  3. What are the boundries of the Femoral Triangle?
    • Superior: inguinal ligament
    • Lateral: Sartorius
    • Medial: adductor longus (lateral border of the adductor longus)
    • Roof: Fascia lata
    • Floor: Iliopsoas (Medial), Pectineus (lateral)
  4. What are the contents of the femoral triangle?
    • Lateral Femoral Nerve
    • Femoral N.
    • Femioral A./V. (in a bundled sheath)
    • Profunda femoris (Latreal and medial femoral circumflex a.) - main provider of blood to the thigh after it passes through the femoral canal it becomes the popliteal a.
    • Medial and Lateral femoral circumflex a. are the main suppliers to the head and neck of the femur.
  5. Which are the main veins of the lower extremity?
    • Dorsal Venous Arch, Greater Saphenous, Perforating Veins

  6. What is the adductor canal? When does it begin and end? What are the other names for it? Which muscles form it? What passes through it?
    • The fascial sheath deep to the sartorius and superficial to the adductor longus.
    • Begins when the sartorius passes over it, and ends at the adductor hiatus in the tendon of the adductor magnus muscle
    • Hunter's canal, subsartorial canal
    • Sartorius and adductor longus
    • Fermoral a., and v. and the saphenous n. which is a cutaneous branch of the femoral n.
  7. What are the three compartments of the thigh and their contents? What creates those compartments?
    • Anterior: Leg extensors, femoral n.
    • Medial: Thigh adductors, obturator n.
    • Posterior: Leg flexors and thigh extensors, sciatic n.
    • Intermuscular septa - which is an extension of the fascia lata
  8. Which nerves are involved in cutaneous innervation of the anterior thigh?
    • Subcostal n T12: lateral aspect of the thigh, anterior to greater trochanter
    • Iliohypogastric: lateral (skin over the superolateral buttocks) and anterior (skin superior to the pubis) branches
    • Ilioinguinal: Travels through the superficial inguinal ring to innervate the inferior pelvis. (also travels the proximal medial aspect of the thigh)
    • Genitofemoral; branches that extend into the pelvis, branches that innervate the skin of the thigh, inferior to the inguinal ligament on the medial aspect
    • Lateral femoral cutaneous: lateral and anterior parts of the skin of thigh. Pass under the lateral aspect of the inguinal ligament. extends laterallt and distally from the greater trochan, to area just proximal the knee.
    • Femoral n.: Skin of anterior and medial thigh
    • Anterior femoral cutaneous: arises from femoral n. in femoral triangle. Runs along part of the Sartorius muscle and innervates the skin of the anterior and medial aspect of the thigh.

  23. Which of the menisci of the tibia is torn more commonly?
    They are actually torn equally even though the medial is considered to be torn more frequently. Lateral is just as common because it is more mobile.
