The Five Main Functions

• Support ~ the skeleton gives you shape and support to your body.• Protection ~ bones protect your internal organs. For example the ribs

protect the heart and lungs while the skull encloses the brain.

• Movement ~ major muscles are attached to the bone to help them move

• Blood Cell Formation ~ blood cells are formed in the center of many bones in soft tissue called red marrow

• Storage ~ major quantities of calcium and phosphorous compounds are stored in the skeleton for later use. Calcium and phosphorous make bones hard


THE MAJOR ORGANS

• the bones are the major organ.

•


The skull

• The skull is one of the most important structures of the body considering the fact that it protects your brain a very important organ. The skull provides framework for most of your sensory organs such as the eyes, ears, tongue, and some skin.


The Rib Cage

• The rib cage provides protection for the lungs, heart, stomach liver and other parts of the upper abdomen. The rib cage has 24 ribs over all.


THE SPINE

The spine is a very flexible but fragile structure . If you break your back in a certain area you may become paralyzed. This structure has 26 bones in it.


AXIAL AND THE APPENDICULAR SKELETON

The axial skeleton includes the skull, the hyoid bone, the vertebral column (spine, sacrum, and coccyx), the sternum, and the ribs. Its components are aligned along the long axis of the body.

The appendicular skeleton includes the bones of the upper extremities (arms, forearms, and hands), the pectoral (shoulder) girdle, the pelvic (hip) girdle, and the bones of the lower extremities (thigh, knee, leg, and foot). Its components are outside the body main axis.

Other Systems that Work With it.

The Circulatory System because the blood is made up of bone marrow

The Muscular System because the bones are held up by the muscles to get posture and movement.

The Immune System because the immune system attacks the synovial membranes that lubricate joints causing inflammation at the joints


THE ROLE OF HOMEOSTASIS

Bones play an important role in regulating blood calcium levels, which must be maintained within narrow limits for functions such as muscle contraction and membrane potentials to occur normally.


A Few Of The Diseases You can get in Bones

LeukemiaBursitisOsteoporosisArthritisScoliosis Tendinitis


Types Of BonesThe long bones ~ in the limbs, they are thin, hollow and light, they play as essential role in all types of movements.

Flat Circular bones ~ bones that form the spine or vertebral column

Long Circular Bones ~ Ribs, they are strong but elastic giving the chest the flexibility and springiness it needs for breathing.

Flat irregular bones ~ shoulder, blades, hips and skull these are strong but light and protect delicate organs, such as the brain.


The End (:

• Without the skeletal system we would not move at all
