Describe embryologically why the upper limbs and lower limbs have opposing flexor and extensor compartments in the body. Why are the flexors and extensors on opposing anterior and posterior compartments?

o Limbs will rotate in opposite directions o Upper limb will rotate 90 degrees laterally (thumb is out laterally) = extensor muscles are posterior compartment o Lower limb will rotate 90 degrees medially (big toe is medial) = extensor muscles are in the anterior compartment
