Q1. Which movement places the biceps brachii in the best mechanical position to act as a powerful supinator?
- Supination with the elbow flexed
- Wrist flexion with the elbow extended
- Pronation with the elbow extended
- Finger extension with the forearm pronated
Q2. Which reflex is commonly used to assess the musculocutaneous nerve and predominantly the C5 and C6 spinal levels?
- Triceps tendon reflex
- Biceps tendon reflex
- Achilles reflex
- Patellar reflex
Q3. A rupture of the proximal long head tendon of biceps brachii can produce which characteristic appearance?
- Wrist drop
- Claw hand
- Winged scapula
- Popeye deformity
Q4. Which function is particularly weakened after complete distal biceps tendon rupture?
- Scapular protraction
- Finger abduction
- Wrist extension
- Forearm supination
Q5. Which test is commonly used to assess the integrity of the distal biceps tendon?
- Phalen test
- Hook test
- Thompson test
- Trendelenburg test
Q6. Which statement best describes the course of the long head tendon within the shoulder?
- It passes through the quadrangular space
- It passes through the cubital tunnel
- It passes intracapsularly before entering the intertubercular sulcus
- It passes posterior to the scapular spine
Q7. Which structure helps stabilize the tendon of the long head of biceps brachii near the proximal intertubercular sulcus?
- Triangular fibrocartilage complex
- Biceps pulley structures
- Annular ligament of the radius
- Ulnar collateral ligament of the elbow
Q8. Which structure lies medial to the brachial artery in the central part of the cubital fossa?
- Radial nerve
- Median nerve
- Biceps tendon
- Cephalic vein
Q9. A lesion of the musculocutaneous nerve proximal to its muscular branches would most directly weaken which combination of movements involving the biceps brachii?
- Wrist extension and finger extension
- Finger abduction and adduction
- Elbow flexion and forearm supination
- Elbow extension and forearm pronation
Q10. Which description best summarizes the biceps brachii?
- A shoulder muscle supplied by the axillary nerve that abducts the arm
- A two headed anterior arm muscle that flexes the elbow and powerfully supinates the forearm
- A posterior arm muscle that extends the elbow and pronates the forearm
- A forearm muscle that primarily extends the wrist
