Articular System
| Question | Answer |
|---|---|
| Abduction | Away from midline |
| Adduction | Towards midline |
| Amphiarthosis | Slightly moveable cartilaginous joint (IVD, Pubic) |
| Ball + Socket Joint | Joints with one bone containing ball-shaped head |
| Bursae | Sacs of synovial fluid, reduces friction |
| Cartilaginous Joints | Amphiarthrotic joint |
| Condyloid Joint | Allows movement of 2 planes (wrist) |
| Diarthrosis | Freely moveable synovial joint |
| Dorsiflex | Toes to nose, extension at ankle joint |
| Ellipsoidal Joint | - Condyloid Joint - Synovial - Movement in 2 planes |
| Eversion | Sole of foot turns outward away from midline |
| Fibrous Joints | - Synarthrotic joint - Classified by length of fibers - No joint cavity |
| Flexion | Decrease angle of a joint |
| Gliding Joint | - Plane/Planar Joint - Synovial - Nonaxial - Flat articular surfaces |
| Gouty Arthrisis | Inflammation of joint from gout (Increased uric acid) |
| Hinge | - Synovial Joint - Single plane motion - Flex/extension only |
| Inversion | Sole of foot turns inward towards midline |
| Lateral Rotation | Rotation away from midline, External Rotation |
| Medial Rotation | Rotation towards midline, Internal Rotation |
| Osteoarthritis | - Most common arthritis - Degenerative joint disease - Non-inflammatory |
| Pivot Joint | - Uniaxial - Rotation in 1 plane (Shake head no) |
| Plane Joint | Gliding joint |
| Plantar Flex | Toes point down, Ankles in flexion |
| Protraction | Movement of body part anteriorly |
| Retraction | Movement of body part posteriorly |
| Rheumatoid Arthritis | Inflammatory autoimmune causing joint deformation |
| Saddle Joint | Thumbs only, Resembles condyloid joint |
| Symphysis | - Type of cartilaginous joint - Amphiarthrotic / No joint cavity - End of bone covered in hyaline cartilage and fibrocartilage |
| Synarthrosis | - Relatively immovable fibrous Joint - No cavity (Suture) |
| Synovial Fluid | - Within synovial joint capsule - Bursae - Tendon sheath + articular cartilage |
| Synovial Joints | Diarthrotic with a capsule + articular cartilage |
| Tendon | Connects muscle to bone, made of collagen |
| Tendon Sheaths | Wraps around tendons in synovial fluid; prevents friction |
| Types of Arthritis | Rheumatoid, Osteo, Gout, Spondyl, Septic(Blood poison), Lyme Disease |
| Types of Bursitis | Olecranon, Ischial, Prepatellar, Subdeltoid, Bunions |
| Circumduction | Cone-shaped movement of limb, proximal end, fixed position |
