Human Body Anatomical Planes & Sections

Body Planes

They are the hypothetical geometric planes that are used to divide the body into sections. Body Planes are commonly used in both human and zoological anatomy to describe the location or direction of bodily structures.

Fig. Anatomical Planes of a body

1. Sagittal or median plane divides the body into sinister and dexter (left and right) sides.

2. Coronal or frontal plane divides the body into dorsal and ventral (back and front) portions.

3. Transverse or axial plane divides the body into superior and inferior (head and tail) portions.

Some Anatomical Terms

1. Anterior = In front of

2. Posterior = In back of

3. Dorsal = Pertaining to the back

4. Ventral = Pertaining to the front

5. Lateral = away from the midline of the body

6. Medial = towards the midline of the body

7. Sinister = on the left side

8. Dexter = on the right side

9. Proximal = near to the point of origin or attachment

10. Distal = away from the point of origin or attachment

11. Superior = Above

12. Inferior = Below

13. Ipsilateral = on the same side
