week two (august 30) of bio 203 was interesting as we got to see the sciatic nerve! although not in line with grant's dissector, it was a fascinating dissection and very interesting to palpate. surprisingly, it is approximately the same size as the spinal cord, which means that after it diverges from the spinal cord it gets larger, unlike most spinal nerves.
during our class time, we further dissected the back to clean superficial muscles and reflect intermediate and deep back muscles. next, we cleaned several structures in the suboccipital region. finally, we were able to cut the laminae of the vertebrae to reveal the spinal cord. this was fascinating! it took us at least an hour just to saw and chisel the laminae after they were exposed. it gave me a new appreciation for how protected our spinal cord is.
