Chapter 9 Shoulder Girdle

PRE-LAB WORKSHEETS
1. In the table, indicate which bones make up each of the structures.
Structures Scapula Clavicle Sternum Ribcage Humerus
Shoulder complex X X X X X
Scapulothoracic articulation X X
Shoulder girdle X X
Shoulder joint X X
2. Define the terms that follow.
Scapulohumeral rhythm: Describes movement relationship between shoulder girdle and shoulder joint.
Reversal of muscle action: With the insertion of a muscle stabilized, the origin moves toward the insertion.
3. Enter the letter by the structures in Figures 9-1 to 9-3 next to the correct label for that structure. You can also write the names of the structures on the figures.
Scapula: D Acromion process B Axillary border
E Coracoid process C Glenoid fossa
A Inferior angle H Spine
G Superior angle F Vertebral border
Clavicle: C Acromion end B Body
A Sternal end
Sternum: E Body D Manubrium
G Sternal notch F Xiphoid process
Skull: A Occipital
protuberance
Vertebra: C Spinous process B Transverse
process
FIGURE 9-1 Landmarks of the scapula.

FIGURE 9-3 Landmarks of the skull and cervical spine.
FIGURE 9-2 Landmarks of the clavicle and sternum.
4. Enter the letter by the structures in Figure 9-4, A and B next to the correct label for that structure. You can also write the names of the structures on the figures. A. Identify the joints and bones.
Bones: E Acromion D Clavicle
G Coracoid process A Ribs
H Scapula C Sternum
Joints: B Acromioclavicular F Sternoclavicular
B. Identify the structures that follow.
B Acromioclavicular L Coracoclavicular ligament ligament
I Articular disk K Costoclavicular
ligament
J Coracoacromial M Sternoclavicular ligament ligament

FIGURE 9-4 Bones, joints, and ligaments of the shoulder girdle.
5. On Figures 9-5 through 9-8:
A. Using your own words, enter the origins and insertions of the muscles listed in the table.
Figure and Muscle Origin Insertion
Figure 9-5 Upper trapezius Occipital bone, nuchal ligament Outer third of clavicle, acromion on upper cervical spinous processes process
Figure 9-5 Middle trapezius Spinous processes of C7 through T3 Scapular spine
Figure 9-5 Lower trapezius Spinous processes of middle and Base of the scapular spine lower thoracic vertebra
Figure 9-6 Levator scapula Transverse processes of first four Vertebral border of scapula between cervical vertebrae the superior angle and spine
Figure 9-6 Rhomboids Spinous processes of C7 through T5 Vertebra retraction, elevation, and downward rotation
Figure 9-7 Serratus anterior Lateral surface of the upper eight ribs Vertebral border of the scapula, anterior surface
Figure 9-8 Pectoralis minor Anterior surface, third through fifth ribs Coracoid process of the scapula

B. Label the origin and insertion of the muscle(s) listed. Color the origin in red and the insertion in blue.
Join the origin and insertion to show the
