Abduction
Movement of a body part away from the midsagittal plane
Acanthion

Anterior
Referring to the front or forward part of the body.
Anterior Posterior Projection
A projection in which the X - Ray beam travels from the front to the back of the patients body.
Axial Plane
A horizontal plane deviding the body in to superior and inferior portions.
Body Habitus
A term used to describe various body sizes and shapes.
Caldwell Method
A posteroanterior axial projection for head work requireing a 15 degree cauded angle.
Caudad ( Caudal )
Describing a central ray direction toward the feet.
Cephalad ( Cephalic )
Describing a central ray direction toward the head
Coronal Plane

Erect Position
A standing or seated upright body position.
