Every time you move, sit in a chair or hug your child, using your bones, muscles, and joints. Without these necessary parts, we would not be able to stand, walk, run, or even sit down.

Bones and deeds

From our head to our toes, the bones- provide support to our body and help shape our body. The skull protects the brain and creates the image of our face. The spinal cord, the way to the language of the mind and body, protects the spinal cord, or spinal cord.

Despite the light, the bones are strong enough to support our overall weight.

Human bones have 26 bones, which begin to grow before birth. When the bones- begin to form, they are- formed by cartilage, but within a few weeks, they begin to have ossification. Ossification is when the cartilage is- replaced by a solid deposit of calcium phosphate and stretched collagen, the two most necessary components of bone. It took 20 years for this process to end.

The bones of children and adolescents are smaller than those adults and have "growing areas" called growth plates. These plates contain columns that increase the size of the cartilage cells that grow in length and then turn into solid bones. These size plates are easy to see on X-ray. Because girls grow older than boys, their growth plates change into hard bones at an early age.

Growing Bones

The bone-building continues throughout life as the body constantly regenerates and repairs living bone tissue. The bone has three types of cells osteoblasts, which form new bone and help- repair damaged osteocytes large- bone cells that help sustain the formation of newborns; and osteoclasts, which break bones and help carve and shape.

Osteoclasts are very active in children and adolescents, working on the bones as they develop during adulthood. They also play a necessary- role in the repair of cracks.

Bone is composed of calcium, phosphorus, sodium, and other minerals and protein collagen. Calcium is needed to dry the bones, which helps them to maintain body weight. Bones also store calcium and release it into the bloodstream when needed by other organs. The number of other vitamins and minerals you consume, especially vitamin D and calcium, directly affects how much calcium is- stored in the bones.

The soft bone marrow within most of- the bones is where most of the blood cells are- made. The bone marrow contains stem cells, which make up red blood cells and platelets, and other types of white blood cells. Red blood cells carry oxygen to the body's intestines, and platelets help with blood clotting when a person is cut or wound. White blood cells help fight disease.

Bones consist of two types of bone tissue:

1. Compact bone is the solid, hard, outer part of the bone. This type of bone is- made up of human bones. It looks like ivory and is quite strong. Holes and ducts run through it, carrying blood vessels and veins from the periosteum, which the outer bone membrane closes.

2. Cancellous bone, which looks like a sponge, is inside the compound bone. It is- made up of a mesh-like network of small pieces of bone called trabeculae. It is where red and white blood cells are- formed in the brain.

Bones are attached to other bones by long strings, called strings. Cartilage, elastic material, rubber, and our joints, support the bones and keep them in place for rubbing.

Muscles and What They Do

The bones do not work alone - they need help from muscles and joints. Muscles relax the joints, allowing us to move. They also help your body perform other activities so that you can grow and stay strong, such as chewing food and then digesting it in your stomach.

The human body has over 650 muscles, which make up about half the human body. They are attached to the bones by a tough, tendon-like Muscle that allows muscles to pull against the bones. If you rub your fingers, you can see the tendon on the back of your hand move as they do their job.

People have three different types of muscles:

1. Skeletal muscles are attached to the bone, especially in the legs, arms, abdomen, chest, neck, and face. Skeletal is said to be struck- because they are made of fibers with straight lines when viewed under a microscope. These muscles are attached to the bones, giving the body shape and contributing to the daily Movement (called voluntary muscles because you can control their Movement). They can move (slow down or hard) quickly and hardly - but they get tired- quickly and need rest between workouts.

2. Smooth or non-flexible, the muscle is also made of yarn, but this type of muscle looks less smooth. Too often, we cannot control our finite cells; instead, they are- controlled by an automatic neck system (hence the so-called misbehavior). Examples of muscles smooth the walls of the stomach and intestines, which help break down food and move it through the digestive system. Smooth muscle is- also found in the walls of the blood vessels, where it displaces the blood flow flowing through the blood vessels to help maintain BP. Sensitive nerves take longer to absorb wound tissue, but they can stay in place for longer because they are not easily damaged.

3. The cardiovascular system is found in the heart. The walls of the chambers of the heart are formed- by almost all of the muscle fibers. Cardiac muscle is a type of muscle disorder. The song, loud, powerful forces, the blood to flow out of the heart as it beats.

Our Nonstop Muscles

Even when we are in a good position, the muscles throughout the body are constantly moving. The seeds help the heartbeat, the heart rises and falls while breathing, and the blood vessels help control pressure and blood flow into the body. When we smile and speak, muscles help us- to Speak, and when we exercise, they help us stay healthy and in good health.

The movement of your muscles is coordinated and controlled by the brain and nervous system. Muscle freedom is- regulated by the depths of the brain and the spinal cord called the cerebral cortex. Voluntary health is- controlled by certain parts of the brain known as the cerebral cortex and cerebellum.

When you think of movement, the motor cortex sends an electrical signal through the spinal cord and across the neck to the muscles, causing them to become involved. The cortex motor is located on the right side of the brain moving the nerve to the left side of the body in rotation.

The cerebellum regulates muscle movement as directed by the motor cortex. Sensors in the muscles and joints send messages back through the external nerves to tell the cerebellum and other parts of the brain where the arm and leg are moving and how they are- positioned. If you want to raise your hand, your brain sends a message to the muscles in your hand, and you move it. When you run, Messages to the brain are more involved because most Muscles have to work in rhythm.

Muscles move body parts with coordination and also with relaxation. Muscles can pull bones, but they cannot pull- them back to their original position. As a result, they work on both sides of the flexors and extensors. You agree to bend the leg at the joint. Then, when the movement is complete, the flexor relaxes, and the contraction joints increase or straighten the leg at the same joint. For example, the biceps muscle in front of the upper arm is the flexor, and the triceps, behind the upper arm, is the extensor. When bending- your elbows, the biceps contract. Then the biceps relaxes, and the triceps contract to adjust the elbow.

Joints and What They Do

Joints occur when two bones meet. They make the skeleton flexible - without them, the movement would be impossible.

Joints allow our bodies to move in many directions. Some joints open and close like a hinge (like the knees and elbows), while others allow for a more flexible movement - shoulder or waist joint, for example, allows for back, front, side, and rotation movements.

Joints are arranged- by their type of movement. Unstable or fibrous, the joints do not move. As with the skull, for example, it is made up of bone marrow, which must be stable to protect the brain. Between the edges of these plates are the points, or joints, of the poisonous flesh. Combined gums also hold the teeth in the jaw.

The moving part, or cartilage, of the joints, moves slightly. It is associated with cartilage, like the spinal cord. One of the vertebrae in the spine moves about the upper and lower extremities together- this movement gives the spine flexibility.

The connective tissue, or synovial, joints move in many directions. The main joint of the body found in the waist, shoulders, elbows, knees, arms, and legs are- freely moved. They - filled with synovial fluid as a lubricant - make it easier for joints to move.

There are three main types of bondage that work primarily in volunteer travel:

1. Hinge joints allow for flexibility, as seen in the knees and elbows.

2. Pivot joints allow for rotation or twisting as the head moves from side to side.

3. Ball-and-socks joints allow for greater freedom of movement. Bone and shoulder have this type- of joint in which the rotation of a long nail penetrates the cavity of the other bone.

Problems With Bones, Muscles, and Joints

Strong as a bone, it can break. Muscles may- be- weakened, and joints (as well as joints, necks, and cartilage) may be prone to injury or disease.

Problems that can affect bones, muscles, and joints include:

• Arthritis. Arthritis is an inflammation of the joints, and people with it experience swelling, warmth, pain, and often difficulty walking. Although we often think of arthritis as a condition that affects only adults, arthritis can also occur in children and adolescents. Health problems including arthritis in children and adolescents include juvenile idiopathic arthritis (JIA, also known as Small rheumatoid arthritis, or JRA), lupus, Lyme disease, and septic arthritis (joint infection).

• Cracking. A fracture occurs when a bone is- broken; it can crack, crush, or break. After a fracture, new bone cells fill the gap and fix it at rest. Placing a solid implant, which keeps the bone in place until it heals, is the cure. If the fracture is severe, metal pins and plates can be inserted- for better stability as the bone heals.

• Muscle dystrophy. Muscular dystrophy is an inherited condition that affects the muscles, causing weakness and stiffness over time. The most common form in childhood is Duchenne muscular dystrophy, and it most commonly affects boys.

• Osgood-Schlatter syndrome (OSD). Osgood-Schlatter syndrome is an inflammation (pain and swelling) of the bone, cartilage, and tendon above the suture, where it sticks out from the knee. OSD usually strikes adolescent workers in the early stages of their development, which is about 2-year periods when they grow up much faster.

• Osteomyelitis. Osteomyelitis is a bone disease that is- usually caused- by Staphylococcus aureus bacteria, but other types of bacteria can cause it, too. In children and adolescents, osteomyelitis most commonly affects the long bones of the arms and legs. Osteomyelitis usually develops after an injury or trauma.

• Osteoporosis. In osteoporosis, the bone marrow becomes broken, thin, and recovered. The bones break easily, and the spine sometimes begins to collapse and fall. Although these conditions are more common in adults, children, and adolescents who are malnourished, the risk of developing a girl with epilepsy is threefold, which in some girls who play or sports can increase the risk of diet, amenorrhea (loss of a girl's mouth), and osteoporosis. Participating in sports where the value of appearance can put a girl at risk for a three-female athlete.

• Recurrent emotional distress (RSIs). RSIs are a group- of injuries that occur when excessive stress is- placed on a part- of the body, causing swelling (pain and swelling), muscle tension, or tissue damage. This stress usually results from the same repetitive movement from time to time. Playing tennis games that involve repetition can also lead to RSI. Children and young people who spend a lot of time playing instruments or video games are at risk of RSI. RSI is becoming more prevalent in children and adolescents because they spend more time than ever using computers.

• Scoliosis. Everyone's back is slightly bent; another amount- of bending is- required for people to move and move smoothly. But 3-5 out of 1,000 people have scoliosis, which makes its spine extremely flexible. It can be hereditary, so someone with scoliosis usually has family members with it.

• Suffering and crushing. Lines occur when the muscle or tendon is too tight. Sprains are for stretching or tearing part of a trap. Complications often occur when a person is taking part in a traumatic event, the muscles are not warming up properly, or the muscle is- not used in the event (such as a new sport or playing a well-known sport after a long break). Fractures the other hand, often result in injuries, such as twisting the ankle or knee. The most common spinal cord injury is the torn Achilles tendon, which connects the calf's heel. This tendon can rupture, but it can often be repaired- with surgery. Both strains and sprains are common in children and adolescents because they are active and still growing.

• Tendinitis. This common sports injury usually occurs after the overuse of muscles. The tendon and tendon sheath are burned, which can be painful. Relaxing the muscles and taking anti-inflammatory drugs can bring relief.
