The joints in the body are the places where two bones are joined together. The joints are strong enough to withstand jerks. The ends of bones are covered with soft cartilage. It acts as a shock absorber and reduces friction between the bones. Cartilage is also present in some parts of the body that are not as hard as the bones, for example the upper part of the ear. The bones are held together at the joints by strong, stretchy bands called Ligaments. There are many joints in the body. The joints are of three types, depending on the types of movement they allow—immovable, slightly movable and freely movable.
The bones in the skull (except the lower jaw bone) do not allow any movement. The joints between the ribs and the breast bone allow only slight movement. Most of the joints in the human body are freely movable joints. These freely movable joints are of four main types, depending on the type of movement they allow.
The joints do not allow any movement between the bones. For eg : the bone of skull are interlocked with each other and held together by fibrous cartilage, which do not allow any movement.
These joints allow very little movement due to the presence of a pad of flexible cartilage between their ends. For example, joints present between adjacent vertebrae in the backbone or spine allow only slight movement. This kind of joint provides more support.
The elbow, knee and finger joints allow movement in one plane only, that is, up and down, or backward and forward, like the hinges of a door. Such joints are therefore called hinge joints. We have hinge joints in our elbows, fingers, knees and toes.
The shoulder and hip joints allow movement in all directions. In such joints, the end of one of the bones is round like a ball. It fits into a hollow part (or socket) in the other bone.
The neck joint also allows movement in all directions. It allows you to move your head up and down, left and right and also to rotate it. In such joints, one of the bones ends in a rounded or conical surface that fits into a dent in the other bone. Such a joint is called a pivot joint.
The wrist or ankle joints have flattened ends of bones that can move ( or glide) against each other, These joints allow side to side as well as backward and forward movement. The vertebrae also have similar joints that allow slight movement. Gliding joints are found between the wrist and the carpals and between the ankle and the tarsals.

My experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
One of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
