Skeletal system is a prime system of the body of human beings, which is composed of bones, cartilages and joints. These components mutually form a hard and rigid kind of framework, named skeleton. The skeleton is a quite unique composition. It happens to be tough and hard, however , concurrently it lets movements at many different regions. It also demonstrates good amount of flexibility at selected regions such as the spine.
The initial and also the vital part of skeletal system of human body is bone. Bones can be of several different types such as irregular bones, short bones, long bones, flat bones and sesamoid bones. All of them have their individual value in formation of the skeletal frame. Bone on its own is a specific type of connective tissue, which is certainly impregnated with inorganic salts certainly the salts of calcium. This unique impregnation helps it be solid and rigid, subsequently it can refuse forces of compression. This way, bones create an effective framework for the human body to be created around.
The next part of the skeletal system is cartilage. Cartilages are of three distinct variations: Fibrous Cartilage, Hyaline cartilage and Elastic Cartilage. Each one of them has a unique value. Cartilages are critical for elasticity and mobility in the rigid bony skeletal frame. One of the most noticeable illustration of flexibility is the spine, in which pads of fibrous cartilage (Intervertebral cartilaginous discs) exist between vertebrae and thus the spine can easily bend in several ways. Cartilages also form a critical part of joints, where they insure the articulating surfaces to relieve scrubbing.
The last part of skeletal system is formed by joints. Joints are components in the skeletal system where a association is made between “two bones”, “a bone and cartilage”, or “a cartilage and cartilage”. The key role of joints in skeletal system is that they enable movements in the hard and rigid framework. At joints, the bones can easily move in various directions therefore construct varieties of movements. These movements are crucial for all sorts of body exercises. This reflects the value of joints in human skeletal frame.
Skeletal system performs many tasks in body of a human. Essentially the most obvious of those are: protection of delicate organs, providing strength, support and shape, production of blood cells, and creating leverage for body movements. All these capabilities are vital for survival and a healthy life-style. The value of the functions completed by the skeletal system may be certainly understood in disorders caused by abnormalities of the components of skeletal system.
