| Question | Answer |
| Types of Joints Articulations | Synovial Joint Fibrous Joint Cartilagenous Joint |
| Synovial Joints | most common type promotes movement at articulating ends of bones covered with cartilage and has fibrous capsule casing |
| Plane (Synovial) Joint | AC joint usually uniaxial permits gliding or sliding |
| Hinge (Synovial) Joint | Elbow joint Uniaxial permits flexion and extension only |
| Ball and Socket (Synovial) Joint | Hip/Shoulder Joint multiaxial permits several axes movements |
| Pivot (Synovial) Joint | Atlanto-axial Joint Uniaxial provides rotation |
| Condyloid (Synovial) Joint | MCP Joints biaxial permits flexion, extension, abduction, adduction, and circumduction |
| Saddle (Synovial) Joint | Thumb joint - 1st metacarpal joint biaxial permits movement in 2 different planes |
| Articulations of Synovial Joints | made of hyaline articular cartilage with articular capsule (fibrous layer and synovial membrane) filled with synovial fluid |
| Types of Fibrous Joints | Suture - Ex. cranium Syndesmosis - Ex. between the tib/fib Gomphosis - Ex. alveolar process of jaw |
| Suture Joint | bones close together,either interlocking along a wavy line or overlapping |
| Syndesmosis Joint | unites bones with sheep of fibrous tissue, either a ligament or fibrous membrane partially movable (pronation/supination) |
| Gomphosis or socket Joint | dento-alveolar syndesmosis has peg-like process fitting into a socket articulation between the root of the tooth and alveolar process (associated with proprioception) |
| Types of Cartilagenous Joint | Synchondrosis (primary) Symphysis (secondary) |
| Synchondrosis (primary cartilaginous) Joint | temporary reunions of bones united by hyaline cartilage, permitting slight bending during early life - permit growth of bone |
| Symphysis (secondary cartilaginous) Joint | strong, slightly movable joints united by fibrocartilage - provide strength and shock absorption and flexibility Ex. Intervertebral discs |
