The text indicates that the digestive tract in vertebrates is ventral to (beneath) the backbone. Yet our digestive tract is in front of our backbone, which is still considered ventral. Why is this an appropriate statement?
◦ Humans have entirely different organ arrangements than any other vertebrates so words like ventral take on entirely different meanings.
◦ Terms like ventral that describe spatial relationships between structures are based on a common body plan of a creature who walks on four legs and in that case the digestive track would be ventral to the backbone.
◦ It is wrong to say that our digestive track is ventral to the backbone.
