Sample Answer

The muscular and skeletal systems work together as lever systems. Muscles attach to bones at origin and insertion points, creating movement through contraction and relaxation.
First aid intervention is required when movement causes sudden sharp pain or muscle inability to contract. Visible deformity or loss of joint stability indicates possible strain, sprain or fracture.
Warning signs include hearing a “pop” sound at time of injury, immediate swelling, or inability to bear weight on the affected area.
