This is an incredible database of muscles and the nerves that innervate them. As a patient, it gives you a little more of idea of where the pain originates. For example, if the inside of your hip is sore and the pain radiates to the outside area of your knee, that follows the line of the Sartorius muscle. This muscle is innervated by the Femoral nerve at the root of L2, L3. This muscle functions to adduct the thigh (bring it in towards the midline), flexes the leg (brings it forward), and helps to rotate the leg medially (turn the leg inwards).
This database gives you all that information. YOU know what movements cause you pain. YOU know where you feel it. This doesn’t make any of physicians but when you are trying to tell your neurosurgeon where it hurts, it can help to isolate the area.
As a biologist, I am impressed with the amount of work that went into this table. It covers the whole body. In my earlier years, this would have been an invaluable study aid in human anatomy and the dissection lab.
