Functions of Bones
Whenever the bones meet in the human body there is a joint formed which performs a special function in our body. Some big joints such as hip and shoulder joint perform many functions at the same time. Their power and capacity to move has to be experienced to be believed. Some other joints, such as those in the skull, are totally immovable.
Movable joints are supported by ligaments. Muscles also move and support the joints to some extent.
Without bones, the human body would not have the shape which is seen by others. It would have no power to sit, stand or move. Essential minerals such as calcium and phosphorus are stored and distributed by them. Blood cells are produced by the red marrow which is contained in the spongy centers of bones.
The bones in males are larger and heavier than the bones in the female. The female pelvic cavity is wider than the male pelvic cavity. If it were not so it would be difficult for a woman to give birth to a baby in the normal manner.
The human legs carry a lot of weight for a lifetime. The fingers of the hand can catch hold of an object and manipulate it in a delicate fashion, and with these artists create immortal paintings and sculptures. The rib cage is a protective cushion for the heart, the lungs and major blood vessels of the body. The pelvic girdle protects and supports the internal organs of the lower abdomen. The spinal cord or the backbone is protected by the surrounding vertebral column.
