Joint Classifacation Flashcards
Synarthrosis
Junction between bones allowing little to no movement (sutures of the skull)
- Primary function: firmly bind bones together and transmit forces from one bone to another
Amphiathorosis
Formed primarily by fibrocartilage and hyaline cartilage (inter-vertebral disc) - Allow limited amounts of motion
- Primary function: provide shock absorption
Diarthrosis (synovial joint):
- Articulation that contains a fluid-filled joint cavity between two or more bones
Synovial fluid/membrane
provides joint lubrication and nutrition
Articular cartilage
- dissipates and absorbs compressive forces
Articular capsule
connective tissue that surrounds and binds the joint together
Capsular ligaments
- thickened regions of connective tissue that limit excessive joint motion
- Blood vessels
provide nutrients to the joint
- Sensory nerves
transmits signals regarding pain and proprioception (sensory awareness of the body’s position)
2 ball and socket joints
