Test 4- Triangles, Spaces, Etc. Flashcards
Adductor hiatus transmits …
Femoral artery and vein from the anterior compartment of the thigh to the popliteal fossa posterior to knee.
Adductor hiatus
Is the opening between the distal aponeurotic attachment of the adductor part of the adductor Magnus and the tendon of the hamstring part
Femoral triangle borders
Superiorly by the inguinal ligament
Medially by the adductor longus
Laterally by the sartorius
Femoral triangle apex
Where the medial border of the sartorius crosses the lateral border of the adductor longus
Femoral triangle floor
Iliopsoas laterally and pectineus medially
Contents of the femoral triangle
Navel…from lateral to medial
Adductor canal
Extends from the apex of the femoral triangle, to the adductor hiatus in the tendon of the adductor Magnus
Adductor canal provides
An intermuscular passage for the femoral artery and vein, saphenous nerve, and the nerve to vastus medialis, delivering the femoral vessels to the popliteal fossa where they become popliteal vessels.
Femoral sheath does not enclose the …
femoral nerve
Compartments for the femoral sheath
Lateral compartment- femoral artery
Intermediate compartment - femoral vein
Medial compartment- which constitutes the femoral canal
Femoral canal contents
Empty space for femoral artery to expand
Loose connective tissue an lymphatics
Popliteal fossa borders
Biceps femoris superolaterally
Semimembranosus superomedially
Lateral and medial heads of gastrocnemius, inferolaterally and infernomedially respectively
Popliteal fossa floor
Popliteal surface of femur
Posterior capsule of the knee joint
Popliteus fascia covering the popliteus muscle
Deepest structure in the popliteal fossa
Popliteal artery…passes close to the joint capsule of knee
Most superficial structure in the popliteal fossa
Tibial branch of sciatic nerve…originates at superior angle of popliteal fossa
