Exam 4: The Shoulder Girdle

The insertion of the levator scapulae muscle is on the transverse processes of the upper four cervical vertebrae.

The insertion of the serratus anterior muscle is on the anterior aspect of the whole length of the medial border of the scapula.

The scapula moves on the rib cage as a consequence of joint motion actually occurring at the acromioclavicular joint and to a lesser extent at the sternoclavicular joint.

The origin of the serratus anterior muscle is the surface of the upper seven ribs at the side of the chest.

Which of the following muscles concentrically performs both elevation and depression?

The coracoclavicular ligament is particularly important in providing stability to the acromioclavicular joint.

Which of the following actions is performed concentrically by the levator scapulae muscle?

The origin of the rhomboid muscles is the spinous processes of the last cervical and the first seven thoracic vertebrae.

Which of the following muscles has its origin in the surface of the upper nine ribs at the side of the chest?

Which of the following muscles would best be strengthened by the bench press and overhead press exercises?

Which of the following muscles is innervated by the spinal accessory nerve and branches of C3 and C4?

The trapezius muscles can cause adduction in a transverse plane of motion when contracting eccentrically.

Which of the following is a salient feature of the upper fibers of the trapezius muscle?

The origin of the subclavius muscle is the superior aspect of the first rib at its junction with its costal cartilage.

In the context of shoulder girdle movements, which of the following terms refers to the movement of the scapula medially toward the spinal column, as in pinching the shoulder blades together?

The pectoralis minor muscle is innervated by the:

The origin of the pectoralis major muscle is the anterior surfaces of the third to fifth ribs.

Which of the following muscles are used powerfully in the lifting phase of chinning, an activity in which an individual hangs from a horizontal bar suspended by his or her hands and pulls himself or herself up until his or her chin is over the bar?

The concentric actions of the serratus anterior muscle include scapula abduction and upward rotation.

The pectoralis minor muscle can perform adduction, downward rotation, or depression when contracting concentrically.
