THE UPPER EXTREMITY
DO NOW
• List as many muscles in the arm as you can
HOMEWORK REVIEW
• Clear your desk• 1 Question quiz
• What is the fleshy muscle of the arm that is a favorite for intramuscular injections (shots)?• Write on piece of paper with name and pass it in
HOMEWORK
• Create Flashcards for the following muscles• Triceps Brachii• Brachialis• Brachioradialis• Pronator Teres• Extensor Carpi Radialis• Extensor Carpi Ulnaris
REVIEW
REVIEW
• Deltoid• Pectoralis Major• Biceps Brachii• Rotator Cuff• Supraspinatus• Infraspinatus• Subscapularis• Teres Minor
INJURIES OF THE SHOULDER
• Biceps Tondonitis• Shoulder Impingement
BICEPS TENDONITIS
• Overuse of the biceps• Opposite of overuse?
• 2 origins of the bicep• Coracoid process• Glenoid tubercle
• Very common in swimmers, pitchers
SHOULDER IMPINGEMENT
• Commonly, an overuse injury• Muscles inflame in the shoulder and not enough
space is allowed for muscles to swell• Compress the nerve
• Sometimes it is a structural abnormality• Acromion Process hooks downward to close space
SHOULDER IMPINGEMENT
SHOULDER IMPINGEMENT
THE ELBOW/FOREARM
ELBOW/FOREARM
• All “flexors” are palmar side of arm • Forearm
• Extensors are opposite and on the dorsal side of the forearm
TRICEPS BRACHII
• O: Glenoid Cavity of Scapula• I: Olecranon process of ulna• A: Forearm extensor; antagonist of biceps brachii
TRICEPS BRACHII
BRACHIALIS
• O: Anterior surface of distal humerus• I: Coronoid process of ulna• A: Arm flexor
BRACHIALIS
BRACHIORADIALIS
• O: Distal humerus• I: Base of styloid process of radius• A: Forearm flexor (thumb up)
BRACHIORADIALIS
EXTENSOR CARPI RADIALIS
• O: Lateral humerus• I: Second and third metacarpal• A: Extends and abducts wrist
Extensor Carpi Ulnaris• O: Lateral epicondyle of humerus• I: 5th metacarpal• A: Extends and adducts the wrist
ULNARIS/RADIALIS
MOVEMENT ANALYSIS PROJECT
• Each group will analyze a movement of their choice• Sports/Functional movement
• Groups of no more than 4, but no less than 2
HOMEWORK
• Create your group• Come to class with the movement your group will
analyze
