True or False: The Trapezius muscle inserts on the acromion process and spine of the scapula while originating from all 12 thoracic vertebrae.

True or False: The Trapezius muscle inserts on the acromion process and spine of the scapula while originating from all 12 thoracic vertebrae.

• A. True
• B. False

Answer: (A)

The statement is true because the Trapezius muscle does indeed insert on both the acromion process and the spine of the scapula. Its role includes stabilizing the scapula and aiding in shoulder movements, which is facilitated by its attachment to these specific anatomical structures. The origin of the Trapezius muscle is more extensive than just the thoracic vertebrae; it originates from the external occipital protuberance of the skull, the nuchal ligament, and the spinous processes of all 12 thoracic vertebrae. This broad origin allows it to have a wide range of motion and contribute to various movements of the neck and shoulders. Therefore, considering both the correct insertion points and the comprehensive origin, the statement accurately describes the anatomy and function of the Trapezius muscle, justifying that the answer is true.
