| Question | Answer |
|---|---|
| Another Name for Joints | Articulation/Arthrosis |
| Joints are the | Point of contact for 2 or more bones, between cartilage and bones, between teeth and bones |
| Arthrology | The scientific study of joints |
| Joints permit | Normal and Abnormal movement |
| Kinesiology | Study of motion |
| Bursae | Fluid-filled sacs between tendons and bones |
| Bursitis | Inflammation of a bursa |
| Connective tissues in the joints are | Restrictive and Elastic |
| Joints have | Ligaments |
| Structural Classes of Joints | Fibrous, Cartilaginous, and Synovial |
| Based upon movement, synarthrosis means | Immovable |
| Based upon movement, amphiarthrosis means | Slightly Moveable |
| Based upon movement, diarthrosis means | Freely Moveable |
| The 3 types of Fibrous joints | Suture, Syndesmosis, Gomphosis |
| All fibrous joints are | Synarthrotic |
| An example of a suture fibrous joint | The skull |
| An example of a syndesmosis fibrous joint | Tibia and Fibula |
| An example of a gomphosis fibrous joint | Tooth in its socket |
| 2 types of Cartilaginous Joints | Amphiarthrosis and Synchondrosis |
| An example of an amphiarthorsis joint (slight movement) | Intervertebral discs |
| An example of a synchondrosis joint (no movement) | Epiphyseal growth plate |
| All synovial joints are | Diarthrotic |
| Ligaments hold | Bones in place |
| Synovial Joints have | Articular Cartilage, Joint Cavity, Synovial Fluid, Synovial Membrane, Fibrous Capsule, Ligaments |
| Meniscus | Fibrocartilage pad inside a joint cavity |
| Meniscus is located in | The knee and the temporomandibular joint (TMJ) |
| Types of Synovial Joints | Gliding Plane, Hinge, Pivot, Condyloid, Saddle, Ball and Socket |
| Disorders of the Skeleton | Osteoarthritis, Rhematoid Arthritis, Gouty Arthritis, Lyme Disease, Ankylosing Spondylitis |
| Osteoarthritis | Wear and tear of cartilage over time |
| Rhematoid Arthritis | Autoimmune; Pannus |
| Gouty Arthritis | Uric Acid build up |
| Lyme Disease | Spread by deer ticks, bullseye |
| Ankylosing Spondylitis | Fusion of vertebrae |
| Types of Movement | Flexion, extension, lateral flexion, abduction, adduction, rotation, pronation, supination, eversion, inversion, circumduction, dorsiflexion, plantarflexion |
| Flexion is the | Decrease in angle between 2 bones |
| Extension is the | Increase in angle between 2 bones |
| Lateral Flexion | Side bending |
| Abduction | Moves away from center of body |
| Adduction | Moves towards center of body |
| Rotation | Turns on an axis |
| Pronation | Palm down, turn downward |
| Supination | Palm up, turn upward |
| Eversion | Turn sole of foot outward |
| Inversion | Turn sole of foot inward |
| Curcumduction | Forms a circle |
| Dorsiflexion | Points foot and toes upward |
| Plantarflexion | Points foot and toes downward |
