Study Notes
Anatomical Position
- The body is standing erect.
- The face is looking forward.
- The upper limbs hang by the sides.
- The hands are facing forward.
- The lower limbs are parallel.
Supine Position
- The body is lying horizontal.
- The face and body are facing upward.
Prone Position
- The body is lying horizontal.
- The face is looking downward.
Anatomical Planes
- Median Plane: A vertical plane passing through the center of the body, dividing it into two equal halves.
- Paramedian Plane: A vertical plane dividing the body into two unequal halves.
- Coronal Plane: A vertical plane perpendicular to the median plane, dividing the body into anterior and posterior parts.
- Transverse Plane: A horizontal plane dividing the body into upper and lower parts.
Anatomical Terms of Position
- Median: A structure lies in the median plane.
- Medial: A structure lies nearer to the median plane.
- Lateral: A structure lies away from the median plane.
- Superior: A structure is close to the upper end of the body.
- Inferior: A structure is close to the lower end of the body.
- Anterior: A structure is nearer to the front.
- Posterior: A structure is nearer to the back.
- Superficial: A structure is nearer to the surface.
- Deep: A structure is away from the surface.
- Internal: A structure is inside an organ or cavity.
- External: A structure is towards the outer aspect of the organ.
- Proximal: A structure is nearer to the trunk.
- Distal: A structure is away from the trunk.
- Ipsilateral: A structure is on the same side.
- Contralateral: A structure is on the opposite side.

Summary
- The anatomical position is a standardized reference point used for describing anatomical structures.
- Anatomical planes divide the body into sections for study and understanding.
- Directional terms help with precise communication about the location of structures within the body.
- Median, Lateral, Medial: Relative position to the midline
- Superior, Inferior: Relative position along the vertical axis
- Anterior, Posterior: Relative position along the front-back axis
- Superficial, Deep: Relative position to the surface
- Proximal, Distal: Relative position to the attachment point of a limb
- Ipsilateral, Contralateral: Relative position on the same or opposite sides of the body
- Specific terms are used to describe locations on limbs: radial, ulnar, tibial, fibular, palmar, dorsal, plantar, etc.
