| Slightly movable | Amphiarthrosis is what kind of joint? |
| Freely moveable | Diarthrosis is what kind of joint? |
| Fibrous Cartilaginous Synovial | Three STRUCTURAL classifications of joints |
| No joint cavity; bones held by CT Sutures hold together with thin dense CT Synarthrotic in adults and amphiarthrotic in children | FIBROUS sutures is held together by what? Syn, Amph, or Diar? |
| More fibrous CT than in suture; fibrous CT forms n INTEROSSEUS membrane or ligament Amphiarthrotic Interosseus membrane between radius and ulna & tibia and fibia | FIBROUS Syndesmosis is held together by what? Syn, Amph, or Diar? EX? |
| Syndesmosis (pegs teeth into sockets; alveoli) Synarthrotic | FIBROUS gomphosis is what kind of special joint? Syn, Amphi, or diar? |
| Cartilage (no joint cavity) | Cartilaginous joints are connected by what? |
| Synchondrosis Symphysis | 2 types of cartilaginous joints |
| Hyaline cartilage | Cartilaginous synchondrosis is what kind of cartilage? |
| Epiphyseal plate: connects diaphysis and epiphysis; synarthrotic Costal cartilage: connects rib to sternum; amphiarthrotic | Cartilaginous synchondrosis Examples and Syn, amphi, or diar? |
| Space articulating between bones freely moveable diarthrotic | What is synovial? Syn, amphi, or diar? |
| 1. consistency of egg white 2. lubricates joint 3. Nourishes articular cartilage 4. Contains phagocytic cells to remove debris from joint | Synovial membrane 4 classifications |
| Hyaline cartilage that covers ends of bones but does not bind bone together | Articular cartilage definition |
| Sac lined with synovial membrane that reduces friction between body parts; found between skin and bone, tendons and bones, muscle and bone, ligaments and bone | Bursa definition and found where? |
| Synovial membrane wrapped like a hot dog bun that completely wraps around a TENDON | Tendon Sheath definition |
| 1. Occurs only between bones of skull 2. Rigid slices that knot the skill bones together yet allow skull to expand as a child grows 3. Synarthrotic in adults | Describe 3 structure and degree of movement of a suture and their location in the body |
| 1. Connected by ligaments or cords of fibrous tissue 2. Amphiarthrotic 3. Ulna and radius | Describe the structure and degree of movement of syndesmosis joints in the body and give examples (3 points) |
| 1. Only found in our teeth that fit in areolar socket 2. Synarthrotic | Describe the structure and degree of movement of gomphosis joints and give example |
| Pubic symphysis: amphiarthrotic Intervertebral Disc: amphiarthrotic | Cartilaginous Symphysis examples |
| Hyaline cartilage unites bone; Synarthrotic, costal cartilage, epiphyseal plate | Structure and degree of movement of synchondrosis and give example. Cartilage? |
| Amphiarthrotic; fibrocartilage unites bone; pubic symphysis, intervertebral discs | Structure and degree of movement of symphysis joints and example. Cartilage? |
| 1. Tough external FIBROUS LEVEL composed of dense irregular CT (strengthens bone) 2. Inner layer is SYNOVIAL MEMBRANE composed of loose CT (makes synovial fluid) | Structure and function of articular capsule (2 points) |
| Inter carpal and inter tarsal, sternoclavicular, acromioclavicular, sternocostal, vertebrocostal (slide past each other) | Structural features of Planar synovial joints |
| Knee, elbow, ankle, and interphalangeal (flexion and tension) (joints between fingers) | Structural features of Hinge synovial joints |

| Carpometacarpal in thumb (2 axis rotation) | Structural features of Saddle synovial joint |
| Shoulder and hip (multiaxial; femur to pelvis, scapula to humerus | Structural features of Ball and Socket synovial joint |
| Planar EX: carpal bones of wrist | Gliding movement |
| Head, arms, legs (flexing is bending) | Flexion and Extension movement |
| Intervertebral joints; head upper body swaying | Lateral Flexion Movement |

| Broad flat ligament that connects medial condyle of femur to medial condyle of tibia Connects to medial meniscus | Medial collateral ligament |
| Rounded ligament on the lateral surface joint that extends from lateral condyle of femur to the lateral side of fibula DOES NOT CONNECT TO LATERAL MENISCUS | Lateral Collateral ligament |
| Originates anterior to intercondylar eminence of tibia and extends posterior and laterally to medial side of lateral condyle of femur | Anterior Cruciate Ligament (ACL) |
| Originates on posterior intercondylar area of tibia and extends anteriorly and medially to the medial surface of the medial condyle of the femur | Posterior Cruciate Ligament (PCL) |
| 1. Collateral ligaments 2. Cruciate ligaments 3. Cartilages (meniscus) | Common three knee injuries |
| Tears tibial collateral ligament and the medial meniscus attached to it as well as the ACL | What is a lateral blow? |
