ANTERIOR COMPARTMENT:

Between medial and lateral intermuscular septa.

Contents:

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

Review attachments and actions of these muscles.

• Femoral vessels
• Femoral nerve

MEDIAL COMPARTMENT:

Separated from the anterior compartment by medial inter muscular septum.

There is no septum separating it from posterior compartment

Contents

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

Separated from the anterior compartment by lateral intermuscular septum.

Contents:

• 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.

Note:

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
