|
Deep fascia |
Like stocking Very strong Limits outward expansion of contractions (which help in vein compressing to move blood towards heart) |
|
|
Fascia lata |
Deep fascia of the thigh |
|
|
Fascia lata attaches superior to |
Inguinal ligament Pubic arch Body of pubis Pubic tubercle |
|
|
Scarpa fascia |
Membranous layer of subcutaneous tissue Also attaches to fascia lata |
|
|
Fascia lata attachment |
Iliac crest = laterally and posterior Sacrum = posterior Bones around knee = distally |
|
|
Tight muscle compartments |
1. Anterior (extensor) 2. Medial (adductor) 3. Posterior (flexor) All separated by intramuscular septa |
|
|
Pectineus |
Flat quadrangular muscle (4 angles) On anterior supermedially aspect of thigh |
|
|
Sartorius |
Tailors muscle (long ribbon like) Longest muscle in body Most superficial muscle *acts across both hip and knee!* Mainly synergist muscle (no strong movements) |
|
|
Iliopsoas |
Chief flexor of hip *Formed after merging of two muscle after going deep to inguinal ligament* Uniquic position to Stabilizes (fixate) Postural muscle |
|
|
Quadriceps femoris |
Four headed femoral muscle Great extensor of knee Forms the bulk of the anterior thigh muscles |
|
|
Rectus femoris |
"Kicking muscle" |
|
|
Vastus lateralis |
Largest component of quadriceps |
|
|
Vastus medialis |
Covers distal 2/3 of medial thigh |
|
|
Intramuscular septa |
Separate muscle compartments in the thigh |
|
|
Medial thigh muscles |
Adductor group Innervated by obturator nerve |
|
|
Functions of adductor group |
Adductor hip Stabilize stance with bipedal standing Correct lateral sway of trunk Contribute to flexion of the extended hip Contribute to the extension of the flexed hip |
|
|
Adductor longus |
Most anterior adductor muscle |
|
|
Adductor brevis (deep to what?) |
Deep to the pectineus and adductor longus muscles |
|
|
Adductor magnus |
Has 2 parts Each part has it's own attachment, nerve supply and main action Largest adductor muscle |
|
|
Differnce between action if hamstring and adductor part of adductor magnus |
Hamstring = extends hip Adductor = flex hip |
|
|
Gracillis |
Long strap like muscle ONLY adductor muscle to cross and act at knee AND hip |
|
|
2 muscles that cross both hip and knee |
Sartorius and gracilis |
|
|
Obturator externus |
Deep placed fan shaped muscle |
|
|
Femoral triangle |
Subfascial space Inferior to the inguinal ligament |
|
|
Femoral triangle sides |
Suepriorly: inguinal ligament Medially: adductor longus Laterally: sartorius |
|
|
Apex of femoral triangle |
Where medial border of sartorius crosses the lateral border of the adductor longus |
|
|
Floor and root of femoral triangle |
Floor: pectineus & iliopsoas Roof: |
|
|
Femoral triangle contains |
Femoral artery & vein Femoral nerve |
|
|
Femoral nerve |
Largest branch of lumbar plexus Innervates anterior thigh muscles Deep to inguinal ligament |
|
|
Femoral nerve in femoral triangle |
Divide into terminal thigh muscle branches |
|
|
Cutaneous |
"Skin" |
|
|
Obturator nerve |
Descend along the medial border of psoas major Enter medial compartment of thigh through obturator foramen |
|
|
Intergluteal cleft |
Crack between butt cheeks |
|
|
Gluteal muscles |
1. Gluteus, maximus, medius, minimus 2. Tensor fasciae latae |
|
|
Deep gluteal muscles |
1. Piriformis 2. Obturator internus 3. Superior gemelli 4. Inferior gemelli 5. Quadratus femoris |
