Clinical gross anatomy of the head
In the pig the head and neck is large. The pig’s head is dominated by its large snout (rostrum) which it uses as an rooting tool. In combination with the muscles of the neck the snout becomes a major exploratory tool. Pigs are extremely destructive and will kill and clear forests and homes when allowed. |
