If we take a quick glance on a human body, we see different parts like hands, legs, eyes, ears, nose and so on. These parts have distinct functions to do like hands to write or type, legs to walk or run, ears to hear, eyes to see, etc. What makes them capable of doing these activities is what they are framed of. Human anatomy is deeper than what we see from out. Let’s learn about human anatomy on skeletal system of a body.
SKELETAL SYSTEM & LOCOMOTION
Locomotion is the process of movement from one place to another. Locomotion of a body is the efforts of bones and muscles present in them. If we strip off the parts like skin, muscles, internal organs, we will get a system of bones called skeleton (skeletal system). This system of bones frames the shape and supports the body. There are 206 bones in an adult body, and helps in the locomotion and protect various vital organs present.
Joints are the points where two bones meet and aids in the movements. There are two types of joints: movable and fixed joints.
Skeletal System is the framework of a human body. Skeletal system includes bones from top to bottom. At the top we have the skull, moving down ribcage in the front and backbone (vertebral column) at the back, lastly bones of limbs (arms and legs). Throughout these bones, we can see different types of joints. In addition to locomotory action, bones take up the role of a shield. They protect many vital organs from mechanical and other physical damages. For example,
- Ribcage protects the lungs
- Skull protects the brain
- Backbone protects the spinal cord
Thus we have discussed about the skeletal system and its role in the functioning of the human body. While learning about this topic, students would be naturally curious to see the working of the same by doing some practice exercises like the one given here- NCERT solutions for body movements.
