KINDS OF JOINTS:

FABROUS JOINTS (FIXED) – are the connections between bones that held together by fibrous connective tissue that includes many collagen fibers. (No Synovial Cavity/ Fluid)

CARTILAGINOUS JOINTS (SLIGHTLY MOVEABLE) – are connections between bones that held tightly together by cartilage – specifically either hyaline cartilage or fabrocartilage. (No Synovial Cavity/ Fluid)

SYNOVIAL JOINTS (FREELY MOVEABLE) - have a synovial cavity between the articulating bones. This cavity is filled with synovial fluid that reduces the friction at the joints, enabling are articulating bones to move freely.

CLASSIFICATION OF SYNOVIAL JOINTS:

NAME DESCRIPTIONS EXAMPLES

Gliding joints(or plane joints)

These joints allow only gliding or sliding movements, are multi-axial such as the articulation between vertebrae.

carpals of the wrist, acromioclavicular joint

Hinge joints These joints act as a door hinge does, allowing flexion and extension in just one plane

elbow (between the humerus and the ulna)

Pivot joints One bone rotates about anotheratlanto-axial joint, proximal radioulnar joint, and distal radioulnar joint

Condyloid joints(or ellipsoidal joints)

A condyloid joint is where two bones fit together with an odd[citation needed] shape (e.g. an ellipse), and one bone is concave, the other convex; some classifications make a distinction between condyloid and ellipsoid joints,these joints allow flexion, extension, abduction, and adduction movements(circumduction).

wrist joint (radiocarpal joint) temporomandibular joint

Saddle jointsSaddle joints, which resemble a saddle, permit the same movements as the condyloid joints but allow greater movement

Carpometacarpal or trapeziometacarpal joint of thumb (between the metacarpal andcarpal - trapezium), sternoclavicular joint

Ball and socket joints"universal Joint" These allow for all movements except gliding

shoulder (glenohumeral) and hip joints
