Q1. To which bone do the medial and lateral intermuscular septa of the arm attach?
- Ulna only
- Radius only
- Humerus
- Scaphoid
Q2. Which intermuscular septum is associated with the passage of the ulnar nerve from the anterior to the posterior aspect of the distal arm?
- Interosseous membrane
- Flexor retinaculum
- Lateral intermuscular septum
- Medial intermuscular septum
Q3. Which nerve pierces the lateral intermuscular septum as it passes from the posterior toward the anterior aspect of the distal arm?
- Radial nerve
- Ulnar nerve
- Axillary nerve
- Median nerve
Q4. The brachial fascia is continuous inferiorly with which fascia?
- Thoracolumbar fascia
- Plantar fascia
- Crural fascia
- Antebrachial fascia
Q5. Which structure reinforces the deep fascia over the cubital fossa medially?
- Coracohumeral ligament
- Bicipital aponeurosis
- Extensor retinaculum
- Annular ligament
Q6. The antebrachial fascia provides attachment for which type of structures in the forearm?
- Only rotator cuff muscles
- Only muscles of the posterior shoulder
- Only the intrinsic muscles of the hand
- Some superficial forearm muscles
Q7. What is the functional significance of fascial septa extending from deep fascia toward bone?
- They form the articular surfaces of bones
- They help separate muscle groups into compartments
- They replace peripheral nerves
- They create synovial cavities around all muscles
Q8. What is a major mechanical function of the extensor retinaculum?
- Preventing elbow flexion
- Producing wrist extension
- Forming the superficial palmar arch
- Preventing bowstringing of extensor tendons
Q9. Which structure forms the roof of the carpal tunnel?
- Interosseous membrane
- Extensor retinaculum
- Antebrachial fascia alone
- Flexor retinaculum
Q10. Why are fascial compartments anatomically useful for describing the upper limb?
- They eliminate communication between all adjacent tissues
- They organize muscles and their neurovascular relationships into functional groups
- They are identical to synovial joint cavities
- They contain only arteries and no muscles
