The word apex lets name the top end or the tip of something… the apex of a mountain, the apex of a bed. It will then be the highest part of the thing or object in question.
On the other hand, the word is also frequently used to designate a very, very small part, which turns out to be practically insignificant due to the small dimensions that it has.
It should be noted that it is a term normally used with a negative sense, that is, when someone wants to give an account of how little another is willing to do something usually uses the word apex to refer to it. Don't even think that she will have an iota of compassion and will help you in this difficult moment, María is like that, very selfish.
On the other hand, at the request of the Botany, apex is the term that allows to name the tip or upper end, either of a leaf, of a fruit, among others. In the specific case of a leaf, we find the organic apex, which is where the organ could grow distally and on the other hand the geometric apex, which is the most distant point from the base.
On odontology, more especially to the branch of the endodontics, which is the one that deals with the treatment of root canals, the apex turns out to be the terminal part of a tooth root.
