Identify the choice that best completes the statement or answers the question.

____ 1. The primary purpose of the shoulder complex is to:

____ 2. The shoulder complex as a whole primarily relies on ___________ for stability.

____ 3. The shoulder complex is attached to the axioskeleton at which joint?

____ 4. The glenoid labrum adds approximately _____ % more surface area to the depth and curve of the glenoid fossa.

____ 5. Relative to the distal humeral condyles, the humeral head is rotated _________ in the ___________ plane.

____ 6. Motion at the scapulothoracic joint is a result of combined motion from which joint(s)?

____ 7. Medial and lateral tilting of the scapula occurs about a(n) _________ axis.

____ 8. As the arm is elevated in the scapular plane (particularly during higher angles of elevation), which combination of tilts at the scapula occur?

____ 9. Which motions of the scapula occur when an individual places his or her upper extremity behind his or her back (functional medial rotation)?

____ 10. How many degree(s) of angular freedom are present at the sternoclavicular joint?

____ 11. During protraction at the sternoclavicular joint, the ___________ clavicle glides ____________ on the sternum.

____ 12. Tension in this ligament facilitates posterior rotation of the clavicle during elevation of the upper extremity:

____ 13. The sternoclavicular joint is classified as a _______________ joint.

____ 14. Elevation at the sternoclavicular joint takes place between:

____ 15. The acromioclavicular joint is classified as a ___________ joint.

____ 16. The acromioclavicular joint is thought to contribute approximately _________° to upward rotation of the scapula.

____ 17. The scapulothoracic joint is classified as a _____________ joint.

____ 18. Protraction of the sternoclavicular joint occurs in the _____________ plane.

____ 19. Upward rotation of the scapula occurs primarily about a(n) ____________ axis.

____ 20. On average during elevation of the arm, a ____ ratio of glenohumeral to scapular motion exists.

____ 21. The glenohumeral joint is classified as a ___________ joint.

____ 22. The humeral head is approximately _____ times the size of the glenoid fossa.

____ 23. Which ligament is primarily responsible to resist gravity’s downward pull on the humeral head with the arm in the resting position?

____ 24. The tendon of the long head of the biceps is considered to be:

____ 25. A strong contraction of the biceps with the elbow flexed and shoulder abducted to 90°, promotes _________ and prevents _________ translation of the glenohumeral joint.

____ 26. Which of the following is a structural cause of subacromial impingement syndrome?

____ 27. The anterior capsule of the glenohumeral joint becomes taut with extreme ___________ and ___________.

____ 28. The normal limitation or “end feel” for all motions of the glenohumeral joint is:

____ 29. During lateral rotation of the glenohumeral joint, the humerus rolls _________ and glides or slides __________.

True/False

Indicate whether the statement is true or false.

____ 30. The glenoid fossa’s alignment is tipped a few degrees inferior relative to the scapula’s vertebral border.

____ 31. Anterior tilting of the scapula occurs when the superior border of the scapula tilts forward with its inferior angle moving away from the thorax.

____ 32. The majority of clavicular elevation occurs in the second 90° of humeral elevation.

____ 33. With the upper extremities in a closed kinetic chain, depression of the scapula will cause elevation of the trunk and body.

____ 34. During scapular elevation, small adjustments at the acromioclavicular joint allow the vertebral border of the scapula to remain essentially vertical in alignment.

____ 35. During abduction, the humerus must rotate medially so the greater tuberosity can “clear” the acromion.

____ 36. Lateral rotation of the glenohumeral joint is greater at 90° of abduction compared with when the arm is at 0° of abduction (resting by the side).

____ 37. The resting or loose packed position of the glenohumeral joint is full abduction and lateral rotation.

____ 38. During upward rotation of the scapula, the axis of rotation of the scapula migrates laterally.

____ 39. As the upper extremity progresses to higher levels of elevation, the moment arm for the lower trapezius to upwardly rotate the scapula becomes larger.

____ 40. The deltoid muscle is essential to fully abduct the arm.
