Build Your Muscles From Early

The human body contains more than 630 muscles. Approximately 35-45% of body mass is muscle tissue. Muscles are long- lasting, self-healing and grow stronger with use. There are three unique kinds of muscle:

• Cardiac muscle, which is found only in your heart. It contracts involuntarily; it is automatically controlled by the nervous system.
• Smooth muscle is found in blood vessels, the digestive system, bladder, airways, and the uterus in a female. It also contracts involuntarily.
• Skeletal muscle is the kind we can see and feel. They attach to the skeleton and come in pairs; one muscle to move in one direction and another to move back the other way. Skeletal muscles contract voluntarily, you have to think about contracting them and the nervous system tells them to respond.

The combination of muscles and bones make up the musculoskeletal system. Together, the skeletal muscles work with bones to give the body its power and strength.

In most cases, skeletal muscle is attached to one end of a bone, stretches across a joint, and then attaches again to another bone. Tendons serve as connector pieces between muscle and bone; when a muscle is contracted, the tendon and bone move along with it.

Skeletal muscles come in a variety of sizes and shapes depending on their job. The muscles in your back, near the spine, are some of the biggest and most powerful. These muscles have the difficult job of keeping the body upright and providing the power to lift and push.

Your face also has plenty of muscles, over 30 as a matter of fact. Facial muscles don’t all attach directly to bone like those in the rest of the body. Many of them attach under the skin, which allows for more control. Contracting your facial muscles ever so slightly can create different looks like happiness, sadness, surprise, and frowning. Eye muscles are the busiest muscles in the body, moving more than 100,000 times a day!

The tongue is a muscle that’s attached only at one end. The tongue is made of a group of muscles that work together, allowing you to talk and help you chew food. It takes 72 different muscles interacting with one another to produce human speech.

The largest muscle in the body is in the buttocks and is called the gluteus maximus.

There are many problems which can affect muscles, causing pain and/or weakness. Some of the most common and least severe muscle disorders include:

• Sprain: A stretched or torn ligament. Wrist and ankle sprains are common and can be caused by falling or twisting.
• Strain: A stretched or torn muscle or tendon. Strains can happen suddenly or develop over time. Hamstring and back muscle strains are most common and are usually caused by twisting or pulling of the tissues. Many people suffer strains from playing sports.
• Muscle cramps: Sudden, involuntary contractions or spasms in the muscle, also called charley horse. Muscle cramps often occur after exercise or at night and can be caused by dehydration, strain or overuse of a muscle, lack of minerals in your diet, or insufficient blood supply to your muscles.
• Tendinitis: Inflammation of a tendon, usually occurring in the elbows, knees, shoulders, hips, heels or wrists. Certain diseases such as rheumatoid arthritis can cause tendinitis, but it is most commonly caused by injuries and overuse.

There are also many more serious muscle disorders such as cancers, diseases of the nerves that affect the muscles, and genetic diseases.

Use your muscles and strengthen them, you will need them to carry out everyday tasks and prevent you from falling and breaking bones as you grow older.
