Final answer:
Superior and inferior are used to describe positions in relation to other body parts.
Step-by-step explanation:
The terms 'superior' and 'inferior' are used to describe positions or locations in the body in relation to other parts.
In anatomical terms, 'superior' refers to a position above or higher than another part of the body, while 'inferior' refers to a position below or lower than another part of the body.
For example, the head is considered superior to the chest, while the feet are considered inferior to the knees.
