**FIBROUS JOINTS**
Fibrous joints connect bones together without movements. Examples: skulls, pelvis, union of the spinous process, andvertebrae are held by fibrous joints.

h there are three types of fibrous joints 1. Syndesmosis ex: radius and the ulna, tibia and fibula 2. Suture 3. Gomphosis
 * connects two bones by interosseous ligaments
 * slightly movable articulation
 * type of fibrous joint that only occurs in the skull or the cranium.
 * bones are immovable
 * immovable articulation
 * binds the teeth to the bony sockets in the maxillary and mandible regions.

**CARTILAGINOUS JOINTS**
Hyaline cartilage or fibrocartilage connect bones

There are two types of Cartilage: 1. Synchondrosis ex: sternal coastal joint (where the rib meets the sternum) allowing the lung to expand. 2.Symphysis ex: pubic symphysis
 * joint that connects with the cartilage
 * very strong and stiff
 * appars in childhood but disappears during adulthood
 * slightly movable
 * permanent

**SYNOVIAL JOINTS**
It is the most complex joints in our body and allows free movements. There are three types of synovial joints: 1. Uni-axial -- permits movement in one axis only - allows movement lie one plane - functions like a door opening and closing ex: elbow - allows rotary movements along the vertebrae regions - rotation, twisting, and turning ex: turing the head side by side, movement of the forearm against the upper arm 2. Bi-axial -- two chief axes of movemnt - allows movement in the sagittal and frontal plane - flexion, extension, abduction, adduction, and circumduction allowed ex: thumb //- allows all movement except for axial// 3. Multi-axial -- joint that occurs in the numbers of axes. - allows one part to rotate at almost angle ex: hip and the shoulder - allows only gliding movements ex: wrists and ankles
 * Hinge joint
 * Pivot or trochoid joint
 * Saddle or sellar joint
 * Condylar or ellipsoidal joint
 * Ball and socket joint
 * Gliding or plane joint
