Transcript of Musculatory System
All animals except for the simplest invertebrates have muscles for movement.
The muscular system is mostly made of the muscles that allow your body to move and be flexable. Smooth Muscle: This muscle is found in internal and blood vessels. It helps move materials through the body.
Smooth muscle movement in your digestive system helps move food through your intestines. Cardiac Muscle: Cardiac muscle is the tissue that makes up your heart.
Your heart never gets tired like your skeletal muscle can.
The contractions of cardiac muscles push blood out of the heart and pump it around the body. Skeletal Muscle: Skeletal muscle is attached to your bones and allows you to move. You have control over your skeletal muscle.
Most skeletal muscles work in pairs around a joint.
One muscle in the pair, called a flexor, bends a joint.
The other muscle, the extensor, straightens the joint. Muscle Strain and Tears: A strain is a muscle or injury in which a muscle is overstretched or torn.
Muscular Dystrophy: It is a hereditary disease that causes skeletal muscle to become weaker over time.
Tendinitis: Tendons connect muscles to bones. Tendons can become inflamed or torn when muscles are overused. Muscle Strength: Resistance exercise helps improve muscle strength by building skeletal muscle and increasing muscle power. Muscle Endurance: Endurance exercise allow muscles to contract for a longer time without getting tired.
This can usually be done in 30 to 60 minutes a day. If a joint can move through a wide range of motions, it has good flexibility.
Flexibility refers to the full range of motion of a joint.
Stretching exercises help improve flexibility of a joint. The End By: Sergio Ramirez
