The shoulder is a complex of what four independent articulations?
Sternoclavicular joint
Acromioclavicular joint
Glenohumeral joint
__________ joint is a ball and socket joint formed by the head of the humerus and the glenoid cavity of the scapula
Glenohumeral joint (shoulder joint)
_________ thin, loose sac that extends from the glenoid cavity to the anatomical neck of the humerus, the inferior part is its weakest area
Articular capsule
__________ _________, strong, broad ligament that strengthens the superior part of the articular capsule and extends from the coracoid process of the scapula to the greater tubercle of the humerus
Coracohumeral ligament
_________ __________ are three thickening fo the articular capsule over the anterior surface of the joint that extend from the glenoid caivty to the lesser tubercle and anatomical neck of the humerus.
Glenohumeral ligaments
___________ _______ play a role in joint stabilization of the shoulder
Glenohumeral ligaments
________ ______ narrow rim of fibrocartilage around the edge of the glenoid cavity that slightly deepens and enlarges the glenoid cavity
Glenoid labrum
Four __________ are associated with the shoulder joint
Bursae
The four bursae are:
Subscapular bursa
Subdeltoid bursa,
Subacromial bursa
Subcoracoid bursa
Most stability of the shoulder joint results from the arrangements of the _______ muscles
Rotator cuff muscles
What are the rotator cuff muscles
Supraspinatus, infraspinatus, teres minor, and subscapularis
What anchors the humerus to the scapula?
The rotator cuff muscles
The elbow joint is a _______ joint formed by the _______ and _________ of the humerus, the _______ of the ulna and the _______ of the radius
Hinge joint
Trochlea and capitulum

The trochlear notch of the ulna and the head of the radius
The elbow joint has an articular capsule. The anterior part of the articular capsule covers what?
The anterior part of the elbow joint from the radial and coronoid fossa of the humerus to the coronoid process of the ulna and the ulna posterior to the radial notch
The elbow joint allows what movement?
Flexion and extension of the forearm
What forms the hip joint and what type of joint is it?
Ball and socket joint formed by the head of the femurs and the acetabulum of the hip bone

Circumduciton of the thigh
What makes the hip joint extremely stable?
Very strong articular capsule and its accessory ligaments
The manner in which the femur fits into the acetabulum
The muscles surrounding the joint

Knee joint
_______ is a modified hinge joint that consists of 3 joints within a single synovial cavity
Knee joint
What are the three joints in the knee joint
Lateral Tibiofemoral
Medial tibiofemoral joint
Intermediate patellofemoral joint
What are the 3 important bursae of the knee?
Prepatellar bursa (between the patella and skin) Infrapatellar bursa (between the superior part of the tibia and patellar ligament) Suprapatellar bursa (between inferior part of femur and deep surface of quadriceps femoris muscle
What movements does the knee joint allow?
Flexion, extension
Slight medial rotation
Lateral rotation of the leg in flexed position
