Find/palpate the following landmarks: o Medial and lateral epicondyles of the femur o Tibial tuberosity o Anterior border of tibia (shin bone) o Base and apex of patella KNEE JOINT The knee joint is the largest synovial joint in the body. It is basically a hinge joint reinforced by very strong ligaments. Movements of the knee are mainly flexion and extension. It consists of the two articulations: 1) between the femur and tibia and 2) between the patella and the femur. Name the specific articular surfaces involved in each of these 2 articulations: o between the femur and tibia o between the patella and the femur Identify the following knee structures: o tibial (medial) and fibular (lateral) collateral ligaments o anterior and posterior cruciate ligaments o patellar ligament o medial and lateral menisci o the 3 bursae around the patella: suprapatellar, infrapatellar, prepatellar 1. What type of injury might damage the tibial (medial) collateral ligament? 2. What type of injury might damage the anterior cruciate ligament? 3. What is the purpose of the bursae? MUSCLES OF THE THIGH The Quadriceps Group Adductors Hamstrings •Sartorius •Gracilis •Biceps Femoris •Rectus Femoris •Pectineus •Semitendinosus •Vastus Lateralis •Adductor Magnus •Semimembranosus •Vastus Medialis •Adductor Longus •Vastus Intermedius •Adductor Brevis 1. Which muscles are collectively known as the Quadriceps Femoris? 2. What is the common insertion of the Quadriceps Femoris muscles? 3. Why is the Sartorius sometimes referred to as the “tailor’s muscle”? 4. What is the common origin of the Hamstrings muscles? 5. What is meant by a ‘bifunctional’ muscle? 6. List the bifunctional muscles of the thigh and their actions. 7. What muscle attaches to the adductor tubercle? 8. a) Which muscles originate from the pubis bone? b) What is the common action of these muscles? c) Where do many of these muscles insert? 9. Palpate and identify the following surface landmarks: o tendon of biceps femoris o tendon of semitendinosus o the outlines of the knee extensors 10. How would you stretch the iliotibial tract (iliotibial band, or ITB)? 11. How would you stretch the rectus femoris muscles? Is this different from stretching the other quadriceps muscles? Why? 12. What are the key hip and thigh muscle groups worked by the following actions: A) Rising from a chair, B) Lunges, C) Straight leg raise in supine. ...
