HIP ADDUCTOR MUSCLES

                                     

                                        ADDUCTION MUSCLES

Adductor magnus -- The adductor magnus (r, I), a muscle of the adductor group in the medial compartment of the thigh, is a large triangular muscle situated on the medial side of the thigh. 

The adductor magnus has multiple osseoaponeurotic openings formed by tendinous arches attached to the bone to allow for the passage of vessels.

Origin: Inferior ramus of the pubis, inferior ramus of the ischium, and tuberosity of the ischium 

Insertion: Adductor tubercle on the medial condyle of the femur; medial lip of the linea
 aspera


RED FOR ORIGIN 
BLUE FOR INSERTION

Innervation: Obturator nerve (L03, L04), and branch from sciatic 

Action: Adducts the thigh powerfully:rotates the thigh medially 

Blood supply: Deep femoral artery

Pectineus--
                       

The pectineus (r, I), a muscle in the medial compartment of the thigh, is a flat, quadrangular muscle situated at the anterior part of the upper and medial aspect of the thigh.



Origin: Pectineal line or superior ramus of the pubis

Insertion: Posterior surface of the femur on a rough line leading from the lesser trochanter to the linea aspera

Innervation: Femoral nerve (L02, L03, LO4) and occasionally the obturator nerve

 Action: Adducts thigh; flexes thigh; externally (laterally) rotates thigh

Blood supply: Medial circumflex femoral artery



Adductor longus--  


The adductor longus , a muscle of the adductor group in the medial compartment of the thigh,

is the most superficial of the three adductors;

 it is a triangular muscle, lying in the same plane as the pectineus.



Origin: Front of the pubis, at the angle of junction of the crest with the symphysis

 Insertion: Linea aspera, between the vastus medialis and the adductor magnus

 Innervation: Obturator nerve (L03, LO4), and branch from sciatic

Action: Adducts the thigh powerfully; rotates the thigh medially

 Blood supply: Deep femoral artery




Adductor brevis-- 

The adductor brevis (r, I), a muscle of the adductor group in the medial compartment of the thigh, is somewhat triangular in form.



It is situated in front of the adductor magnus and immediately behind the adductor longus and pectineus.



Origin: Narrow origin from the outer surfaces of the superior and inferior rami of the pubis

 Insertion: Into the line leading from the lesser trochanter to the linea aspera and into the upper part of the linea aspera

Innervation: Obturator nerve (L03, L04), and branch from sciatic nerve

 Action: Adducts the thigh powerfully; rotates the thigh medially

 Blood supply: Deep femoral artery

Gracilis--



The gracilis, a muscle in the medial compartment of the thigh, is the most superficial muscle on the medial side of the thigh.
 It is one of the three muscles the make up the pes anserinus.



Origin: Lower half of the pubic symphysis and the upper half of the pubic arch

 Insertion: Medial surface of the superior shaft of the tibia via a common tendon of the pes anserinus

Innervation: Obturator nerve (L03, L04)

 Action: Adductor of the thigh; flexes the leg at the knee and rotates it medially (inward)

 Blood supply: Obturator artery
