What is the opposite of chin?

There isn't a direct opposite of "chin" in the anatomical sense. However, depending on what you're looking for, some potential "opposites" could be:

* Top of the head: If you're thinking about the position on the body, the top of the head is the opposite end of the body from the chin.

* Back of the neck: If you're thinking about the direction of the body, the back of the neck is the opposite direction from the chin.

* Crown: This refers to the highest point on the head, which could be considered the opposite of the chin in terms of location.

It's important to clarify what you mean by "opposite" for a more accurate answer.
