Anatomical Position Standing straight, head forward, palms facing front. Why is it important to have a standard position when looking at anatomy?

Orientation and Directional Terms Using the textbook, complete the handout “Anatomical Terminology & Practice”. You must write a definition, draw a picture, and write a sentence using the words. You may not use the same sentence as the book has for the terms!
