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 structures | 1. Clavicle
2. Manubrium of the sternum |
Name the structure | Articular Disc |
Name the structure | anterior sternoclavicular ligament and joint capsule |
Name the structure | Costoclavicular ligament |
Name the structure | Interclavicular 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 stability | muscle 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 structure | Coracoacromial ligament |
Name the structure | Subacromial bursa |
Name the structure | Coracohumeral ligament |
Name the structure | Transverse humeral ligament |
Name the structure | Subscapular bursa |
Name the structure | Articular 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 structure | tendon of triceps muscle |
Name the structure | Tendon of brachialis muscle |
Name the structure | Radial collateral ligament |
Name the structure | Anular ligament |
Name the structure | Articular capsule |
Name the structure | Anular ligament |
Name the structure | Ulnar 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 structure | Synovial cavity |
Name the structure | Articular cartilage |
Name the structure | Ligament of the head of the femur (ligmentum teres) |
Name the structure | Articular capsule |
Name the structure | Iliofemoral ligament |
Name the structure | Ischiofemoral ligament |
Name the structure | Iliofemoral ligament |
Name the structure | Pubofemoral ligament |
What type of joint is the knee joint | the 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 structure | Suprapatellar bursa |
Name the structure | Tendon of quadriceps femoris |
Name the Structure | Patella |
Name the structure | Subcutaneous prepatellar bursa |
Name the structure | Lateral Meniscus |
Name the structure | Deep infrapatellar bursa |
Name the structure | Patellar ligament |
Name the structure | Anterior Cruciate ligament |
Name the structure | Posterior Cruciate ligament |
Name the structure | Articular capsule |
Explain the crossing of the ACL and PCL ligaments | the 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 structure | 1. Lateral Patellar retinaculum
2. Medial Patellar retinaculum |
Name the structure | Patellar ligament |
Name the structures | 1. Fibular collateral ligament
2. Tibial collateral ligament |
Name the structure | Articular capsule |
Name the structure | Oblique Popliteal ligament |
Name the structure | Tibial 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 |
