GAP Topic 17 & 18 Review Questions 1. Define the borders of the quadrangular space: a. Superior: teres minor b. Inferior: teres major c. Medial: long head of triceps d. Lateral: shaft of humerus e. Roof: deltoid 2. In what location would you palpate for the brachial pulse? 2-3 inches proximal to the medial epicondyle of the humerus between biceps and triceps 3. Define the boundaries of the cubital fossa: a. Superior: imaginary line between the medial epicondyle and lateral epicondyle of the humerus b. Medial: pronator teres c. Lateral: brachioradialis 4. The forearm muscles are divided into two groups, what are they? a. Flexor (anterior) b. Extensor (posterior) 5. What group is concerned with golfers' elbow? At what Epicondyle? The flexor group through the common tendon at the medial epicondyle 6. The Flexor compartment is subdivided into 3 compartments, list the compartments and the muscles found within them: a. Superficial – pronator teres, flexor carpi radialis, palmaris longus, flexor carpi ulnaris b. Intermediate – flexor digitorum superficialis c. Deep – flexor digitorum profundus, flexor pollicis longus, pronator quadratus 7. The tendons of the superficial flexor compartment are held down by a thickening of the fascia called: flexor retinaculum (aka transverse carpal ligament) 8. Define the Origin, Insertion, Action for Pronator Teres: a. Origin: medial epicondyle, coronoid process b. Insertions: middle lateral surface of radius c. Action: pronates forearm 9. Define the Origin, Insertion, Action for Flexor Carpi Radialis: a. Origin: medial epicondyle b. Insertions: base of the 2nd metacarpal c. Action: wrist flexion and radial deviation 10. Define the Origin, Insertion, Action for Palmaris Longus: a. Origin: medial epicondyle b. Insertions: palmar aponeurosis and distal ½ of flexor retinaculum c. Action: wrist flexion and tightens palmar fascia 11. Define the Origin, Insertion, Action for Flexor Carpi Ulnaris: a. Origin: medial epicondyle, olecranon and posterior ulna b. Insertions: pisiform, hook of hamate, base of the 5th metacarpal c. Action: wrist flexion and ulnar deviation 12. Define the Origin, Insertion, Action for Flexor Digitorum Superficialis: a. Origin: medial epicondyle, ulnar collateral ligament, coronoid process b. Insertions: middle phalanx of medial 4 digits c. Action: flexion of medial 4 digits at PIP joints, flexion of MCP joints with stronger contraction and assists with wrist flexion 13. Define the Origin, Insertion, Action for Flexor Digitorum Profundus: a. Origin: proximal ¾ of anterior and medial surface of ulna and interosseous membrane b. Insertions: base of distal phalanx of digits 2-5 c. Action: flexes distal phalanges 2-5 at DIP joints and assists with wrist flexion 14. Define the Origin, Insertion, Action for Flexor Pollicis Longus: a. Origin: anterior surface of radius and interosseous membrane b. Insertions: base of distal phalanx of pollicis c. Action: flexes pollex at IP and MCP 15. Define the Origin, Insertion, Action for Pronator Quadratus: a. Origin: distal ¼ of anterior ulna b. Insertions: distal ¼ of anterior radius c. Action: pronation of forearm
