceps- straightens the leg |
| How do using your muscles help you? | 1. It keeps the muscles strong and healthy 2. It increases blood flow |
| Resistance Exercise | It develops size and strength of skeletal muscles. It requires muscle to overcome weight. |
| Give some examples of resistance exercise. | sit-ups, push-ups, lifting weights |
| Aerobic Exercise | It increases endurance of skeletal muscle and strengthens your heart. It is a steady, moderate, intensive activity |
| Give some examples of aerobic exercise. | jogging, cycling, swimming, aerobics |
