Superior

Superior: An anatomical direction that refers to a structure located "above" another structure. Generally, this term is used to describe the relative position of a structure when the body is in the anatomical position. For example, the nose is superior to the mouth.

• Note that this term does not refer to "on top of", or "superficial to." For example, superior to the rectus abdominis is the xiphoid process, sternum, and ribcage, but superficial to the rectus abdominis is the rectus sheath and skin.
  

The opposite of superior:

• Inferior
