Flashcards
Joints, Synovial Fluid and Cartilage
Cards in this deck (19)
- 1What are the three types of joints?Fibrous
Cartilaginous
Synovial - 2Give 3 examples of fibrous jointsSuture (in skull)
Syndesmosis (joints held together by a ligament)
Gomphosis (holds tooth in socket) - 3What are some differences between a primary cartilaginous (synchondrosis) and a secondary cartilaginous (symphsis) joint?Primary cartilaginous - hyaline cartilage, allows for growth (e.g. epiphyseal plate of cartilage)
Secondary cartilaginous - hyaline and fibrocartilage, found in the midline (e.g. intervertebral joints, pubic symphysis, sternomanubrial joint) - 4What are the two types of cartilage found in synovial joints?Hyaline cartilage
Fibrocartilage - 5T/f - fibrocartilage is weight-bearing cartilage and therefore stronger than hyaline cartilage?True
- 6What produces the synovial fluid in a synovial joint?The synovial membrane
- 7List some types of synovial joints and give examplesPivot - atlanto-axial joint
Plane - acromioclavicular joint
Hinge - elbow joint
Saddle - carpometacarpal joint
Condyloid - metacarpophalangeal
Ball and socket - hip joint - 8What movement does a pivot joint allow for?Rotation
- 9What movement does a plane joint allow for?Gliding or sliding movements
- 10What movements does a hinge joint allow for?Flexion and extension
- 11T/f - saddle joints only allow for movements in one planeFalse - 2 planes
- 12What movements do a condyloid joint allow for?Flexion and extension
Abduction and adduction
Circumduction
- 13T/f - a ball and socket joint will not allow for much movementFalse - a ball and socket joint allows for movement on several axes
- 14What are some other features of a synovial joint?Articular discs
Ligaments
Bursae - 15What is the function of articular discs in synovial joints?To separate synovial cavities to allow for movement
- 16What is a bursa in a synovial joint?A sac filled with fluid to reduce friction
- 17What is the function of the synovium?To produce synovial fluid from the synoviocytes and transports nutrients to the cartilage and removes waste from the cartilage
- 18What are some of the main functions of synovial fluid?Lubrication (boundary, hydrodynamic and weeping)
Nutrition of cartilage
Removal of waste products - 19How does ageing affect joints?The viscosity of synovial fluid increases, meaning slower joint movements and reduced lubrication
The water content of cartilage decreases, meaning reduced shock absorption
