  1. Anatomical Position Standard 1 Objective 8

  2. What is it? The anatomical position is: “the universal accepted starting point used to describe or analyze anatomical terms or movement.” To be in correct anatomical position, the body must meet 3 criteria: • Upright, standing position • Face and feet pointing forward • Arms at the side, palms facing forward But how do we use the anatomical position to describe direction and planes?

  3. Anatomical Planes -relate to positions in space and found at right angles to each other -these planes can be positioned on specific parts of the body Frontal(Coronal) -vertical; splits the body into front and back halves

  4. Anatomical Planes -relate to positions in space and found at right angles to each other -these planes can be positioned on specific parts of the body Sagittal -vertical; splits the body into left and right halves

  5. Anatomical Planes -relate to positions in space and found at right angles to each other -these planes can be positioned on specific parts of the body Transverse -horizontal; splits the body into upper and lower halves

  6. Body Position Terminology • The following terms will become like a second language for you. These terms are used to describe position of the body and will be used extensively when we talk about muscles and bones Medial- towards the midline(center) of the body Lateral- away from the midline of the body Superficial - on or close to the surface of the body Deep - farther away from the surface of the body

  7. Superior- towards the top of the body (cranial) Inferior- towards the bottom of the body (caudal) Anterior- towards the front of the body (ventral) Posterior- towards the back of the body (dorsal) Proximal- situated closest to the point of attachment Distal- situated farthest from the point of attachment
