What movement occurs when the shoulder is moved in a circular motion?

• A. Flexion
• B. Rotation
• C. Circumduction
• D. Abduction

Answer: (C)

The movement that occurs when the shoulder is moved in a circular motion is known as circumduction. This term specifically refers to a conical movement where the extremity describes a circle, combining the motions of flexion, extension, abduction, and adduction. When the shoulder undergoes circumduction, it can be visualized as a circular path traced by the arm, which enables a wide range of motion. This is particularly relevant in activities such as swimming or throwing, where the arm moves in a circular trajectory. Other movements mentioned, such as flexion and abduction, represent different types of movements. Flexion refers to decreasing the angle between two body parts, while abduction involves moving a limb away from the midline of the body. Rotation, on the other hand, indicates turning around an axis, which does not fully encapsulate the compound circular motion described by circumduction. Thus, circumduction is the most accurate term for the described movement of the shoulder in a circular manner.
