3. Adductor Brevis 3

4. Origin of Adductor Brevis 4 Anterior surface of body of the pubis Outer surface of inferior ramus of the pubis between the gracilis and obturator externus Outer surface of ramus of the ischium between gracilis and adductor magnus

5. Insertion of Adductor Brevis 5 Line extending from the lesser trochanter to the upper part of the linea aspera, behind the upper part of the adductor longus

6. Innervation of Adductor Brevis 6 Anterior and posterior division of obturator nerve

7. Actions of Adductor Brevis 7 Adductor longus, adductor brevis help in adduction and flexion of thigh

8. Adductor Longus 8 The adductor longus is a large, fan-shaped muscle located in the medial aspect of the thigh It belongs to the adductors of the thigh, together with adductor brevis It lies in the plane of the pectineus

9. Origin of Adductor Longus 9 It arises by a narrow, flat tendon from the front of the body of the pubis in the angle between the pubic crest and the pubic symphysis.

10. Insertion of Adductor Longus 10 The linea aspera in middle one-third of the shaft of the femur between the vastus medialis and the adductor magnus and brevis

11. Innervation of Adductor Longus 11 Anterior division of obturator nerve

12. Actions of Adductor Longus 12 Powerful adductor of thigh at hip joint, also act as posture controllers

13. Adductor Magnus 13 The adductor magnus muscle is a large triangular muscle of the lower limb, with its apex situated on the hip bone, and its base on the linea aspera of the femur Because of its dual nerve supply, its called a hybrid muscle

14. Origin of Adductor Magnus 14 Inferolateral part of the ischial tuberosity Ramus of the ischium Lower part of inferior ramus of the pubis

15. Insertion of Adductor Magnus 15 Medial margin of gluteal tuberosity Linea aspera Medial supracondylar line Adductor tubercle

16. Innervation of Adductor Magnus 16 Double nerve supply: Anterior part by posterior division of obturator nerve Hamstring part by tibial part of sciatic nerve

17. Actions of Adductor Magnus 17 Adductor part causes adduction of thigh and hamstring part helps in extension of hip and flexion of knee

18. Gracilis 18 Gracilis muscle is a long and slender muscle located in the medial (adductor) compartment of the thigh Gracilis is the most superficial hip adductor, overlying the remaining four t is also the weakest member but the only hip adductor that crosses and acts on two joints; the hip and knee.

19. Origin and insertion of Gracilis 19 Medial margin of the lower half of the body of pubis Inferior ramus of the pubis Adjoining part of the ramus of the ischium Upper part of the medial surface of the tibia behind the sartorius and in front of the semitendinosus Origin Insertion

20. Innervation of Gracilis 20 Anterior division of obturator nerve

21. Action of Gracilis 21 Flexor and medial rotator of thigh Weak adductor of thigh Used for transplantation of any damaged muscle

22. Clinical Anatomy 22 The gracilis muscle is most superficial muscle of the adductor compartment. This muscle is often used for transplantation of any damaged muscle. Intracapsular fracture of neck of femur causes damage to the retinacular branches (which supply head of femur), leading to avascular necrosis of head of femur
