G.A. arthrology & syndesmosis Flashcards
Synarthrosis? examples?
immoveable
Sutures: parietal bones of the skull, hard palate
Gomphoses: teeth, styloid process in temporal bone
Synchondroses: epiphyseal plate
Amphiarthrosis? examples
slightly moveable
Syndesmosis: beween shafts of distal ulna & radius, distal art. tibia & fibula
Symphysis: pubis symphysis, IVD (both are fibrocartilage)
Diarthrosis? examples?
synovial joints- freely moveable
hinge: ginglymus- knee,, elbow, phalanges, TMJ
Pivot: Trochoid- atlas & axis, prox. radioulnar
Gliding: between carpals & tarsals, sternoclavicular & costovertebral joints
Saddle: Sella- thumb
Ellipsoidal: condyloid- radiocarpal, atlanto-occipital
Ball & Socket: spheroid- hip, shoulder
Fibrous structural class?
Sutures- skull
gomphoses- teeth
syndesmoses- art between radius & ulna
Cartilaginous structural class?
synchondroses- epiphyseal plates (hyaline cart.)
Symphysis- pubis symphysis (fibrocartilage)
ligamentous & synovial joints structural class
hinge, pivot, gliding, ellipsoidal, saddle, ball & socket
Shoulder Ligaments
- Articular capsule- rim of glenoid fossa to humerus
ant. support of capsule- coracohumeral, glenohumeral - acromioclavicular- AC joint- acromion to clavicle
- Coracoclavicular- coracoid to clavicle
- coracoacromial- coracoid to acromion
- Glenoid labrum- rim of fibrocart. around glenoid fossa
Elbow Ligaments
- Ulnar collateral- med. epicondyle to between the olecranon process & coronoid process
- radial coll.- lat. epi. to lateral ulna
Sprain?
ligament damage- PASSIVE
Strain?
Muscle/tendon damage- TENDON
Knee Ligaments
- Patellar lig.- patella to inf. tibial tuberosity
- Med. & Lat. Coll.- med. epi to tibial shaft; lat epi to head of fibula
- lat & med meniscus- externally to condyles of tibia
- anterior cruciate- ant. intercondylar of tibis to posteromedial surface of lat condyle
- post. cruciate- post intercondylar to femur on lat side of med condyle
Unhappy Triad is?
Medial meniscus
Ant. cruciate
Medial coll.
“MAM”
Hip Ligaments
iliofemoral
acetabular labrum
ischiofemoral
pubofemoral
Ankle & foot Ligaments
Deltoid- tibiotalar, tibionavicular, tibiocalcaneus “strongest ligament” medial malleolus to tarsus
Lateral Lig.- ant. talofibular, post talofibular, calcaneofibular; lateral malleolus to tarsus
Spring Ligament
aka plantar calcaneonavicular
sustentaculum tail to navicular
maintains longitudinal arch
