Q

The position with the body erect with the arms at the sides and the palm forward. The anatomic position is of importance in anatomy because it is the position of reference for anatomic nomenclature.Anatomic terms such as anterior and posterior, medial and lateral, and abduction and adduction apply to the body when it is in the anatomic position.
