Study Notes

Anatomical Position and Body Orientation

Anatomical position: body upright, facing observer, feet flat and forward, arms at sides, palms facing forward.
Supine position: lying face up.
Prone position: lying face down.

Directional Terms

Directional terms describe the location of body parts relative to each other.
Anterior: at or near the front of the body.
Posterior: at or near the back of the body.
Midline: imaginary line dividing the body into right and left halves.

Additional Directional Terms

Medial: nearer to the midline.
Lateral: away from the midline.
Superior: toward the head; upper part of a structure.
Inferior: nearer to the feet; lower part of a structure.
Deep: away from the body's surface.
Superficial: close to the body's surface.
Proximal: nearer to the origination of a structure.
Distal: farther from the origination of a structure.

Planes of the Body

Planes are imaginary flat surfaces that segment the body.
Frontal (Coronal) Plane: divides the body into anterior (front) and posterior (back) portions.
Transverse Plane: divides the body into superior (upper) and inferior (lower) portions.
Sagittal Plane: divides the body vertically into right and left portions.
Midsagittal Plane: divides the body vertically into equal right and left sides.
Parasagittal Plane: divides the body vertically into unequal right and left sides.
Oblique Plane: passes through the body at an angle.

Summary of Key Terms

Anterior, Posterior, Midline, Superior, Inferior, Lateral, Medial, Proximal, Distal, Superficial, Deep.
Frontal, Transverse, Sagittal, Midsagittal, Parasagittal, Oblique are the commonly referenced planes.
