1. The exact location and extent of the fracture must be identified.
2. The broken limb should be straightened very carefully.
3. Broken parts cannot be pulled.
4. In case of fracture in the upper part of the body, the patient should lie down and in case of fracture in the lower part, the patient should be seated.
5. Keep the wound clean.
6. Ice can be applied.
7. Wear loose clothing to keep blood circulation normal.
8. The broken parts should be fixed with splints or splints.
9. Blood flow should be checked.
10. The fractured limb should be elevated 6-10 inches.
11. The patient should take painkillers.
12. Doctor’s advice should be taken.

1. The injured area swells.
2. Movement of the affected limb causes pain.
3. A pricking pain is felt in the injured area.
4. There is great pain.
5. Cannot lift slightly heavy objects.
6. Hands and feet become numb.
7. Changes in the shape of the joints of the hands or feet.
8. The patient may become unconscious.

If the fracture remains inside the flesh and does not come out, it is called a simple fracture. If the bone is bent, it is called a greenstick fracture. In this case, the broken part should be bandaged. However, surgery is not required. It heals within 8 weeks.

Fractures or fractures of any bones in the body due to various accidents or injuries are called fractures. Doctors express fractures by the FRX or Fx signal.
There are three types of fractures. namely-
1. Simple or closed fractures
2. Compound or free fractures
3. Complicated or pressure fractures

Liver is divided into three categories. namely-
1. First class lever: The lever which has the falcrum between the load and the ball is called the first class lever. The 1st vertebra of the spine joins with the human crown to form the first class liver. Due to this lever, the head can be rotated forward, backward, up and down.
2. Second Class Lever: The lever where the load is between the falcrum and the ball is called second class lever. Class 2 levers are formed when the heel is raised by resting on the toes. Because of this lever one can run fast.
3. Third class lever: The lever in which the ball is between the falcrum and the weight is called third class lever. 3rd class lever is formed when an object is lifted by hand. Due to this lever, more weight can be lifted with less force.

The components of the liver are four. namely-
1. Rods or bars
2. Falcrum or Pivot – Rods act on it
3. Load or object – It moves against the force
4. Ball – It provides the force in the movement of the rods.

The interaction between bone and muscle during arm or leg movement is called lever. The force used to move the bone is called the fulcrum. Muscles exert tension or force during skeletal movement. The point of the lever where the force is applied is called the effort arm and the point where the force is attenuated is called the resistance arm.

Muscles and bones are connected to each other by tendons. Hence the movement of any organ depends on the rhythmic activity of the musculoskeletal system. Bone and muscle coordination in the knee joint is described below.
1. Flexor Muscles: Hamstring muscles and gastrocnemius muscles are required to bend the knee joint backwards. The hamstring muscle consists of three muscles. Biceps femoris, semimembranosus and semitendinosus. These muscles arise from the ischium of the pelvis and attach to the tibia. Their contraction brings the femur and tibia closer together and creates a fold in the knee joint.
2. Extensor muscle: The gastrocnemius muscle is the main muscle of the ball of the foot or ankle. It arises from the condyle of the femur and is attached to the calcaneus or ankle bone by the Achilles tendon. Their contraction brings the femur and tibia closer together and the knee joint bends backwards.
Intermittent contraction of muscle in normal or resting state is called muscle tension. Muscles are attached to bones by tendons. Each organ requires two types of muscles to move. These two muscles together are called antagonistic muscles. During limb movement, one muscle contracts and the other muscle stretches. That is, when one muscle is shortened, the opposite muscle is lengthened. Two types of muscles are attached to the humerus of the arm. Biceps muscle and triceps muscle. When raising the arm, the biceps muscle contracts and the triceps muscle stretches. At this time, no shock is felt in the muscles. Again, the biceps muscle expands and the triceps muscle contracts when the arm is lowered. Even at this time, the muscles do not need any push. Only the muscles are tense.
Muscle contains actin and myosin proteins. These proteins extend from one end of the muscle to the other and can stretch the muscle. This means that the muscles are only stretched, but not pushed.

Tonocity is the intermittent contraction of muscle in normal or resting state. Muscles are attached to bones by tendons. Each organ requires two types of muscles to move. These two muscles together are called antagonistic muscles. During limb movement, one muscle contracts and the other muscle stretches. That is, when one muscle is shortened, the opposite muscle is lengthened. Two types of muscles are attached to the humerus of the arm. Biceps muscle and triceps muscle. When raising the arm, the biceps muscle contracts and the triceps muscle stretches. At this time, no shock is felt in the muscles. Again, the biceps muscle expands and the triceps muscle contracts when the arm is lowered. At this time, the muscles do not feel any pressure. Only the muscles are tense.
Muscle contains actin and myosin proteins. These proteins extend from one end of the muscle to the other and can stretch the muscle. This means that the muscles are only stretched, but not pushed.

Tonicity is the characteristic of muscle tension or contraction. There are two types of muscle tension. namely-
1. High muscle tension: If there is excess tension in the muscles during normal rest, it is called high muscle tension
2. Low muscle tension: If the muscle tension is less than required in a normal resting state, it is called low muscle tension
