11. Note the conoid tubercle on the inferior, lateral end of the clavicle that serves as an attachment site for several ligaments. Superior view Inferior view
12. Master Long is going to easily fracture his opponent’s right clavicle so his opponent will be unable to use that arm.
13. ACCORDING TO THE CLINICAL VIEW IN YOUR TEXT, WHY IS A POSTERIOR FRACTURE OF THE CLAVICLE POTENTIALLY MORE SERIOUS THAN AN ANTERIOR FRACTURE? A MORE LIKELY TO BREAK THE SKIN B MORE LIKELY TO DAMAGE BLOOD VESSELS C MORE LIKELY TO ENTER HEART D MORE LIKELY TO INJURE ULNAR NERVE E MORE LIKELY TO TEAR DIAPHRAGM
14. The scapula normally lays over ribs #2-#7 on the posterior aspect of the rib cage.
20. The humerus is the longest bone of the upper extremity. groove
21. The distal end of the humerus is modified to articulate with the two bones of the forearm.
22.
23. The radial fossa accommodates the head of the radius and the coronoid fossa of the humerus receives the coronoid process of the ulna when the elbow is flexed. Anterior view
24. The olecranon fossa of the humerus receives the olecranon of the ulna when the elbow is extended Posterior view
25. WHICH OF THE FOLLOWING IS CORRECT ABOUT THE DISTAL MEDIAL END OF THE HUMERUS? A NEAR THE ULNAR NERVE B SHAPED LIKE A PULLEY C ARTICULATES WITH THE ULNA D FORMS A FIRM HINGE JOINT WITH THE FOREARM E ALL OF THE ABOVE
27. Note the head of the radius and the radial notch in nearby ulna
28. The radius is lateral to the ulna. Note the head , neck , the radial tuberosity , the shaft , and the styloid process on the lateral tip. Trochlear notch
29. Note styloid processes on distal radius and ulna and ulnar notch on medial distal end of the radius
30. The proximal end of the ulna forms the trochlear notch . Note the anterior coronoid process and the posterior olecranon . The radial notch , mentioned earlier, accommodates the nearby head of the radius
31. The distal end of the ulna is called the head . It has a medial projection called the styloid process . The distal ulna also once again articulates with the nearby radius. Trochlear notch
32. The styloid processes of the distal ulna and radius create a “U-shaped” arrangement to help stabilize the bones of the wrist.
33. The interosseous membrane helps keep the radius and ulna a fixed distance from one another and also allows rotation of the forearm.
35. Crucifixion is properly performed in the wrist or between distal ends of radius and ulna
36. The Governor of California shown properly crucified with nails in wrist or between distal end of radius and ulna. Note the vulture perched on arm that is soon to be lunch.
50. WHAT BONE IS ENCIRCLED BY A WEDDING RING? A METACARPAL #3 OF RIGHT HAND B PROXIMAL BONE OF POLLEX C DISTAL PHALANX OF FINGER #5 OF RIGHT HAND D BONE MEDIAL TO METACARPAL #4 AND MIDDLE PHALANX #4 E MIDDLE PHALANX OF FINGER #3 OF LEFT HAND
51. One of many ways to fracture the delicate clavicle .
79. A child who lived next door to me did this by falling off the trampoline
80.
81. Colles’fracture. Fracture of the distal end of the radius causing a “silver fork” deformity.
82. Fracture of the distal end of the radius results in a characteristic “silver fork” deformity. This type of fracture is called a Colles’ fracture .
83. IF YOU WERE LAYING IN THE PARK PROPPED UP BY ONE FULLY EXTENDED ARM AND A HEAVY CHILD RAN INTO THE POSTERIOR OF THIS SAME EXTENDED ARM, WHAT WOULD MOST LIKELY OCCUR ? A FRACTURE OF THE OLECRANON B A-C SEPARATION C COLLES FRACTURE D SCAPULAR FRACTURE E FRACTURE OF A SESAMOID BONE
