Where, and via what structure does the Subscapularis muscle attach? Ans- Subscapularis muscle via its tendon gets attached onto the lesser tuberosity of Humerus. 5. What action does the Supraspinatous muscle perform? Ans-Supraspinatous helps to abduct the arm and stabilises the shoulder joint. 6. Where is the transverse humeral ligament? Ans-Transverse humeral ligament is present in between greater and lesser tuberosity of the Humerus. 7. What happens to the long head of biceps tendon when the transverse humeral ligament is ruptured? Ans- Transverse humeral ligament stretches in between greater and lesser tuberosity to position long head of the bicep brachii in the bicipital groove. Rupture of transverse humeral ligament results in dislocation of the long head of bicep tendon. 8. Describe the course of the long head of biceps tendon Ans- Long head of biceps tendon arises from supraglenoid tubercle of scapula and further lies in the capsule of shoulder joint. It emerges from there in a hiatus between the tendons named as Subscapularis and Supraspinatous tendons. It passes through the bicipital groove, where it joins with the short head of bicep tendon and distally attaches onto the radial tuberosity. 9. What is the function of bursae? Ans-Bursae act to allow easy movement of one part upon another. Some even lie between skin and bony prominences, such as the kneecap or elbow and allow the skin to move with less friction over the underlying parts. 10. What is a sesamoid bone? Ans- Patella, situated anterior to the knee joint is a sesamoid bone as it is embedded within the tendon of the quadriceps femoris muscle. 11. Name two bursae which communicate with the knee joint capsule Ans-Popliteal burse and suprapatellar bursa-these two bursae communicate with the knee joint capsule. 12. Where is the most common location for a Baker's Cyst? Ans- The commonest location for Baker’s Cyst is the synovial cavity of the knee joint. 13. What is attached to the medial aspect of the medial collateral ligament? Ans- Medial meniscus is attached to the medial aspect of medial collateral ligament of the knee. 14. What two tendons are located posterior to the fibular? Ans- Flexor hallucis longus and Tibialis Posterior is located posterior to Fibular shaft. 15. Describe one clinical test to evaluate the integrity of the Achilles tendon Ans- Patient is asked to be prone with affected side knee is flexed to 90 degrees. Calf muscles are squeezed to check for passive planter flexion which is the indication of intact Achilles tendon. 16. What are the attachments of the Anterior Cruciate Ligament? Ans- Anterior Cruciate ligament is attached to anterior intercondyler eminence of the tibia and medial side of the lateral condyle of the femur. 17. What are the attachments of the Posterior Cruciate Ligament? Ans- Posterior Cruciate ligament is attached to the posterior intercondyler eminence of the tibia and to the lateral side of the medial condyle of the femur. 18. Coronal oblique images of the shoulder are aligned parallel to what structure? Ans- Coronal oblique images of the shoulder are aligned parallel to Supraspinatous muscle. 19. What ligaments are often injured in an acute sprain of the lateral ankle? Ans- Acute sprain of ankle often injures anterior talofibular ligament and calaneofibular ligament. 20.
