The Shoulder Girdle/Joint

Lab 4 KINE 3300 Applied Kinesiology

When the student completes this lab, he/she should be able to:

1. Identify on a skeleton or human subject the structures of the shoulder 2. Draw on a skeleton chart, using arrows, the shoulder joint movements 3. Determine the list of movements and list the agonists and their antagonists

Lab activities:

1-from which joint is the shoulder connected to spinal column? a-acromioclavicular joint. b-scapulothorasic joint. c-glenohumeral joint. d-sternoclavicular joint.

2-which of the following joint is not a part of shoulder complex? a-scapulothorasic. b-sternoclavicular. c-atlato-axial. d-acromioclavicular.

3-where is the insertion of pectoralis minor? a-Acromian process. b-Corracoid process of scapula. c-medial border of scapula. d-spine of scapula.

4-what is the function of levator scapulae muscle? a-flexion of shoulder. b-abduction of scalpula. c-adduction of scapula. d-elevation of scapula. 5-Draw diagram representing all the movement of shoulder joint and name the plane and axis of each movement.

6-Palpate sternoclavicular joint on a subject. Describe its location in reference to the most lateral edge of the deltoid muscle.

7-which nerve innervates rhomboid muscle. a-spinal accessory. b-long thoracic. c-dorsal scapula nerve. d-medial pectoral nerve.

8-From which cord does musculocutaneous nerve originate? a-lateral cord. b-posterior cord. c-medial cord. d-None of these.

9-In which part of scapula does the humeral head fit, to make glenohumeral joint? a-acromian process. b-coracoid process. c-glenoid cavity. d-spine of scapula. 10-Label the figure using the list given below.

(A) Coracoid Process (B) Superior Margin (C) Scapular Spine (D) Vertebral Margin (E). Axillary Margin (F) Glenoid Cavity Margin (G) Acromion Process (H) Infraspinatus Fossa (I) Inferior Angle ( J) Scapular notch (k) Superior angle ( L) Supraspinatus fossa.

11- Deltoid muscle is a. an elevator of the scapula. b. a developmentally dorsal muscle. c. the prime mover for flexion of the glenohumeral joint. d. the main adductor of the shoulder joint. 12-If long thoracic nerve gets injured then which movement of shoulder girdle will be affected. a-downward rotation. b-elevation. c-adduction. d-abduction.

13-Subclavius muscle can be strengthened by. a-active elevation. b-avtive depression. c-active addution. d-active flexion.

14-The origin of rhomboid muscle is spineous process of a- C2 to C7 b- C3 to C6 c- C1 to C5 d- C7 to T5

15-Do wall pushups and analyze the movement taking place in scapula. 16-

16-In the above figure label the number 1,2,3,4,5,6.

17-If a person gets a blow on medial end of clavicle then which ligaments are likely to be injured.
