The sternocostal joint is part of the shoulder girdle.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The sternocostal joint is not part of the shoulder girdle. It is actually a joint between the sternum and the ribs, and is responsible for allowing movement of the ribcage during breathing. The shoulder girdle, on the other hand, consists of the clavicle and scapula bones, which connect the upper limb to the axial skeleton. Therefore, the statement is false.Rate this question:

Acromioclavicular, sternocostal and glenohumeral
- B.
Sternochondral, sternoclavicular and acromioclavicular
- C.
Glenohumeral, manubriosternal and sternoclavicular
- D.
Acromioclavicular, sternoclavicular and glenohumeral
Correct Answer
D. Acromioclavicular, sternoclavicular and glenohumeralExplanation
The correct answer is acromioclavicular, sternoclavicular, and glenohumeral. These joints are all part of the shoulder girdle. The acromioclavicular joint is where the acromion process of the scapula meets the clavicle. The sternoclavicular joint is where the clavicle meets the sternum. The glenohumeral joint is the main joint of the shoulder, where the head of the humerus articulates with the glenoid fossa of the scapula. These three joints work together to provide movement and stability to the shoulder.Rate this question:
