Where, my friend, is this Lumbar Region?
Well, friend… It refers to one of the six regions of the axial skeleton:
And, it’s a very flexible section of the axial skeleton (complementary to the appendicular skeleton). For example… In the torso (thorax plus abdomen), the thorax is surrounded by the ribcage; providing a lot of protection for the soft squishy bits (the lungs, the heart, the stomach, spleen, etc.).
