Support (your frame) and protection for your organs
Two things the Sun provides is heat and light.
Fibula and tibia
The brain controls the skeletal & muscles & the heart provides the blood to support the muscles.
the skeletal system and the nervous system
Two main functions include protection and support. A third function that can be considered is that it provides a place for muscles to attach to.
it provides food and most important the oxygen
There are two system that do this. Your skeleton (bones) and your skin (integument).
The two main divisions of the skeletal system are the axial skeletal system and the appendicular skeletal system.
The muscular system allows you to move by contracting and relaxing muscles to generate motion. The skeletal system provides structure and support to the body, allowing muscles to pull on bones to create movement.
Internal organs and the skeletal system are two different things, so there really is no such thing as "the internal organs of the skeletal system." The skeletal system is responsible for the support of the body and protection of the internal organs, and doesn't have internal organs in itself.
A spider is lacking a skeletal system. -------------------------- also note: 'skeletal system' is two words not one!
The muscular system provides the force needed to bend the arm by contracting the biceps muscle, while the skeletal system, specifically the elbow joint, allows for the bending motion to occur by providing a point of movement.
