QuestionAnswer
What is the name of the joint between the sternum and the clavicle?The Sternoclavicular Joint
What type of joint is the sternoclavicular joint?a saddle joint
How many ligament are found in the sternoclavicular joint?4 ligaments surround the joint - anterior and posterior sternoclavicular ligaments - interclavicular ligament - costoclavicular ligament
Name the structures1. Clavicle 2. Manubrium of the sternum
Name the structureArticular Disc
Name the structureanterior sternoclavicular ligament and joint capsule
Name the structureCostoclavicular ligament
Name the structureInterclavicular ligament
What movements does the Sternoclavicular joint allow?- elevation - depression - retraction - protraction - rotation
What type of joint is found at the shoulder?Glenohumeral Joint
Why does the Glenohumeral joint lack stabality?It is the most freely movable joint so its articular capsule is thin and loose
Where does the Glenohumeral joint gain its little stabilitymuscle tendons contribute to joint stability
What makes up the Glenohumeral Joint (or rotator cuff)?the rotator cuff is made up of 4 muscles and their associated tendons - subscapularis - supraspinatus - infraspinatus - teres minor
Name the structureCoracoacromial ligament
Name the structureSubacromial bursa
Name the structureCoracohumeral ligament
Name the structureTransverse humeral ligament
Name the structureSubscapular bursa
Name the structureArticular capsule supported by glenohumeral ligaments
What is the joint found at the elbow?elbow joint
What type of joint is the elbow joint?Hinge joint - articulation occurs between the trochlear notch of the ulna and the humerus
What movements are seen at the elbow joint?flexion and extension
What provides stability to the elbow joint?Tendons of the biceps and triceps brachii provide stability
Name the structuretendon of triceps muscle
Name the structureTendon of brachialis muscle
Name the structureRadial collateral ligament
Name the structureAnular ligament
Name the structureArticular capsule
Name the structureAnular ligament
Name the structureUlnar Collateral ligament
What type of joint is found at the hip joint?a ball and socket joint because the head of the femur articulates with acetabulum
What provides stability to the hip joint?Stability comes from the acetabulum and capsular ligaments Some stability is also produced from muscle tendons
Name the structureSynovial cavity
Name the structureArticular cartilage
Name the structureLigament of the head of the femur (ligmentum teres)
Name the structureArticular capsule
Name the structureIliofemoral ligament
Name the structureIschiofemoral ligament
Name the structureIliofemoral ligament
Name the structurePubofemoral ligament
What type of joint is the knee jointthe knee joint acts primarily as a hinge joint - it is the largest and most complex joint
What type of joint is the knee joint considered structurally?a compound and bicondyloid joint
What other joint is present at the knee?The femoropatellar joint shares the joint cavity with the knee
Name the structureSuprapatellar bursa
Name the structureTendon of quadriceps femoris
Name the StructurePatella
Name the structureSubcutaneous prepatellar bursa
Name the structureLateral Meniscus
Name the structureDeep infrapatellar bursa
Name the structurePatellar ligament
Name the structureAnterior Cruciate ligament
Name the structurePosterior Cruciate ligament
Name the structureArticular capsule
Explain the crossing of the ACL and PCL ligamentsthe anterior cruciate ligament comes from the femur, crosses, and attaches to the tibia end the posterior cruciate ligament comes from the tibia, cross, and attaches to the femur end
What portions of the knee joint are covered? which portions are not and why?the capsule of the knee joint overs the posterior and lateral pest of the nee but not the anterior aspect because the anterior region is covered by 3 ligaments for movement
What ligaments cover the anterior region of the knee joint?- patellar ligament - medial and lateral patellar retinacula
Name the structure1. Lateral Patellar retinaculum 2. Medial Patellar retinaculum
Name the structurePatellar ligament
Name the structures1. Fibular collateral ligament 2. Tibial collateral ligament
Name the structureArticular capsule
Name the structureOblique Popliteal ligament
Name the structureTibial collateral ligament
What does the Anterior Cruciate ligament prevent?The ACL prevents anterior sliding of the tibia
What does the Posterior Cruciate ligament prevent?The posterior cruciate ligament prevents forward sliding of the femur or backward displacement of the tibia
What occurs when the knee is fully extended?when the knee is fully extended the cruciate ligaments are taut and the knee is locked
