Compartments Of the Thigh


Between medial and lateral intermuscular septa.



  • Quadriceps femoris
  • Hip flexors (iliacus, psoas major, pectineus and sartorius)

Review attachments and actions of these muscles.

  • Femoral vessels
  • Femoral nerve

Separated from the anterior compartment by medial inter muscular septum.

There is no septum separating it from posterior compartment


  • Adductor muscles including gracilis
  • Obturator nerve
  • Profunda femoris artery
  • Obturator artery

posterior Compartment  

Separated from the anterior compartment by lateral intermuscular septum.


  • Hamstring muscles (name them and review their attachements and actions)
  • Sciatic nerve and its branches
  • No artery. Receives blood from Profunda femoris through its perforating branches which form a longitudinal anastomosis.


Short head of bicep femoris is not a true hamstring because:

  • It arises from linea aspera and not ischial tuberosity.
  • It is innervated by common peroneal and not tibial nerve.
  • It flexes the knee but does not extend the hip joint.

  Adductor Magnus is functionally divided into two:
1. The ischial (harmstring) component:

  • Arises from the ischial tuberosity
  • Innervated by tibial nerve
  • Extends the hipjoint

2. The pubic (adductor) component:

  • Arises from the pubis
  • Innervated by obturator nerve
  • Adducts the hip joint
