Does the insertion normally move towards the origin, or does the origin normally move towards the insertion? How do we identify the SCM origin and insertion? How do those relate to the actions of the SCM? Describe the origin and insertion of the pectoralis major and how they relate to function/motion 2. Innervation is:

Tennis elbow (lateral epicondylitis) is Due to repetitive microtraumas. O More common than medial epicondylitis. O Often involves injury to the extensor carpi radialis brevis muscle. All of the above Question 5

The pectoralis major can do which of the following movements at the shoulder? Group of answer choices External rotation Horizontal adduction All of these Horizontal abduction

Which of these increases force production? 1. Increasing the velocity of the concentric contraction 2. Increasing the velocity of the eccentric contraction 3. Increasing strength of neural stimulation 4. Holding your breath during contraction 5. Increasing frequency of neural stimulation 6. Decreasing the velocity of the concentric contraction 7. Starting the contraction with the joint in full extension 8. Decreasing the velocity of the eccentric contraction

To do Right shoulder abduction – A24 in the frontal plane, the (muscle) would have to lie (A – Where?) relative to the joint, and since it can only (B          ), the fibers would have to run (C                    ) to the (D                  ) axis to achieve the desired movement. choose from: A. Pick from: Anterior, Posterior, Medial, Lateral, Superior, Inferior B. Write in the word “PULL”    C. Write “perpendicular”  D. Pick from :Anterior - posterior, Superior-inferior or Medio - Lateral

A 20-year-old man complained that he was unable to raise his right upper limb.  He held it limply at his side with his forearm and hand pronated.  During questioning by the physician, he stated that he had been thrown from his motorcycle approximately 2 weeks previously and that he had hit his shoulder against a tree.  He also recalled that his neck felt sore shortly after the accident.   Physical Examination: On examination it was found that the patient was unable to flex, abduct, or laterally rotate his arm.  In addition, he lost flexion of the elbow joint. A lack of sensation was detected on the lateral surface of his arm and forearm.  The physician requested radiographs of the cervical and pectoral girdle regions.   Radiology Report: No fractures are seen in the cervical region, pectoral girdle, and proximal part of the humerus.   Diagnosis: Injury of nerves derived from the brachial plexus.     Using your anatomical knowledge of the nerve supply to the upper limb, discuss the…

What is the function and structure of the TMJ (Temporomandibular joint) including normal arthrokinematics motions, muscle action, and the problems associated with disk location. What does a “click” mean on opening or closing?

Which of the following is the prime mover for shoulder flexion? Group of answer choices Anterior deltoid Posterior deltoid Coracobrachialis Long head of the triceps
