  anatomy to the human anatomy, the feet are

Helpful hints

• When dissecting your pig, keep in mind that
  dissecting is not just about cutting into your
  pig but is also about learning about the world
  around you.
• When using your dissecting needles, remember that
  they are useful in tracing blood vessels and
  nerves, and in separating muscles.
• Study the organs as they are exposed.
• Leave the blood vessels connected to the organs
  intact.
• Confirm the names and locations of body parts on
  your specimen.
• When using scissors, advance with rounded end,
  not the pointed end.
• Move organs aside with a blunt object.
