- opposite of anterior
- dorsal because it’s relates to the back of the body

- towards the back or spine
- example: the vertebral column is dorsal to the aorta

A
- a plane that’s passes perpendicular to the long taxis of the body, dividing it into superior and inferior portions
- also called horizontal plane or cross-section
16
Q
Sagittal Plane
A
- a plane that passes from the front to the back through the body, dividing it into the right and left portion
