It really is and there is a shit tonne of information regarding neural signal transport and muscular response, the NMJ and Corticospinal structures are incredibly important, I also find that discussing how nerves are descending (Which I mean that the nerves along the spine that correspond to a particular muscle group do not align perpendicular so that the Nerve origin is always more superior relative to the muscular group's nerve ending), and hence why Spinal Taps are typically done in L4-L5 to avoid paralysis/nerve damage of organs and any higher structures. Also I think the Cauda Equina is a pretty awesome point to show explicitly the density of nerves packed into the spinal cord.
