joint structure Flashcards
what are the common features of a synovial joint
- ligament
- synovial fluid
- articular cartilage
- joint capsule
- bursa or bursae
what is the structure of a ligament
a tough band of slightly elastic connective tissue
what is the function of a ligament
attaches bone to bone + stabilises the joint during movement
what is the structure of synovial fluid
Lubricating liquid contained within the joint cavity
what is the function of synovial fluid
reduces friction + nourishes articular cartilage
what is the structure of articular cartilage
smooth tissue which covers the surface of articulating bones
what is the function of articular cartilage
absorbs shock and allows friction-free movement
what is the structure of a joint capsule
a fibrous sac with an inner synovial membrane
what is the function of a joint capsule
encloses and strengthens the joint secreting synovial fluid
what is the structure of bursa/bursae
a closed, fluid-filled sac found where tendons rub over bones
what is the function of bursa/bursae
reduces friction between tendons and bones
