In the Standard Anatomical Position, the body is standing erect, facing the observer, the feet are together, and the arms are at the sides with the palms facing forward. This position is used as a reference to describe sites or motions of various parts of the body.

Directional Terms

Directional terms describe the positions of structures relative to other structures or locations in the body.

• Anterior/Posterior: Anterior refers to the front, or towards the head of the body, while Posterior refers to the back, or towards the tail.
• Dorsal/Ventral: Dorsal is towards the back, while Ventral is towards the belly.
• Superior/Inferior: Superior means above or closer to the head, while Inferior means below or closer to the feet.
• Medial/Lateral: Medial is towards the midline of the body, while Lateral is away from the midline.

Planes of the Body

The body can be divided into different planes:

• Sagittal Plane: This is a vertical plane that divides the body into right and left.
• Coronal Plane: This is a vertical plane that divides the body into anterior (front) and posterior (back) parts.
• Transverse Plane: This is a horizontal plane that divides the body into superior (upper) and inferior (lower) parts.
