Important Topics - Anterior & Medial Thigh Flashcards
What are the Pes Anserinus m and their innervations (What is the mnemonic)
sartorious m — femoral n gracilis m — obturator n semitendinosus m — tibial division of the sciatic n. SGT-FOT
What is the adductor canal
aka hunter canal Conical tunnel formed by the ANTEROMEDIAL INTERMUSCULAR SEPTUM from the adductor Magnus muscle. It’s termination is the Adductor Hiatus and start is the apex of the femoral triangle
Contents of the adductor canal and what exits
femoral a femoral v saphenous n nerve to vastus medialis m Politeal A and V
Primary cutaneous innervations of the thigh, where they derive and what the service
1) Lateral femoral cutaneous n — L2-L3 — anterior and lateral thigh 2) Obturator N. —- L2-L4 —– various muscles and sensory info for medial thigh 3) Femoral Branch of the genitofemoral n. — L1-L2 —- sensory (labia majora and scrotum), medial thigh
What do the superficial inguinal lymph nodes drain and what are some clinical examples to look out for
All parts of the lower extremities EXCEPT the dorsolateral foot and the posterior calf — those are drained by the popliteal lymph nodes STIs Medial Foot/Leg cellulitis Skin cancer
What borders the adductor canal
1) adductor longus and magnus ms. (posterior) 2) sartorious m (anteromedial) 3) vastus medialis (lateral)
What are the posterior retinicular arteries?
branches of the medial and lateral circumflex femoral arteries that feed the head and neck of the femur —- essential for anastomosis and preventing avascular necrosis though could still happen in femur fracture
Describe the Great Saphenous Vein
-Longest vein in the body -travels through the medial side of leg and thigh -Terminates in the saphenous hiatus near the acetabulofemoral joint
What are the two groups of the superficial inguinal lymph nodes and what do they drain
1) Superior (horizontal group) - inferior abdominal wall, penis, scrotum, vulva, lower vagina, lower anal canal 2) Inferior (vertical group) - superficial tissue of LE
Fascia lata
A dense layer of CT that surrounds the entire thigh and is deep to subcutaneous fascia -INTERMUSCULAR SEPTA is an extension of fascia lata
Iiotibial Tract
aka IT Band -Fibers of fascia lata with vertical orientation -APONEUROSIS of Glut Max. and Tensor Fascia Lata -Inserts into Gerdy’s Tuberacle (lateral aspect of proximal tibia)
What are four important Bursae and where are they located
1) Iliopectineal bursa – Iliopsoas m. 2) Bursa of semimembranosus and anserine bursa 3) Bursa deep to iliotibial tract – lateral aspect of fibula 4) Suprapatellar pouch – posterior to the Quad tendon and patellar L.
