Anatomical Position
The position created by standing straight ahead and keeping both hands straight and palms open is called the anatomical position of the human being.
In this condition, the human body is divided into the imaginary levels which are-
1. Sagittal Plane or Median Plane: The longitudinal plane with the help of which the body can be divided into right and left equal parts along the median axis is called sagittal plane or median plane.
2. Coronal plane or frontal pnela (Coronal Plane or Frontal Plane): The longitudinal plane that intersects the medial plane at right angles and divides the body into the base and surface is called coronal plane or frontal plane.
3. Horizontal plane or horizontal plane (Horizontal plane): The transverse plane that extends through the navel of the human body and divides the body into upper and lower parts is called horizontal plane or horizontal plane.
