Structure of selected synovial joints Flashcards
Shoulder joint (glenohumeral joint)
Most flexible, least stable
Glenoid fossa of scapula
Shallow articular socket, glenoid labrum
Shoulder dislocation
Separation of glenohumeral joint
Shoulder separation
Damage to acromioclavicular joint or clavicle
Ligaments of shoulder
Coracohumeral, glenohumeral coracoacromial, acromioclavicular
Muscle tendons of the shoulder
Biceps brachii and rotator cuff
Biceps brachii
2 headed muscle, long head originates at top of glenoid cavity
Rotator cuff
4 muscles
supraspinatus, infraspinatus, and teres minor all are at the back
subscapularis=front
Elbow joint
hinge joint that has ligaments on both sides
Radial collateral ligament
connects humerus to radius and ulna=lateral
Ulnar collateral ligament
Does not attach to radius=medial
Hip (Acatabulofemoral joint)
has Acetabular labrum and a joint capsule covers the entire thing
Iliofemoral ligament
Connects ilium to femur
Knee joint
largest joint in the body
Meniscii
Give padding
Medial meniscus
Is thicker than the lateral meniscus
Patellar ligament
Patella to tibia
Medial collateral ligament (MCL)
Is medial
Lateral collateral ligament (LCL)
Is lateral
Anterior cruciate ligament (ACL)
Is anterior and crosses in the front
Posterior cruciate ligament (PCL)
Is posterior and crosses in the back
Bursitis
Inflammation of bursa
Tendonitis
Inflammation of tendon sheaths
Osteo arthritis
Is degenerative, due to wear and tear of the joints with advancing age or overuse
Rheumatoid arthritis
autoimmune disorder
