  3. Femoral Artery, Vein, and Nerve

  4. Femoral Artery • The Femoral Artery takes blood away from the heart to the medial thigh.

  5. Femoral Vein • The Femoral Vein takes blood to the heart away from the medial thigh.

  6. Femoral Nerve • The Femoral Nerve sends and receives impulses to the medial thigh.

  7. Sartorius – Free and Transect • O: Ilium I: Tibia P: Flex Leg Freed Transected

  8. Gracilis – Free and Transect • O: Pubis and Ischium I: Tibia P: Adduct the Thigh Freed Transected

  9. Saphenous Artery, Vein, and Nerve • Artery –Takes blood from heart to lower leg and foot • Vein –Takes blood to heart from lower leg and foot • Nerve –Sends and receives impulses to lower leg and foot * A Branch of the Femoral = Saphenous A,V,N = Sartorius

  10. Obturator Nerve • Sends and Receives Impulses to medial thigh (Gracilis) *The left leg is tilted (Picture taken from side)

  11. Tensor Fascia Lata • O: Iliac Crest I: Fascia Lata P: Flex Thigh

  12. Quadriceps Femoris • Composed of 4 muscles : • Rectus Femoris • Vastus Lateralis • Vastus Intermedius • Vastus Medialis

  13. Rectus Femoris – Free and Transect • O: Innominate Bone I: Tibia P: Extends Leg Transected Freed

  14. Vastus Lateralis – Expose • O: Femur I: Tibia P: Extends Leg *Cat horizontal- picture taken from side * Rectus Femoris Transected

  15. Vastus Intermedius – Expose • O: Femur I: Tibia P: Extends Leg *Cat horizontal- picture taken from side * Rectus Femoris Transected

  16. Vastus Medialis – Expose • O: Femur I: Tibia P: Extends Leg *Cat vertical as in example ^ *Cat horizontal- picture taken from side* Rectus Femoris Transected

  17. Lateral Circumflex Femoral A,V = Rect. Fem. = LCF A,V • Artery –Takes blood from heart to quadriceps femoris muscle mass • Vein –Takes blood to heart from quadriceps femoris muscle mass * A Branch of the Femoral

  18. Adductor Longus and Femoris -Expose • Longus - O: Pubis I: Femur P: Adduct the Thigh • Femoris -O: Pubis and Ischium I: Linea Aspera P: Adduct the Thigh

  19. Deep Femoral Artery and Vein • Artery –Takes blood from heart to adductors • Vein –Takes blood to heart from adductors * A Branch of the Femoral This blood vessel, deep to the adductors, can be found between the Adductor Longus and the Vastus Medialis.

  20. Semimembranosus, Semitendinosus -Expose • Semimem. - O: Ischium I: Medial aspect of Tibia P: Flex the Leg • Semitend. -O: Ischium I: Medial aspect of Tibia P: Flex the Leg

  21. Biceps Femoris –Free and Transect • O: Ischium I: Tibia and Fibula P: Flex the Leg Freed Transected

  22. Sciatic Nerve • Sends and receives impulses to the posterior muscles of the thigh (Biceps Femoris)

  23. Popliteal Artery and Vein • Artery –Takes blood from heart to the back of the knee • Vein –Takes blood to heart from back of the knee *Branches off of the Deep Femoral

  24. Gluteus Medius, Gluteus Maximus -Expose • Medius - O: Ilium I: Femur P: Abduct Thigh • Maximus. - O: Sacral Vertebrae I: Femur P: Abduct Thigh Gluteus Max

  25. Caudofemoralis • O: Caudal Vertebrae I: Patella P: Abduct Thigh = Gluteus Maximus = Biceps Femoris

  26. Gastrocnemius • O: Lateral and Medial Popliteal Surface of Femur I: Calcaneous P: Extends the Foot

  27. Soleus • O: Posterior Aspect of Tibia I: Calcaneous P: Extends the Foot

  28. Tibial Nerve • Sends and receives impulses to the posterior lower leg. (Tibia)

  29. Peroneus Brevis, Longus, Tertius

  30. Peroneus Brevis • O: Fibula I: Metatarsals P: Extends Foot

  31. Peroneus Tertius • O: Fibula I: Phalanges P: Extends Foot

  32. Peroneus Longus • O: Fibula I: Metatarsals P: Pronates Foot

  33. Peroneal Nerve The Peroneal Nerve sends and receives impulses to the anterior and lateral lower leg muscles (shin area). It is a branch of the Sciatic Nerve

  34. Tibialis Anterior • O: Tibia I: Phalanges P: Flex Foot

  35. Extensor Digitorum Longus • O: Femur I: Phalanges P: Extends the Toes

  36. Capsule Cavity • In the knee; houses the quadriceps tendon, synovial membrane, crossed ligaments, and semilunar cartilage.

  37. Quiz on the Lower Leg This 20 question quiz is on the reading and dissection. Write your answers on piece of paper.

  38. Question 1 Name this muscle and give the OIP for it.

  39. Question 2 Multiple/Multiple What muscle(s) were transected? • Biceps Femoris • Tensor Fascia Lata • Rectus Femoris • All of the Above • None of the Above

  40. Question 3 Which blood vessel carries blood to and from the back of the knee? • Saphenous Artery and Vein • Backknee Artery and Vein • Popliteal Artery and Vein • Femoral Artery and Vein

  41. Question 4 This is composed of four (4) muscles. What is this called and name the four (4) muscles it’s made up of.

  42. Question 5 What ligament is located between the pubic tubercle and the anterior superior iliac spine?

  43. Question 6 What holds the Tensor Fascia Lata to its insertion?

  44. Question 7 What muscle is this? Give the OIP

  45. Question 8 True and False Is this statement true or false? If false, fix it. The Lateral Circumflex Femoral Artery and Vein is located in the Biceps Femoris.

  46. Question 9 • How many hamstring muscles are there? • What are the names?

  47. Question 10 Are the tendons of the Semimembranosus and Semitendinosus more rounded or aponeurotic in cat?

  48. Question 11 The insertion of the Caudofemoralis is located between what two things?

  49. Question 12 Where is the Sciatic Nerve located?

  50. Question 13 What muscle in the lower leg (shin area) has two heads of origin?
