How to approach learning about compartments?

• Know the nerves, arteries, veins, and lymphatic vessels that supply a compartment.
• Know the muscles of a compartment and the primary actions of the muscle group within a compartment.
• You may want to divide a compartment into thirds when discussing vascular supply.
• Once you know the nerves and vessels of a compartment you can make quick inferences about the neurovascular supply to structures within that compartment.
• Know about exceptions to the general organization of a compartment (short head biceps).
• Knowledge about the general organization of a compartment allows quick inference about the actions, innervations, and vasculaturization of structures within the compartment.
• Refine your knowledge about exceptions to the general organization of a compartment. Are there hybrid muscles?

Example: The posterior compartment of the thigh

1. Nerves
   • The sciatic nerve - how bad can it be?
   • Refine your knowledge. There is a tibial part and a peroneal part.
2. Vasculature
   • Arteries and veins - think about regional supply and then know what is in the region
     • Upper third - did you learn the cruciate anastomosis? Ditto for upper posterior thigh.
     • Middle third - perforating aa
     • Lower third - poplitieal a
     • Notable differences between the anatomy of arteries and veins
   • Lymphatic vessels
     • superficial - know about lymphatic divides, clinical significance of drainage to popliteal nodes
     • deep -
3. Muscles
   • Collective action - extend the hip and flex the knee
     • Any that do not extend the hip - short head biceps
     • Any that do not flex the knee - posterior adductor magnus
   • Which do and do not qualify as hamstrings and why
   • Be aware of hybrid muscles.
     • Short head of biceps is innervated by peroneal part of sciatic. The hamstrings are innervated by the tibial part of sciatic.
   • Refine your knowledge
     • semimembranosus and semitendinosus, by virtue of inserting onto the medial tibia, medially rotate the leg
     • biceps femoris, virtue of inserting onto the lateral fibula/tibia laterally rotates the leg

I am studying 18 hrs/day and it just does not sink in. What can I do?

• Be tough
• Studying for the laboratory examination
• Studying for the lecture examination
