What medial compartment muscle is not innervated by the obturator n.?
Pectineus m.
What are the muscles of the medial thigh?
Pectineus, adductor longus, adductor brevis, 1/2 adductpr agnus, gracilis
What is the origin and insertion of the pectineus m.?
Origin: superior ramus of pubis
Insertion: Pectineal line of femur
What arteries supply blood to the quadriceps femoris mm.?
Deep femoral artery and lateral circumflex femoral artery
What arteries supply blood to the pectineus?
- medial circumflex artery
- obturator artery
Action of the pectineus m.?
Adduction of the thigh, assists with flexion and medial rotation of the thigh
Origin and insertion of the adductor longus m.?
Origin: Superior ramus of pubis
Insertion: linea aspera
What arteries supply blood to the adductor longus m.?
deep femoral artery and medial circumflex artery
Origin and insertion of the adductor brevis
Origin: Ramus of pubis
Insertion: Petineal line and linea aspera of femur
What is the arterial supply of the adductor brevis?
Obturator artery, Deep femoral artery, and medial circumflex femroal artery
What adductor muscles assist with flexion of the thigh?
Adductor brevis and Pectineous
What adductor muscles assist with medial rotation of the thigh?
Gracilis and Pectineus
Origin and insertion of the gracilis m.?
Origin: Ramus of pubis
Insertion: Medial surface of the tibia
What arteries supply blood to the gracilis muscle?
Deep femoral artery and medial circumflex artery
What is the action of gracilis m.?
Flexion of the leg and medial rotation of the thigh
What 3 muscles of the thigh insert onto the Pes anserinus?
Semitendonous, Gracillus, and Sartorius
What tendon does the Sartorius, Gracilis, and Semitendonous mm. insert into?
Medial surface of the tibia > Pes anseriuns
Player experiences hamstring muscle strain with proximal avulsion from what ?
