Introduction

´╗┐Glenn Nelson Structure and Functions of Skeletal system Movement Bones provide the structure for muscles to attach so that our bodies are able to move. Protection ? The skeleton protects vital organs of the body such as the lungs and it is where the blood cells are manufactured to fight diseases. Support ?

Conclusion

There are five metatarsals. Phalanges Long Phalanges are better known as your fingers and toes. You have 14 phalange bones in each hand and 14 in each foot Pelvis Flat Your pelvis is your hip bones. Femur Long Largest bone in the body. More commonly known as the thigh bone. The Patella Sesamoid Your kneecap is the patella. The patella is a round shaped bone. Fibula Long This long thin pin-like bone is found on the outside of the tibia. The fibula's main job is to provide sites for muscles to attach and also adds support to the Tibia Tibia Long This bone is also known as the shinbone. The tibia is the second largest bone in the skeleton and is found in the lower leg. Tarsels Short These are the bones in your ankle. There are seven tarsal bones that allow for movement in the foot. ...read more.
