2
Q

What is the anatomy of the musculoskeletal system?

A

A
  • Further damage
  • Delay in transport
  • Reduction of distal circulation
  • Aggravation of the injury

No matter how bad a fracture is, ABC’s are a priority!

38

*book*

A
39
Q

WHat is: symphysis, joint capsule, synovial membrane, synovial fluid, balll and socket joint, hinge joint

A
  1. Symphysis: bone ends are held together by fibrous tissue
  2. Joint capsule: a fibrous sac that holds together bone ends of a joint
  3. Synovial membrane: inner lining of the joint capsule. Creates synovial fluid
