Brachialis
What is Originates from anterior surface of the humerus, particularly the distal half and inserts at Base of styloid process of radius
100
Retracts scapula and rotates it to depress glenoid cavity; fixes scapula to thoracic wall? From C7 - T5 to medial border of scapula from spine to inferior angle
What is Rhomboids
100
Biceps Brachii
What is Flexes and supinates the forearm
100
MOI: Overuse Falling on an outstretched hand Forceful overhead movements (abduction/flexion/medial rotation) PATH: Supraspinatus most often injured S&S: Pain, Inflammation, Weakness
What is Rotator Cuff Strains
100
Biceps Brachii
What is Flexes shoulder, Flexes elbow, Supinates forearm
200
Extensor Indicis
What is Originates at?Middle third of posterior ulna and Inserts at Base of distal phalanx of thumb
200
Function: Elevates, retracts, and rotates scapula Superior fibers: elevate Middle fibers: retract Inferior fibers: depress
What is Trapezius
200
Brachioradialis
What is Contributes to elbow flexion
200
MOI: Arm is forcefully abducted and laterally rotated May occur by a blow to top of shoulder PATH: Head of humerus is forced out of the glenoid fossa S&S: Arm held out from side in a position of slight abduction and lateral rotation Loss of normal rounded contour of deltoid muscle
What is Dislocation of the Shoulder
200
Supinator
What is Supination of the forearm
300
Levator Scapulae
What is Originate From C1 - C4 Inserts at superior part of medial border of scapula
300
Weakly flexes wrist ORIGIN?Common flexor origin of medial epicondyle of humerus INSERTION?Flexor retinaculum and palmar aponeurosis
What is Palmaris Longus
300
Teres Minor
What is Laterally rotates shoulder Adducts shoulder Extends shoulder Horizontally abducts shoulder Stabilizes head of humerus in glenoid cavity
300
MOI: Repetitive stress injury PATH: Microtraumas or tears in muscle &soft tissue at proximal attachments S&S: Pain on activity Treatment: Rest, Ice, anti-inflammatory drugs, & possibly cortisone injection
What is Lateral epicondylitis – “tennis elbow” Medial epicondylitis – “Little league elbow”
300
Triceps Brachii
What is Powerful extensor of elbow
400
Flexor Carpi Radialis
What is Originates from medial epicondyle of humerus Inserts at?Bases of 2nd and 3rd metacarpals via groove in trapezium
400
Pronation of the forearm Origin: medial, anterior surface of the ulna Insertion: lateral, anterior surface of the radius
What is Pronator Quadratus
400
Serratus Anterior
What is....... Protract scapula ? .....With trapezius upward rotation of scapula? ....Active in reaching and pushing
400
Inflammation of the tendon that runs down the forearm, through the wrist, to the thumb.
What is De Quervain’s tendonitis
400
Extensor Pollicis Brevis
What is Extends thumb
500
Triceps Brachii
What is originates from Long head: infraglenoid tubercle of scapula Lateral head: above the radial sulcus Medial head: below the radial sulcus Inserts at the Olecranon process of ulna
500
Function: Small triangular muscle, placed between the clavicle and the first rib. Protect and stabilize SC joint? and Depresses the scapula
What is Subclavius
500
Anconeus
What is Working with the triceps, extends the forearm
500
A high-energy injury in which the ligament at the base of the thumb is torn. This occurs when the patient falls forward and the thumb is bent backward.
What is Skier’s thumb
500
Flexor Carpi Ulnaris
What is Flexes wrist and Ulnar deviation
