Inferior

Inferior: An anatomical direction that refers to a structure located "below" 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 chin is inferior to the mouth.

• Note that this term does not refer to "under", or "deep to". For example, inferior to the lower segment of the rectus abdominis is the pubic symphysis. Deep to the rectus abdomonis are the peritoneum and internal organs.
  

The opposite of inferior:

• Superior
