medial
away from the mid-line of the body
lateral

proximal
furthest from point of attachment to trunk
distal
a vertical plane that divides the body or organ into anterior and posterior parts.. When taken through the trunk, the anterior portion contains the chest and the posterior portion contains the back and buttocks.
What color portion?
coronal (frontal) plane
purple
divides the body or organ into superior and inferior parts. If taken through the middle of the trunk, the superior portion contains the chest and the inferior protion contains the abdomen.
