The hard structures in our body are the bones. Bones cannot be bent. There are many bones present in each part of the body. We can bend or move our body only at those points where bones meet. There are different types of joints in our body to help us carry out different movements and activities. Ball and socket joints : In these type of joints ,The rounded end of one bone fits into the cavity (hollow space) of the other bone. Such a joint allows movements in all directions. Shoulder and arm joint Hip and thigh joint are examples of ball and socket joint. Pivotal Joint : The joint where our neck joins the head is a pivotal joint. It allows us to bend our head forward and backward and turn the head to our right or left. In a pivotal joint a cylindrical bone rotates in a ring. Hinge joints : The elbow has a hinge joint that allows only a back and forth movement. Hinge joint is at knee also. Fixed joints : The bones cannot move at some joints. Such joints are called fixed joints. There is a joint between the upper jaw and the rest of the head which is a fixed joint. BONE & MUSCULAR SYSTEM All the bones in our body also form a framework to give a shape to our body. The human skeleton is composed of around 305 bones at birth. The number of bones in the skeleton changes with age. It decreases to 206 bones by adulthood after some bones have fused together. This framework is called the Skeleton. We could know this shape better would be to look at Xray images of the human body. Our wrist is made up of several small bones called carpals. When we take a deep breath our chest bones and the back bone by gently pressing the middle of the chest and back at the same time. We can call bones of the chest as Ribs. Ribs join the chest bone and the backbone together to form a box. This is called the Rib cage. We can feel two bones on the back are prominent where the shoulders are. They are called Shoulder bones. Pelvic bones, enclose the portion of your body below the stomach. This is the part you sit on. The skull is made up of many bones joined together. It encloses and protects a very important part of the body, the brain. Muscles : The muscle bulged due to contraction (it became smaller in length). We can observe contraction of muscles in your leg when you walk or run and muscles of arm when it is stretched. Two muscles work together to move a bone. Muscles work in pairs. When one of them contracts, the bone is pulled in that direction. The other muscle of the pair relaxes. 1. Which is the second most abundant metal in the earth’s crust? – Iron 2.
