Structure and function of the musculoskeletal system Flashcards
What is a joint
A connection between two or more bones that allows movement
What is a long bone
A bone that allows gross movement e.g femur
What is a short bone
A bone that enables fine controlled movements e.g carpals, tarpans

A bone that provides protection e.g ribs, scapula, cranium
Name the 6 functions of the bonds
Strength, protection, movement, support, mineral storage, blood cell production
What do tendons do
Connect muscle to bone
What is the most common type of joint
Synovial joint
Name the parts of a synovial joint
Synovial fluid, joint capsule, cartilage, ligament, synovial membrane
What does synovial fluid do
Reduces friction between cartilage
What does the joint capsule do
Seals the joint and provides stability
What does cartilage do
Acts as a shock absorber
What does a ligament do
Connects bone to bone
What is a hinge joint
