the popliteal fossa
Superficial inguinal nodes recieve lymph from which nodes
External iliac nodes
deep inguinal nodes
Which fascia wraps around all of the thigh
fascia lata
What is the roof of the femoral triangle formed by
fascia lata, cripiform fascia, subcutaneous tissue, skin
What occurs in the saphenous hiatus
great saphenous vein drains to femoral vein
Which fascia sits over saphenous hiatus
Cribiform fascia
Boundaries of femoral triangle
Superior: Inguinal ligament (formed by external oblique aponerouses)
Lateral: Medial border of sartorius
Medial: Medial border of adductor longus
What creates the floor of the femoral triangle
Lateral:
Iliacus
Psoas
Pectineus
Adductor longus
Most medial
Contents of femoral triangle
Femoral nerve: most lateral to psoas muscle
Femoral Artery: continuation of external iliac artery under inguinal ligament
- Include branch (profunda femoris a)
Femoral vein: More Medial, Great saphenous vein pierces in this area to drain into femoral vein.
Lymphatics: Lymphatic ducts (wont see on donors)
(NAVL) (lateral to medial)
Which group of muscles goes anteriorly over the hip joint
the hip flexor muscles
Which muscles are knee extensors
The quadriceps
- Rectus femoris, vastus medialis, vastus lateralis, vastus intermedius
What is the longest muscle in the body
the sartorius muscle
Sartorius OIAI
O: Anterior superior iliac spine
I: Superior part of medial surface of tibia
A: Flex(anterior to joint), abduct(goes diagonally), laterally rotate hip(runs diagonally), flex knee
Inn: Femoral n (L2, 3)
Illiacus OIAI
O: Superior iliac fossa, ala of sacrum, anterior sacro-iliac ligaments
I: lesser trochanter of femur
A: femoral nerve
Inn: flexion of thigh
Psoas major muscle
O: Lumbar vertebrae, T12-L5, Intervertebral discs
I: Lesser trochanter of femur
A: Flexion of thigh
Inn: Anterior rami of L1-L3
Pectineus muscle OIAI
O: Superior pubic ramus
I: pectineal line of femur
A: Adduct and flex thigh, assist w medial rotation
Inn: Femoral Nerve (L2-L3)
Quadriceps muscles AOIO
O:
Rectus femoris: AIIS, Ilium above acetabulum
Vastus lateralis: Greater trochanter, Lateral linea aspera
Vastus medialis: Intertrochanteric line and media aspera
Vastus intermedius: Anterior and lateral shaft of femur
I: Quadriceps tendon then tibial tuberosity via patellar ligament
A: Extend knee (rectus femoris also flexes hip)
Inn: Femoral nerve (L2-L4).
The femoral nerve passes deep to which ligament, medial to what structure, and what muscle does it run on?
Passes deep to inguinal ligament, medial to ASIS, and on tendon of iliopsoas m
Where do muscular branches of femoral nerve run
anterior thigh
Where do articular branches of femoral nerve run
hip and knee
Where do cutaneous branches of femoral nerve run
anteromedial thigh
What is the terminal cutaneous brnach of the femoral nerve
saphenous nerve (anteromedial knee, leg, and foot).
Gracilis OIAI
O:Body and inferior pubic ramus
I:Superior part of medial surface of tibia
A: Adduct thigh, flex leg
Inn:Obturator n (L2-L3)
Adductor longus AIOI
O: Body of pubis inferior to pubic crest
I:Middle 1/3 of linea aspera
A: Adduct and medially rotate thigh
Inn: Obturator (L2-L4)
Adductor Brevis muscle IOAI
O: Body and inferior pubic ramus
I: Pectineal line and linea aspera
A: Adduct and medially rotate thigh
Inn: Obturator (L2-L4)
Adductor Magnus AIOI
O:
Adductor part (anterior): Ischiopubic ramus
Hamstring part: ischial tuberosity
I:
Adductor: gluteal tuberosity, linea aspera, medial supracondylear line
Hamstring part: adductor tubricle of femur
A:
Adducts
Adductor part: flexes
Hamstring part: Extends thigh
Inn:
Add: Obturator (L2-L4)
Ham: Sciatic n
AIOI Obturator externus
O: Margins of obturator foramen and obturator membrane
I: trochanteric fossa (posteriorly which is why it can laterally rotate)
A:laterally rotates thigh
Inn: Obturator n
External iliac turns into femoral artery where
Changes as you go under the inguinal ligament
External liliac branches into what
Femoral artery and profunda femoris
What is the opening of the adductor magnus called
the adductor hiatus
What does the femoral artery go through distially and what does it change into inferiorly
Femoral turns into popleateal artery when it goes through the adductor hiatus
What makes up the cruciate anastomosis
the medial circumflex femoral and lateral circumflex femoral arteries
What do the medial circumflex femoral and lateral circumflex femoral arteries make when they anastamose
The cruciate anastamoses
Where does the obturator nerve run
along lateral wall of pelvis to obturator canal
