Functions of the Skeletal System
The skeletal system offers a multitude of functions that extend beyond providing structure and framework.
Bones serve as a protective casing for delicate internal organs, such as the skull protecting the brain, the rib cage safeguarding heart and lungs, and the vertebral column shielding the spinal cord.
Shape and Support
Bones act as the framework upon which all other body tissues and organs are anchored. They give the body its shape and help maintain an upright posture.
This combination of bones and muscles allows us to perform a wide range of activities.
Mineral Storage and Release
Bones are a reservoir for important minerals, primarily calcium and phosphate, which are released into the bloodstream when needed.
The bone marrow stores fat cells which serve as a massive energy reserve and can be drawn upon when the body is in need of it.
Production of Blood Cells
Red bone marrow produces the red blood cells, white blood cells, and platelets that are necessary for clotting blood, carrying oxygen, and fighting infections.
The middle ear bones (anvil, hammer, stirrup) help transmit the sound from the eardrum to the inner ear, allowing us to hear things.
