 Three types of joints structirally classified | Fibrous, Synovial, and Cartiliginous |
| Fibrous | bones are joined by dense fibrous connective tissue, has no cavity, mostly immovable |
| Three types of fibrous joints | sutures, syndesmoses, and gomphoses |
| Sutures | seams between bones of the skull |
| Syndesmoses | bones connected by ligaments, cords, or bands of fibrous tissue |
| Gomphosis | peg-in-socket firbous joint, ex. between teeth and bones |
| Types of cartilaginous joints | Synchrondoses and Sympheses |
| Synchondroses | immovable joints that are joined together, epiphyseal plates |
| Sympheses | the functional classification of joints held together by cartilage ex. vertebral discs slightly movable |
| Amphiarthrosis | slightly movable joints |
| Diarthrosis | freely movable joints |
| Synarthroses | immovable joints |
| Examples of Synarthroses | suture, gomphosis, syndchondrosis |
| Examples of Amphiarthrosis | Syndemosis, Symphysis |
| Characteristics of Diarthrosis | has synovial fluid secreted by the synovial membrane |
| Functions of synovial membrane | lubrication, provides nutrients to cartilage and ligaments |
| Ligament | holds bone to bone |
| Types of Diarthrotic joints | Ball and Socket, Hinge, Gliding, Pivot, Condyloid, Saddle |
| Ball and socket | joint in shoulder and hips, diarthrotic |
| Hinge | joint in knee and elbow, diarthrotic |
| Gliding | tarsals and carpals, diarthrotic |
| pivot | radial and ulna, one joint turns on axis, diarthrotic |
| Condyloid | wrist, double hinge, diarthrotic |
| Saddle | thumb, diarthrotic |
| Flexion | decreasing the angle between two bones |
| Extension | increasing the angle between two bones |
| Hyperextension | increasing the angle between two bones beyond normal range |
| Abduction | to move away from the midline |
| Adduction | to move towards the midline |
| Circumduction | to move in a circle |
| Elevation | to move up or superior |
| Depression | to move down or inferior |
| Protraction | to move out |
| Retraction | to move in |
| Inversion | moving the sole of thew foot inwards |
| Eversion | moving the sole of the foot outwards |
| Dorsiflexion | bringing the front of the foot up |
| Plantar Flexion | putting the front of the foot down |
| Supination | facing the palms up |
| Pronation | facing the palms down |
| Dislocation | pulling out of place, it tears the cartilage and tendons |
