Multiple Choice 10 points Which of the following bones of the shoulder girdle is the most commonly fractured? Humerus Clavicle Scapula Sternum Multiple Choice 10 points Which of the following planes of motion includes flexion and extension? Transverse Frontal Sagittal Glenohumeral

Question 1:<br />Which of the following bones of the shoulder girdle is the most commonly fractured?<br />A. Humerus<br />B. Clavicle<br />C. Scapula<br />D. Sternum<br /><br />Answer: B. Clavicle<br /><br />Explanation: The clavicle the most commonly fractured bone in the shoulder girdle. It is a long, slender bone that connects the sternum (breastbone) to the scapula (shoulder blade). The clavicle is relatively weak and vulnerable to fractures, especially during falls or direct blows to the shoulder area.<br /><br />Question 2:<br />Which of the following planes of motion includes flexion and extension?<br />A. Transverse<br />B. Frontal<br />C. Sagittal<br />D. Glenohumeral<br /><br />Answer: C. Sagittal<br /><br />Explanation: The sagittal plane is one of the three main planes of motion in the human body. It divides the body into left and right halves. Flexion and extension movements occur in the sagittal plane. Flexion refers to the bending or decreasing angle between two body parts, while extension refers to the straightening or increasing angle between them. The sagittal plane allows for these forward and backward movements of the limbs and trunk.
