Outline of Human Anatomy for medical students from foreign nationality Department of Human Anatomy 1 Introduction The Anatomical Position A person in the anatomical position is standing erect (or lying supine as if erect) with the head, eyes, and toes directed forward, the upper limbs by the sides with the palms facing forward and the lower limbs together with the digits (toes) pointing forward. Anterior and posterior Superior and inferior Medial and lateral Intermediate. Between two structures Proximal and distal Superficial and deep External (outer) and internal (inner) Unit 1 Lower Limb The anatomical planes Anatomical description is also based on four imaginary planes (median, sagittal, coronal, and horizontal) that pass through the body in the anatomical position. The median plane: This is the imaginary vertical plane passing longitudinally through the body, dividing it right and left halves. The median plane intersects the surface of the front and back of the body at the anterior and posterior median line, respectively. The sagittal planes: These are imaginary vertical planes passing through the body parallel to median plane. These planes are named after the sagittal suture of the skull, with which they are parallel. The sagittal plane the passes through the median plane of the body is often referred to as the median sagittal plane, or the midsagittal plane. The coronary planes: These are imaginary vertical planes passing through the body at right angles to median plane, dividing it into anterior and posterior part. These planes are named after the coronal suture of the skull, which is coronal plane. The coronal plane is also referred to as the frontal plane. The horizontal planes: these are imaging planes passing through the body at right angles to both median and coronal planes. It may help to remember that they are parallel to horizon. A horizontal plane divides the body into superior and inferior parts. The horizontal plane is also referred to as the transverse plane.
