Two examples of cartilaginous joints
Synchondroses - epiphyseal plate
Hyaline cart
Symphyses - pubic
Hyaline cart and fibrocart
Types of fibrous joints (3) and example of each
Sutures -saggital
Syndemoses - distal tibliofibular joint
Gomphoses - peg and socket tooth
Characteristics of fibrous
Bones joined by Ct fibers
No cavity
Little/no movement
Characteristics of fibrocart joints
United by cart
No joint cavity
Limited/ no movement
Features of synovial joint
Art cart Joint cavity Articular capsule encloses articulation - dense irreg ct / membrane Synovial fluid lubes and nourished cart Ligaments Nerve and bv Bursae &tendonn sheaths - reduce friction Fatty pads - cushion Mesenci - fibrocart wedge and stabilizes
