The development of the skeleton system and its role in physical activity
Learning Objectives Identify and describe the main functions of the skeleton – using practical examples
Main 5 functions 1. to give shape and support – enabling good posture 2. to allow movement of the body by providing sites for muscle attachment, and a system of levers 3. to protect the internal organs, heart, lungs, spinal chord and brain 4. to produce red and white blood cells 5. To store minerals
Red blood cells Why is the production of these so important? Oxygen to working muscles Why? Energy etc...
Axial skeleton The axial skeleton is the main source of support to the body. It is the central part of the skeleton Cranium Vertebral column Rib cage (12 pairs of ribs and the sternum)
Appendicular skeleton Consists of the remaining bones and includes the girdles that join these bones to the axial skeleton
