Question

Because of a developmental defect, Joe is born without clavicles. As a result of this condition, you would expect

A) him to have less mobility at the shoulder joint.
B) him to have little use of his arms.
C) him to have an increased range of motion at the shoulder joint.
D) the humerus to not attach at the scapula.
E) a complete lack of mobility of the shoulder joint.

Answer 1

Being born without clavicles would lead to an increased range of motion at the shoulder joint, while potentially sacrificing strength and stability.

Step-by-step explanation:

The condition of being born without clavicles would result in an increased range of motion at the shoulder joint. The clavicles, also known as collarbones, serve as a connection between the shoulder blades (scapulae) and the sternum. Without clavicles, there would be less stability in the shoulder joint, allowing for greater freedom of movement. However, it is important to note that this increased range of motion may come at the cost of reduced strength and stability in the shoulder joint.
