__**Fibrous joints**__

====Fibrous joints are found between two bones connected by fibrous tissue (collagen). There are 3 different types of fibrous joint: sutures, gomphoses and syndesmosis. ====


 * = Fibrous Joints ||= Description ||= Example ||
 * = **Sutures** ||=  The line of junction of two bones, especially of the skull,in an immovable articulation ||= Bone plates of the skull ||
 * = **Gomphoses** ||=  An immovable articulation in which one bone or part is received in a cavity in another, as a tooth in its socket ||= Restricted to the teeth in their sockets ||
 * = **Syndesmosis** ||= A connection of bones by ligaments, fasciae, or membranes other than in a joint ||= Between the shaft of the radius and ulna ||

__**Cartilaginous**__
====Cartilaginous joints are two bones connected by **//fibrocartilage//** or **//hyaline cartilage //**. There are two types of cartilaginous joints: synchondroses and symphyses. ====
 * = Cartilaginous Joint ||= <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Description ||= <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Example ||
 * = <span style="font-family: 'Comic Sans MS',cursive;">**Synchondrosis** ||= <span style="color: #333333; font-family: 'Comic Sans MS',cursive; font-size: 13px;">An immovable skeletal articulation in which the union is cartilaginous ||= <span style="font-family: 'Comic Sans MS',cursive;">A cartilaginous growth plate between two ossifying ends of a bone ||
 * = <span style="font-family: 'Comic Sans MS',cursive;">**Symphysis** ||= <span style="font-family: 'Comic Sans MS',cursive;">A symphysis is where two bones are joined together in the median plane by a fibrocartilage disc ||= <span style="font-family: 'Comic Sans MS',cursive;">Pubic symphysis ||

__**Synovial joints**__
<span style="font-family: 'Comic Sans MS',cursive;">Synovial joints are movable joints and have a large range of motion. There articular surfaces are covered with hyaline cartilage. This articular cartilage is avascular, non nervous and elastic. Lubricated with synovial fluid, the cartilage forms slippery surfaces for free movements.

 * = <span style="font-family: 'Comic Sans MS',cursive;">Hinge ||= <span style="font-family: 'Comic Sans MS',cursive;">Hinge joints are **//uniaxial//**, like the hinge on a door. Their movement is restricted to one plane by the shape of the opposing articular surfaces as well as the strong collateral ligaments along the sides of the joint. ||= <span style="font-family: 'Comic Sans MS',cursive;"> Knee and elbow joint (humeroulnar part). ||
 * = <span style="font-family: 'Comic Sans MS',cursive;">Gliding (plane) ||= <span style="font-family: 'Comic Sans MS',cursive;">Plane joints are **//uniaxial//**, their articular surfaces are flat and glide over each other. ||= <span style="font-family: 'Comic Sans MS',cursive;">Between the articular processes of the vertebrae. ||
 * = <span style="font-family: 'Comic Sans MS',cursive;">Pivot ||= <span style="font-family: 'Comic Sans MS',cursive;">A pivot joint is **//uniaxial//** and consists of a bony pivot (projection) within an osteoligamentous ring. ||= <span style="font-family: 'Comic Sans MS',cursive;">The atlas (C1) pivots around the dens of the axis (C2). ||
 * = <span style="font-family: 'Comic Sans MS',cursive;">Saddle ||= <span style="font-family: 'Comic Sans MS',cursive;">Saddle joints are **//biaxial//**, with both bones possessing concavoconvex surfaces; each surface is concave in one direction and convex in the other direction. ||= <span style="font-family: 'Comic Sans MS',cursive;">Carpometacarpal joint of the thumb (between the trapezium and the first metacarpal). ||
 * = <span style="font-family: 'Comic Sans MS',cursive;">Condyloid (ellipsoid) ||= <span style="font-family: 'Comic Sans MS',cursive;">Condyloid joints are **//biaxial//**, with an convex condyle that fits into a concave surface. They do not allow rotation. ||= <span style="font-family: 'Comic Sans MS',cursive;">Metacarpophalangeal joints. ||
 * = <span style="font-family: 'Comic Sans MS',cursive;">Ball and Socket ||= <span style="font-family: 'Comic Sans MS',cursive;">Ball and sockets joints are **//multiaxial//** and the most flexible joints in the body. They consist of a hemispherical head that fits into a cup-like depression. ||= <span style="font-family: 'Comic Sans MS',cursive;"> Hip and Shoulder joint. ||
