To increase the angle of a joint is extension. To decrease the angle of a joint is flexion. (plato users the answer is A.)
The trapezius muscle in humans is a single, large muscle divided into three specific regions based on their functions: the upper trapezius, middle trapezius, and lower trapezius. Each region of the trapezius muscle contributes to different movements of the shoulder and neck.
Yes, the trapezius muscle is commonly referred to as the traps.
The synergist of the trapezius in scapular elevation is the levator scapulae muscle. It works together with the trapezius to elevate the scapula and assist in movements like shrugging the shoulders.
Trapezius muscle- located from the skull through the cervical and thoracic vertebrae to the lateral 1/3 of the clavicle and spine of scapula. Function: Elevates, Depresses, Retracts, and rotates the scapula up and down. Innervated by the Spinal Accessory Nerve

The lower trapezius muscle helps stabilize and move the shoulder blades, supporting proper posture and shoulder movement.
To increase the angle of a joint is extension. To decrease the angle of a joint is flexion. (plato users the answer is A.)

No, the trapezius is not a smooth muscle; it is a skeletal muscle. Skeletal muscles, like the trapezius, are under voluntary control and are responsible for movements of the head, neck, and shoulders. In contrast, smooth muscles are involuntary and are found in structures like blood vessels and the digestive tract. The trapezius plays a key role in posture and movement, particularly in shrugging the shoulders and tilting the head.
No, the trapezius is not an abductor. It is a large muscle that extends from the back of the neck down to the mid-back and across the shoulders. Its primary functions include stabilizing, raising, and retracting the scapula, as well as extending the neck. Abduction typically refers to the movement of limbs away from the body's midline, which is not a primary role of the trapezius.

When the angle of a joint increases, it produces a movement called "extension." This movement typically occurs in joints such as the knee or elbow, where the angle between the two bones becomes larger. Extension is the opposite of flexion, which decreases the angle between the bones at a joint.
