|---|---|
| Joints: Functions (2) | Hold bones together, Provide skeleton with mobility. |
| Joints: Functions Classification (3) | Synarthroses, Amphiarthroses, Diarthroses. |
| Synarthroses | Immovable. |
| Amphiarthroses | Slightly movable. |
| Diarthroses | Freely movable. |
| Joints: Structure Classification (3) | Fibrous, Cartilaginous, Synovial. |
| Fibrous | Sutures, Syndesmoses, Gomphosis, Synostosis. |
| Sutures | Skull. |
| Syndesmoses | End of tibia/fibula. |
| Gomphosis | Teeth. |
| Synostosis | Ossification of bone. |
| Cartilaginous | Symphysis, Synchondrosis. |
| Symphysis | Pubic symphysis, Spinal disks, Ribs. |
| Sybchondrosis | Immobile; 1st rib, Sternum. |
| Synovial | Bone ends covered with cartilage and enclosed within a capsule lined by membrane. Shoulder, hip wrist. |
| Synovial Joints (6) | Plane, Hinge, Pivot, Condyloid, Saddle, Ball and Socket. |
| Plane | Nonaxial; Carpals. |
| Hinge | Uniaxial: Elbow, Ankle, Phalanges of Fingers, Knee. |
| Pivot | Uniaxial; Radius and Ulna, Atlas and Axis. |
| Condyloid | Biaxial; Metacarpals and Phalanges (Knuckles). |
| Saddle | Biaxial; Thumbs. |
| Ball and Socket | Multiaxial; Femur and Pelvis (Hip). |
| Herniated Disc | Disc between vertebrae gets displaced and presses upon spinal chord. |
| Spinal Curvatures (3) | Scoliosis, Kyphois, Lordosis. |
| Scoliosis | Sideways curve. |
| Kyphosis | "Hunchback". |
| Lordosis | Lumbar curves in "bubble butt". |
| Dislocation | Bone forced out of normal location. |
| Bursitis | Inflammation of the bursae membrane. |
| Sprain | Ligaments and tendons stretched or torn. |
| Osteoporosis | Where bones thin out (lose calcium) and become very fragile and form painful bony spurs. |
| Arthritis | Pain, stiffness, swelling of joints. |
| Arthritis Types (3) | Osteoarthritis, Rheumatoid, Gout. |
| Osteoarthritis | Cartilage softens and wears down. |
| Rheumatoid | Autoimmune disorder where body's immune system attempts to destroy its own tissues. |
| Gout | Where uric acid accumulates and deposits sharp crystals in the soft tissues of joints. |
| Uric Acid | Waste product of metabolism. |
| Hyperuricemia | Gout. |
