More on the sciatic nerve — the prohibition against the “gid ha-nasheh” applies only to the sacrificial animals that are consumed (not a burnt-offering, but a peace-offering, for example). Though there are those who note that if you eat from a sacrificial animal that shouldn’t be eaten from – that will still be lashes, as compared to a fully-burnt offering, which would not levy a penalty for not removing the gid ha-nasheh. And note that a removed gid ha-nasheh would not be brought on the altar. Also, the gid ha-nasheh from the peace-offering — it should be swept to the drain, while the burnt-offering would entail putting it on the pile of ash in the middle of the altar. Which leads into a discussion of exaggeration in the Torah, by the prophets, and by the sages. But this was not the norm, and the Gemara provides the specific list of the exaggerations from these three sources.
