Contemporary Classification (C. Diarthrosis....Classification) Flashcards
What is a simple synovial joint (diarthrosis)?
Only one pair of articulating surfaces are observed
What is a compound synovial joint (diarthrosis)?
More than two articulating surfaces are present in the same synovial joint
What is a complex synovial joint (diarthrosis)?
Within the simple joint or the compound joint, the articulating surfaces are separated by an articular disc (intra-articular disc) or meniscus
What morphological classification of synovial joints is classified as nonaxial?
Plane (diartrhosis arthrodial)
What morphological classifications of synovial joints would be classified as uniaxial?
Hinge (diarthrosis ginglymus) and pivot (diarthrosis trochoid)
What morphological classifications of synovial joints would be classified as biaxial?
(Diarthrosis) bicondylar, (diarthrosis) condylar, (diarthrosis) ellipsoidal, and saddle (diarthrosis sellar)
What morphological classification of synovial joints would be classified as multiaxial?
Ball and socket (diarthrosis enarthrosis), (diarthrosis spheroidal), (diarthrosis cotyloid) are all classifications given to the same type of joint
What are examples of synovial plane (diarthrosis arthrodial) joints?
Most zygapophyses of the vertebral column intercarpal, carpometacarpal and intermetacarpal joints of the hand intercuneiform, tarsometatarsal and intermetatarsal joints of the foot
What are examples of synovial hinge (diarthrosis ginglymus) joints?
Humero-ulnar joint of the elbow and interphalangeal joints of the fingers and toes
What are the examples of synovial pivot (diarthrosis trochoid) joints
Median atlanto-axial joint and proximal radio-ulnar joint
What are examples of diarthrosis bicondylar joints?
Temporomandibular joint and femur-tibia joint of the knee
What are examples of diarthrosis ellipsoidal joints?
Radiocarpal joint of the wrist, metacarpo-phalangeal joints of the hand, metatarsal-phalangeal joints of the foot and the atlanto-occipital joint of the vertebral column
Which synovial joint classifications are now often interchanged in textbooks?
Ellipsoidal and condylar synovial joints
What are examples of synovial saddle (diarthrosis sellar) joints?
Carpometacarpal joint of the thumb, talocrural joint of the ankle and the calcaneocuboid joint of the foot
What are examples of diarthrosis enarthrosis joints?
Femur-acetabulum of the innominate articulation at the hip and the humerus-glenoid cavity of the scapula articulation at the shoulder
