Lateral is sideways so vertical, up and down, would be opposite.
Lateral
The football player made a lateral play.A lateral move is to or from the side.
Medial - pertaining to the middle or midline
A force acting in a horizontal direction, such as wind, earthquake, or soil pressure against a foundation or a retaining wall.
The opposite reaction of to sink (in liquid) is to float.However the opposite motion sink (move lower) would have the opposite rise.
The opposite of lateral is medial.
In a strike-slip fault, rocks on opposite sides move horizontally past each other in opposite directions or at different rates. This type of fault is categorized as either left-lateral or right-lateral based on the direction of movement when facing the fault.
The opposite of medial is lateral. Medial refers to a location closer to the midline of the body, while lateral refers to a position further away from the midline.
This process of rocks moving in opposite directions on opposite sides of a fault is known as strike-slip faulting. The movement can be either left-lateral (sinistral) or right-lateral (dextral), depending on the relative lateral displacement of the blocks. If the rocks move in the same direction but at different rates, it may indicate differential movement caused by friction variations along the fault plane.
Lateral
The sides of a strike-slip fault move horizontally past each other in a side-to-side motion. This movement can be either left-lateral, where the block opposite an observer moves to the left, or right-lateral, where the block moves to the right.
The lateral faces will be parallelograms, and the opposite faces will be congruent. In a right prism, the lateral faces will be rectangles.
When rocks on opposite sides of a fault move in the same direction at different rates, it results in a strike-slip fault. This type of fault occurs when there is horizontal motion along the fault line. The two main types of strike-slip faults are left-lateral and right-lateral, depending on the direction of movement when facing the fault.
Contra- means against or opposite, and lateral means the edge away from the body. So contra-lateral means opposite outer edge. Conralateral does not control anything.

I would guess lateral maybe?
