Functional Classification
What functional class is Synarthrosis?
Immobile
Gomphosis
What is peridontal membranes that hold the tooth to the bony jaw?
Suture
Dense regular connective tissue connects skull bones
Characteristics of fibrous structures
Dense regular connective tissue holds together the ends of bones and bone parts; no joint cavity
Carpals, Tarsals, articulating facets of vertebrae
Uni-axial, Plane (Gliding) Joint
What functional classification is Ampiarthrosis?
Slightly mobile
Symphisis
What is fibrocartilage between bones?
Syndesmosis
Dense regular connective tissue fibers (interosseous membrane) between bones
Characteristics of cartilaginous structures
Pad of cartilage is wedged between the ends of bones; no joint cavity
Humerulnar joint, tibiafemoral joint, talocrural joint, interphalangeal
Uni-Axial, Hinge joint
What function classification is Diarthrosis?
Freely Mobile
Synchondrosis
What is Hyaline cartilage between bones?
Hinge Joint
Convex feature of one bone fits into concave depression of another bone
Characteristics of synovial structures
Ends of bones covered with articular cartilage; joint cavity seperates the articulating bones; joint enclosed by an articular capsule, lined by a synovial membrane; contains synovial fluid
Dens of axis atloaxial joint, radioulner joint
Uni-Axial, Pivot Joint
What functional classification is Atlantoxial Joint?
Diarthrosis (Freely Mobile)
Plane joint
What is flattened or slightly curved faces that slide across one another?
Saddle joint
saddle-shaped articular surface on one bone closely interfaces with a saddle-shaped surface on another bone
Give example of a fibrous joint
tooth to jaw, lambdoid suture, articulation between radius and ulna and between tibia and fibula
Head of humerus, head of femur
Multi-axial, Ball & Socket Joint
What functional classification is the articulation between the tibia and fibia?
Amphiarthrosis (Slightly Mobile)
Condylar Joint
Oval articular surface on one bone closely interfaces with a depressed oval surface on another bone
Ball-and-socket joint
Round head of one bone rests within cup-shaped depression in another bone
Give example of synovial joint
