Which part of the frogs nervous system can be observed in it abdominal cavity and hind leg?
Depending on exactly how much of the abdominal cavity you open and how deep you go, you might be able to see the base of the spinal cord, which contains the nerves that send impulses to and from the brain and muscles of the legs. In the legs, the only part of the nervous system you might be able to see are the fibers that come from the spinal chord and innervate the muscle (which makes it contract and relax). Theoretically you could also see the fiber bundle which innervates the skin and makes him able to sense touch, however that would have to be a pretty sweet dissection.
