Musculoskeletal System

The musculoskeletal system has many jobs. It ​ (a)   the muscles and organs within the body. The skeleton also provides ​ (b)   for the main organs in the body. Both skeletal and muscle systems are also used for ​ (c)   - This means moving.

• Supports
• Protection
• Locomotion
• Separates
• Controls
• Unification

The skeleton is split into two sections - the ​ (a)   skeleton is in the centre of the body and allows support and protection. It contains bones such as the ​ (b)   , as well as the ​ (c)   cage.

The ​ (d)   skeleton is the bones of the limbs - This allows us to ​ (e)   .

• Axial
• Spine
• Rib
• Appendicular
• Move
• Ulna
• Tibia

Match the following words about the spine with their job

• A series of small bones forming a flexible and supportive structure down the back - Lets us bend

• Spinal Cord

• These cushion the force on the vertebrae acting as shock absorbers - low friction as vertebrae shift

• Cartilage Discs

• A massive bundle of nerve fibers that contain neurones and transmit action potential

• Vertebrae

Where bones meet we call a _____

Match the following type of joint with its description

• Connection between moving bones made up of cartilage - acts as a shock absorber and reduces friction

• Synovial Joints

• Fixed immovable joints - Connective tissues hold joints tightly together

• Fibrous Joints

• Synovial fluid is found between the moving bones which reduces friction

• Cartilaginous Joints
