MUSCULO SKELETAL SYSTEM
As the name suggests, it is a system based on BONES and MUSCLES and its function is to help the body move. Movement refers to moving the body and moving from one place to another. Due to this system we are able to do our various tasks. You must have seen many such cases where the bone of the toe is broken in an accident and the person is unable to walk or the muscles are stiff due to running and the hand is not being raised. These are examples of this system being effective over time. There are more than 200 bones in the body that join together to form a complete structure. Where two bones meet each other is called a "joint." This system of bones and joints is called the SKELETAL SYSTEM.
Skull
The skull is made up of three thin bones. Which protects the mind. The structure of the mouth and jawbones are slightly different, which makes each person's face different It varies. Contains the spinal cord. On many small arms of the spine, the bones are placed on top of each other in such a way that it becomes a pillar. Hari is called Mehra (VENTEERA). The spine starts from the first part of the back of the large neck and goes down. It is responsible for giving the large body a specific shape, keeping the back straight and conducting the nerve pathways to different parts of the body. Each vertebra also has a hole through which the spinal cord passes. To keep the seals in place and to maintain the shape of the entire bone, there are protective bands around the bone called ligaments. The space between the two seals is called the disc (DISC). It is made of a thick material whose function is to protect the seals from friction and withstand any kind of shock. After Sometimes due to an accident, the disc (DISC) ruptures and protrudes outwards and starts putting pressure on the nerve fibers. Due to which severe pain is felt. Oftentimes this reason can also be knowledge.
Shoulder
And it is behind the side, in the upper part there are two bones in the right shoulder. There is one on the lower and left side, it is called Scapula. Another bone connected to it is called the clavicle, which is located slightly below the front of the neck on both sides. This bone goes between the shoulder and the chest bone. Shoulder blade is also called shoulder blade. While the other name of pencil bone is collar bone.
Bones of the arm
The arm has a large one in the upper part of the arm. It comes from the shin to the elbow, it is called humerus. From the elbow to the wrist there is a pair of two bones. One of them is called RADIUS and the ULNA.
Hand
There are eight small bullet-shaped bones in the lower part of the wrist. They are called carpals. The five bones below them are the bones of the palm called AMETA (CARPALS). After the heel bones come the finger bones which are called phalanxes. The thumb has two wholes while the other four fingers have three wholes.
Chest bone and first:
These bones form the rib cage. Ribs have twelve joints. Thus their total number is what they are. Twelve of which are on one side and twelve on the other side. If you feel with your hand, you will know that these ribs are connected to the spine at the back, ten of the twelve ribs at the front are the sternum ribs, while the eleventh and the twelfth rib are the major rib of the chest. remains free. These ribs are called floating ribs.
PELVIS
In the lower part of the back, there is a large bowl-shaped organ called the pelvis. Which supports the spine. And it reaches the legs. The pubis is actually made up of two bones. They are called PELVIC BONES. These bones are attached to the posterior part of the spinal cord (sacral joint) while on the finger side (PUBIC SYMPHYSIS).
Sacral Mehra: Leg . The leg has three parts
1. Thigh
2. Knee
3. Calf
In the upper part of the leg (thigh).
The biggest part of the body is called the thigh or pride. Badi is connected to the superior PELVIC (BONE) while the blue side is connected to the pelvis. The bone that forms the front of the knee is called the patella. It is a plate-shaped bone that is smaller in size and protects the knee joint. There is a large and a small one in the shank. The big one is called TIBIA and the small one is called FIBULA. The large bone forms part of the upper part of the pelvis. Both bones meet the ankle bones downwards. Foot (feet) - There are seven bones in the ankle part of the foot. These bones are soft inside but outside are tougher than They are called TARSALS. Immediately after them are the bones of the sole (META TARSALS) which form part of the middle of the toe. Finally, the soles of the feet.
PHALANGES
The thumb has two puris while the rest of the fingers have three Our feet on The part where two bones meet is called a joint. Two types of them
MOVEABLE JOINTS :: In these joints, free movement is possible. The bones that make up this joint can move freely back and forth and side to side.
IMMOVABLE JOINTS :- If two or more bones are joined in such a way that no movement is possible in them, then it is immovable.
The polytheists say Movable joints. Body parts are able to move due to these joints. Because of them we can eat our heads. Can bend the legs are Can spread hands. In short, movement in all organs is possible only because of these joints. When a joint is formed, the two bones are close to each other and there is a little distance between them. This space is filled with a liquid called synovial fluid. The whole joint is hidden from all sides by special types of knots. These fibers are called ligaments. These fibers not only keep the bones in a certain position but also help in movement. There are three types of moving joints. BALL AND SOCKET JOINT 2 Hinge-like joint -3- Chola joint -1 Ball and socket joint (BALL AND SOCKET JOINT). Can rotate, examples are the hip and arm joint.
Logitech , Balato, OPTIPLEX 700, hinge-like joints (INGE JOINT)
There are pits
The bones involved can move up and down and forward. Hours, said and Joints of fingers are examples of this.
PIVOT JOINT - This joint is in the neck and elbow. In it, a pivot joint can rotate on the bone.
GLIDING JOINTS
These are also examples of gliding joints which can move on top of each other along with the rotation of the water column. His At the same time, the bones found in the trunk also have such joints. Joule Ball Joule and Play Hull Immobilized joints: In these the bones are completely connected to each other and there is no room for any movement between them. Such joints are stronger than other types. Our head bones are an example of this. The cervical spine is made up of three bones that form immobile joints They meet each other with help. Dynamic joints also have more movement, but they also break down more The risk of diseases is also high. The middle membrane of the fontanelles (THE FONT ANELLES) in newborns - so the head in babies where they are rarely separated from each other. Instead, there are openings in the opening between them (FONT ANELLES) that can project to the distal end of this membrane and can expand. The real benefit of this feature is at the time of child birth. At the time of delivery, these bones contract and touch each other closely so that the baby can come out of the mother's womb comfortably. Similarly, after birth every If it is not obstructed, these bones will spread easily. This birth membrane of the head can be divided into two parts. The anterior fontanelle is called the anterior fontanelle and the posterior fontanel is called the posterior fontanelle.
MEMBRANE FONTENELLES
remain soft for a few months from the time of birth. After that, it ends and their place is taken by the big one. This membrane is shed within four months of birth, while the anterior membrane remains intact for about nine to eighteen months. ends Because of these birth sacs on the head, some diseases are easily detected in newborn babies.
For example, due to meningitis or brain injury, internal swelling starts. The reason for this is that the blood collected in the head puts pressure on the membranes due to which they swell. In the same way, when the child has diarrhea and the water in his body is sufficient. If it goes, these membranes shrink and the head also shrinks.
Blood would come out In this way, swelling and shrinking of the head can detect some diseases in newborn babies Are is close to Jer after the rush Blood membrane Ani Khushi
MUSCLES
How do the muscles of the body work? Muscles play an important role in moving our organs. Bones are not covered with thick layers of meat fibers which are called TISSUES. These tissues join together to form muscles. A characteristic of muscle fibers is their ability to contract and stretch, allowing them to move the bone they are attached to back and forth. are This Hardly final Did In fact, there is a layer of muscles on the bones in the body. These muscles are attached to both ends of the bone in such a way that when they contract, they pull the bone towards them and when they expand, the bone returns to its place. This is how that organ of our body moves. Is. Oh Of the jinns In addition, you play an important role in moving the bones. They are called skeletal muscles. Because the movement of these muscles is optional. That is, it is in the heart of the human being, so they are also called voluntary muscles are The movements of our hands, feet and neck etc. are due to muscles.
