Where can you see the canals running down a pig leg?

The canals running down a pig leg can be observed in the anatomical structures of the pig, specifically within the bones and soft tissues of the leg. These canals include blood vessels and nerves that run through the leg, facilitating circulation and innervation. In culinary contexts, when butchering a pig leg, these structures may be seen in the cross-section of the leg. Additionally, studying the leg in a veterinary or anatomical context would reveal these canals in detail.
