What Are the Major Organs of the Skeletal System?

The skeleton is a framework of 206 bones that protect the body’s organs and provide support and attachment for muscles; this enables movement throughout the body. Bones making up the human skeleton are located inside the body; the skeleton is called an endoskeleton.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Skeletal Structure

The skeletal structure is divided into two groups named the axial skeleton and the appendicular skeleton. The axial skeleton consists of 80 bones which include the head and trunk of the human body. The appendicular skeleton is composed of over 126 bones in the lower region of the body.


Bones are a major organ of the skeletal system; their purpose is to protect and support the function of other organs in the body. Bones store minerals and provide blood protection while producing red and white blood cells.


Cartilage is a connective tissue that is composed of important cells and fibers; it's located throughout the body. Cartilage is an important organ in the skeletal system. It supports the structure of many body parts and functions like the bones, ribs, ears and nose.


A tendon is a skeletal organ that provides adhesive strength as it connects muscle to bone. Tendons withstand pressure and tension; they work collectively with muscles to enable rigorous movement.


Ligaments are organs that connect bone-to-bone in the skeletal system. They are fibrous tissues that provide stability to joints throughout the body during rest and active movement.
