Skeletal system of human body
May 3rd, 2011 Ahsan IqbalSkeletal system is a prime system of the body, which is comprised of cartilages, bones and joints. These basic tissues jointly form a hard and firm framework, referred to as skeleton of human body. The human skeleton is a pretty distinct composition. It happens to be tough and hard, however , concurrently it lets movements at numerous places. Moreover it exhibits amazing level of flexibility at a number of places much like the back bone.
The main as well as the most vital part of skeletal system of body is bone. Bones can be of several different types like irregular bones, short bones, long bones, flat bones and sesamoid bones. All of them have their individual necessity in formation of the skeletal system. Bone by itself is a specific variety of connective tissue, that is impregnated with inorganic salts certainly the salts of calcium. This kind of impregnation helps it be tough and stiff, therefore it can withstand forces of compression. In this manner, bones compose a useful system for the human body to be crafted around.
The next part of the skeletal system is cartilage. Cartilages are of three forms: Fibrous Cartilage, Hyaline cartilage and Elastic Cartilage. Each one of them has unique worth. Cartilages are critical for elasticity and mobility in the rigid bony skeletal framework. Probably the most obvious illustration of flexibility is the back bone, in which pads of fibrous cartilage (Intervertebral cartilaginous discs) can be found between vertebrae and so the spine is able to manipulate in several pathways. Cartilages also form an essential element of joints, where they insure the articulating surfaces to lower rubbing.
The 3rd part of skeletal system is formed by joints. Joints are parts in the skeletal frame where a joining is produced between “two bones”, “a bone and cartilage”, or “a cartilage and cartilage”. The main task of joints in skeletal frame is that they permit movements in the hard and stiff framework. At joints, the bones can easily move in distinct directions and so produce varieties of movements. These movements are important for all forms of body actions. This reflects the significance of joints in human skeletal system.
Skeletal system achieves many tasks in body. Quite possibly the most noticeable of these are: creating leverage for movements of the body, providing strength and support, protection of delicate organs, and production of blood cells. All of these attributes are critical for survival and a healthy life-style. The significance of the functions completed by the skeletal system may be properly appreciated in disorders as a result of abnormalities of the components of skeletal system.
