Medial thigh: adductor compartment

Question 1

pectineus

Answer 1

• origin: pecten of pubis
• insertion: pectineal line of femur just inferior to LT
• action: adducts, flexes, and medially rotates the thigh

Question 2

gracilis

Answer 2

• origin: pubic symphysis and the inferior pubic ramus
• insertion: medial surface of the tibia (via pes anserinus) below condyle
• action: adducts the thigh, flexes and medially rotates leg when knee is flexed

Question 3

adductor longus

Answer 3

• origin: superior pubic ramus
• insertion: linea aspera of the femur
• action: adducts, flexes, and medially rotates the femur
• most anterior

Question 4

adductor brevis

Answer 4

• origin: inferior pubic ramus
• insertion: pectineal line and proximal linea aspera (deep to the pectineus and adductor longus mm.)
• action: adducts, flexes, and medially rotates the femur

Question 5

adductor magnus

Answer 5

• origin: inferior pubic ramus, ramus of ischium, ischial tuberosity
• insertion: gluteal tuberosity, linea aspera, medial supracondylar line, adductor tubercle of femur
• action: adducts, superior portion weakly flexes and medially rotates the femur; lower portion helps extend and laterally rotate thigh
• supracondylar portion: adductor portion
• adducto tubercle region: hamstring portion
