  • Hinge joint
  • Pivot joint
  • Condyloid joint
  • Ellipsoid joint
  • Saddle joint
  • Ball and socket joint

Synovial Joints

Types of joints Description Possible movement Example
Fibrous Articulating bones fastened together by a thin layer of dense connective tissues containing many collagen fibers    
1.Syndesmosis

(Amphiarthrotic)

Bones bounded by interosseous ligament Joint flexible and may be twisted Tibiofibular articulation
2.Suture

(Synarthrotic)

Flat bones united by sutural ligament None Parietal bones articulate at saggital suture of skull
3.Gomphosis

(Synarthrotic)

Cone-shaped process fastened in bony socket by periodontal ligament None Root of tooth united with mandible
Cartilaginous Articulating bones connected by hyaline cartilage of fibrocartilage    
1.Synchondrosis

(Synarthrotic)

Bones united by bands of hyaline cartilage None Joint between the first rib and the mandible
2.Symphosis

(Amphiarthrotic)

Articular surfaces of bones are covered by hyaline cartilage and the bones are connected by a pad of fibrocartilage Limited movement, as when the back is bent or twisted Joints between bodies of vertebrae
Synovial

(Diarthrotic)

Articulating end of bones surrounded by a joint capsule; articular bone ends covered by hyaline cartilage and separated by synovial fluid    
1.Ball and socket Ball-shaped head of one bone articulate with cup-shaped socket of another Movements in all planes( Multiaxial), including rotation Shoulder, hip
2. Condylar Oval-shaped condyle of one bone articulate with elliptical cavityof another Variety of movements in two planes (biaxial) but no rotation Joints between metacarpals and phalanges
3.Plane Articulating surfaces are nearly flat or slightly curved Sliding or twisting Wrist , ankle
4. Hing Convex surface on one bone articulate with concave surface of another Flexion and extension (uniaxial) Elbow , joints of phalanges
5. Pivot Cylindrical surfaces of one bone articulates with ring of bone and ligament Rotation (uniaxial) Joints between proximal ends of radius and ulna
6. Saddle Articulating surfaces have both concave and convex  regions; surface of one bone fits the complementary surface of another Variety of movements, mainly in two planes (Biaxial) Joint between carpal and metacarpal of thumb
