Small saphenous vein
Great saphenous vein
• accessory saphenous, superficial external pudendal, superficial epigastric and superficial circumflex iliac veins all join the saphenous vein at proximal end

lateral end of dorsal venous arch (drains to popliteal vein in the popliteal fossa

the medial end of the dorsal venous arch, passes anterior to medial malleolus, posterior to medial epicondyle of femur and passes anteromedial on thigh

the small saphenous vein (on calf of leg), innervates skin of lateral aspect of ankle and foot

(dorsal rami, L1-L3), innervates upper buttock

dorsal rami, S1-S3), innervates middle buttock

(branch of posterior cutaneous n.), innervates lower buttock

- deep to fascia, innervates thigh/popliteal fossa

innervates skin of lateral thigh

- innervates skin of anterior thigh (located lateral to great saphenous vein)

- innervate skin of medial thigh

- branch of femoral n., accompanies great saphenous vein into leg (pierces fascia), innervates the skin on anterior/medial surface of ankle/foot

found on distal 1/3rd of leg on lateral side, gives off dorsal digital nerves that innervates space between 1st and 2nd toe

fascia lata
crural fascia
pedal fascia

lateral portion of fascia lata (runs from iliac tubercle to lateral condyle of tibia, IT band is another name for the tract, gluteus maximus inserts on the IT band

only nerve supply to gluteus maximus

supplies gluteal muscles as it exits above the piriformis muscle within the greaer sciatic notch

runs with superior gluteal a., innervates gluteus medius and minimus as well as tensor fasciae latae

o: Anterior surface of sacrum between anterior sacral foramina
i: Medial side of superior border of greater trochanter of femur
n: Branches from L5, S1, S2
f: Laterally rotates the extended femur at hip joint; abducts flexed femur at hip joint

o: Anterolateral wall of true pelvis; deep surface of obturator membrane and surrounding bone

o: External surface of ilium between anterior and posterior gluteal lines
i: Elongate facet on the lateral surface of the greater trochanter
n: Superior gluteal nerve (L4, L5, S1)
f: Abducts femur at hip joint; holds pelvis secure over stance leg and prevents pelvic drop on the opposite swing side during walking; medially rotates thigh

o: Fascia covering gluteus medius, external surface of ilium behind posterior gluteal line, fascia of erector spinae, dorsal surface of lower sacrum, lateral margin of coccyx, external surface of sacrotuberous ligament
i: Posterior aspect of iliotibial tract of fascia lata and gluteal tuberosity of proximal femur
n: Inferior gluteal nerve (L5, S1, S2)
f: Powerful extensor of flexed femur at hip joint; lateral stabilizer of hip joint and knee joint; laterally rotates and abducts thigh

o: Lateral aspect of crest of ilium between anterior superior iliac spine and tubercle of the crest
i: Iliotibial tract of fascia lata
n: Superior gluteal nerve (L4, L5, S1)
