joints Flashcards
fibrous joints
no synovial cavity; bones held together by dense irregular CT, rich in collagen fibre; SYNARTHROSIS (permits little/no movement)
Suture
1/3 types of fibrous joints; unites bones of skull; AMPIARTHROSIS in children; SYNARTHROSIS in adults
Syndesmosis
1/3 types of fibrous joints; greater distance btw articulating surfaces and more dense irregular CT than suture; AMPIARTHROSIS
Interosseous Membrane
1/3 types of fibrous joints; sheet of dense irregular CT that binds neighbouring long bones; AMPIARTHROSIS
Cartilaginous Joints
NO synovial cavity; bones held together by cartilage; SYNARTHROSIS
Synchondrosis
1/2 types of cartilaginous joints; connected by hyaline cartilage; SYNARTHROSIS, ie. epiphyseal growth plate
Symphysis
1/2 types of cartilaginous joints; hyaline cartilage at ends of articulating bones and fibrocartilage connects bones; AMPIARTHROSIS
Synovial Joint
only type of joint to have a synovial cavity; all types are DIARTHROSIS; united by dense irregular CT and accessory ligaments; bones at joints covered by hyaline cartilage
Ligament
main mechanical factor that holds bones close together in synovial joint (bone-bone)
Synovial fluid
secreted by synovial membrane; forms film over surfaces within articular capsule to reduce friction and absorb shock
Meninsci
within synovial joint; modifies joint surface allowing bones of different shape to fit tightly
Bursae
between skin and bone, tendon and bone, muscle and bone and ligament and bone; fluid-filled to cushion movement of one body part over another
the knee
synovial joint; each bone within joint is coated with articular cartilage and lubricated with synovial fluid; each bone is separated by fibrocartilage
