1.5.2 Anterior Thigh, Femoral Triangle, and Medial Thigh Flashcards
What are the two important veins of the leg and what is their surface anatomy?
What are the two important fascia of the lower leg?
What is the origin of the iliopsoas muscle?
Psoas - Vertebral body and transverse process of T12-L5
Iliacus - Iliac crest, iliac fossa, ala of sacrum, and anterior sacroiliac ligament
What is the insertion of the iliopsoas?
Inserts into lesser trochanter of femur
What is the action of the iliopsoas?
Flexes the thigh/trunk at the hip and advances the lower limb during walking gait
What are the nerves of the iliopsoas?
Lumbar nerve and the femoral nerve
What are the characteristics of the pectineus muscle?
Where does the sartorius originate and insert
Origin - anterior superior iliac spine
Insert - Upper medial tibia
What is the movement and innervation of the sartorius muscle?
Weakly flexes, abducts and laterally rotates the thigh, flexes the leg
Femoral nerve
What is the superior attachment of the rectus femoris?
Anterior inferior iliac spine
What are the 4 muscles of the quadricep femoris?
Rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius
What is the superior attachment of the vastus lateralis?
Greater trochanter, lateral lip of linea aspera of femur
What is the superior attachment of the vastus medialis?
Inter-trochanteric line, medial lip of linea aspera
What is the superior attachment of the vastus intermedius?
Shaft of femur
What is the inferior attachment of the quadricep femoris?
Forms the common quadricep tendon to patella and the via the patellar ligament to tibial tuberosity
What is the action and innervation of the quadricep femoris?
Powerful extensor of the leg at the knee
Femoral nerve innervation
Describe the function of the quadricep femoris?
What are the characteristics of the femoral nerve?
What are the covered parts?
What are the different branches of the femoral artery?
What is the blood supply to the head of the femur and hip joint?
What are the important bursae at the insertion of the quadricep femoris?
What is the common site of bursitis of the knee?
Quadricep tendon bursitis - at suprapatellar pouch
What are some common clinical symptoms related to anterior thigh trauma?
What is a posas abscess?
Striking the patellar ligament is commonly used to test the?
Perpipheral proprioception nerve reflex arc (Spinal L2,3, and 4)
What is the importance of the femoral triangle and what is the contents?
Describe the roof or anterior wall of the femoral triangle
The femoral sheath is a pouch containing what? It is a potential passage for what?
Contains the - Femoral artery, vein and femoral canal.
Potential passage of femoral hernia
What are the covered parts?
What are some clinical considerations of the femoral triangle?
Why is the saphenous nerve different than the other branches of the femoral nerve?
Only the saphenous nerve exits the triangle - sensory to skin and medial calf
What are the characteristics of a femoral hernia?
What muscles of the medial thigh attach to the pelvis and femur?
Adductor longus, adductor brevis, adductor magnus, gracilis, and obturator externus
The adductor magnus is innervated by the obturator and?
Has tibial nerve contribution
What is the origin and attachment of the adductor longus?
Body of pubis and attaches to middle 1/3rd of linea aspera
What is the function and innervation of the adductor longus?
What is the attachment and origin of the adductor brevis?
Arises on the body and inferior ramus of the pubis. Attaches to the pectineal line and proximal linea aspera
What is the function and innervation of the adductor brevis?
What is the origin and insertion of the adductor magnus (adductor part)?
Arises on the inferior pubic ramus, ischial ramus
Attaches to femoral gluteal tuberosity, linea aspera, medial supracondylar line
What is the function and innervation of the adductor magnus (adductor part)?
Adducts and flexes the thigh.
Obturator nerve
What is the origin and insertion of the adductor magnus hamstring part?
From ishial tuberosity to adductor tubercle of femur
What is the function and innervation of the adductor magnus - hamstring part?
Extends thigh
Tibial nerve innervation
What is the origin and insertion of the gracilis?
From body and inferior ramus of pubis to superior/medial surface of tibia
What is the function and innervation of the gracilis?
Adducts the thigh, flexes leg and medially rotates
Obturator nerve
What are the characteristics of the obturator externus?
What are the characteristics of the obturator nerve?
The obturator nerve cutaneous innervation is?
Superficial branch innervates distal thigh medially
What artery provides blood to the medial adductor muscle group?
Obturator artery
What are some anastomoses between the internal and external iliac arteries?
What are the clinical symptoms of Per Anserinus Bursitis?
What are the clinical symptoms of a groin pull?
