The Lower Limb

The Lower limb has the same general plan of the upper limb BUT the flexor compartment is located posteriorly and the extensor compartment is located anteriorly.

To get an insigt into the structures and their function, I recommend the cross sectional approach!

For example, the above illustration is a cross section in the mid thigh region. This section demonstrates three distinct muscle groups; the anterior group (Knee extensors) that are mainly supplied by the femoral nerve. The posterior group or what is known as the hamstring muscles are supplied by the sciatic nerve. The medial compartment is accomodated by adductor muscles and supplied by the obturator nerve. We use our addutors mainly when we ride on a horse!!!!!

Now here is my question where is the abductors of the thigh?
