Short Notes

Your bones cannot move by the Muscle. They need something to move. The bones in the body are covered with muscles. Muscles are just below your skin. The muscles and bones together help in moving the part of your body. They also give shape to the body. It is the muscles and bones of the hands that make your hands able to dance and write. Muscles are made up of tough elastic tissues. These are attached to the bones by a tough band of tissues called tendons. The muscles tighten and relax themselves to produce movement. There are about 640 muscles in your body. Muscles can only pull the bones. They cannot push them.So, to move the bones, at least two muscles are required. For example, when you bend your arm,one muscles, i.e. biceps contracts and gets shortens,that is the muscles on top become stiff. while the lower muscles, the triceps, stretch. when you stretch back your arm, the upper muscles stretch and the lower muscles contract. There are three kind of muscles The muscles which ...

Arms and legs are the main base of our body. we cannot work without it. The framework of each upper and lower limbs is made up of three long and small bones. The upper limbs, called the forelimbs or arms, are joined to the backbone with the help of shoulder girdle (shoulder blade and collarbone make up the shoulder girdle). The arm has one long bone called the humerus. The lower arm has two long bones. The wrist and hands have several small bones. The bones of the lower limbs, called the hind limbs or legs are attached to the hip bone(hip bone is made up of three bones joined together). The upper half or the thigh bone of the leg, also called the femur, is the longest bone in the body and bears the weight of the whole body. The lower half of the leg has the shin bone and the calf bone. There are several small bones which make up the foot. NOTE: The long bones of the arms and legs are hollow tube-like structures. such structures are very strong which can hold weight and tolerate...

Read about brain function for educational purpose .Here given some information of structure of Skull in English.शरीर का मुख्य भाग खोपड़ी की संरचना की जानकारी नीचे दी जा रही हैं। The brain is the most remarkable organ in your body. It is the control center of your body. Message from different parts of the body tell the brain what is required by the body. The brain then tells every part of the body, by sending messages, what to do and how to do, even when you are asleep.

The brain is soft and delicate organ like jelly. It looks like a walnut. It is protected within a bony framework called the skull. The space between the brain and skull is filled with a fluid. The brain has three parts-the cerebrum, the cerebellum and the medulla. CEREBRUM: It is the largest part of the brain which helps us to...

Human skeletal is the base of our body. It is structure of bones. Without it we cannot image the human body. The human skeletal is made up of 206 bones which are arranged in definite manner. Bones are made up of cell. They are hard aur tough on the outside, but are soft and spongy from the underside. The underside of a bone has soft jelly-like material called the bone marrow, which makes blood cells in the body. Bones are hard and are of different shapes and size. For example, the arm and leg bones are long, while the bones in your little fingers are short. All of us have a skeletal made up of same kind of bones which are arranged in the same manner. The skeletal has three major function. *It supports your body and gives shape to your body. Without skeletal, your body would be like jelly. *It protects the internal organs of the body .For example, the skull protects your brain, while the ribcage protects your heart, liver and lungs. *It helps you to move.
