Document Summary

Synarthroses - bones are directly connected to each other via connective tissue. Direct connection - stability, not mobility = not much movement (we also don"t want it) Ex: connect distal end of tibia to fibula iii. Primary cartilaginous joints made up of hyaline cartilage ex: epiphyseal plates ii. Ex: pubic symphysis: two pubic bones meet interiorly and directly connected via cartilage. Joint capsule of fibrous tissue - cover joints. Fibrocartilaginous disks, plates, or menisci (in the knee) - function as shock absorber. Labrums - only two joints, both are ball and socket. Blood and nerve supply - every joints but hyaline cartilage have supply. Hinge - only flexion and extension (bone angle decreases and increases) Ex: atlantoaxial joint between atlas c1 and axis c2. One surface is often concave and another surface convex. Get flexion and extension (f/e) & adduction and abduction (ad/ab) Only two of this joint - hip and shoulder.
