Apex (headdress)
The apex was a cap worn by the flamines and Salii at Rome. The essential part of the apex, to which alone the name properly belonged, was a pointed piece of olive-wood, the base of which was surrounded with a lock of wool. This was worn on the top of the head, and was held there either by fillets only, or, as was more commonly the case, was also fastened by means of two strings or bands, which were called apicula (Festus, s.v.), or offendices (Festus, s.v.), though the latter word is also interpreted to mean a kind of button, by which the strings were fastened under the chin (cf. Serv. ad Virg. Aen. ii.683, viii.664, x.270).
The flamines were forbidden by law to go into public, or even into the open air without the apex (Gellius x.15), and hence we find the expression of alicui apicem dialem imponere used as equivalent to the appointment of a Flamen Dialis (Livy vi.41). Sulpicius was deprived of the priesthood, only because the apex fell from his head whilst he was sacrificing (Valerius Maximus i.1 §5).
Apex (mollusc)
In anatomy, an apex (adjectival form: apical) is part of the shell of a mollusk. The apex is the pointed tip (the oldest part) of the shell of a gastropod, scaphopod, or cephalopod.
Gastropods
The word "apex" is most often used to mean the tip of the spire of the shell of a gastropod. The apex is the first-formed, and therefore the oldest, part of the shell.
To be more precise, the apex would usually be where the tip of the embryonic shell or protoconch is situated, if that is still present in the adult shell (often it is lost or eroded away).
Coiled gastropod shells
The phrase apical whorls, or protoconch, means the whorls that constitute the embryonic shell at the apex of the shell, especially when this is clearly distinguishable from the later whorls of the shell, otherwise known as the teleoconch.

Limpet-like gastropod shells
Where this feature is present, the space under the apex of a patellate or patelliform (limpet-like) gastropod shell is called the apical cavity.
Apex, North Carolina
Apex is a town in Wake County, North Carolina and a suburb of Raleigh. The U.S. Census Bureau estimates the town's population to be 43,907 as of July 1, 2014.

History
The town of Apex was incorporated in 1873, named for its location as the highest point on a portion of the Chatham Railroad which ultimately extends between Richmond, Virginia and Jacksonville, Florida. Apex grew slowly through the succeeding decades, despite several devastating fires, including a June 12, 1911 conflagration which destroyed most of the downtown business district. The town center was rebuilt and stands to this day, now one of the most intact railroad towns in the state. At the heart of town stands the Apex Union Depot, originally a passenger station for the Seaboard Air Line Railroad and later home to the locally-supported Apex Community Library. The depot now houses the Apex Chamber of Commerce.

Fictional character biography
Apex is one of sixteen teenagers kidnapped by Arcade who forces them to fight each other to the death in his latest version of Murderworld. She is part of the Braddock Academy group (consisting of Kid Briton, Anachronism, Bloodstone and Nara) which is joined by Death Locket despite death threats from Kid Briton and Nara. Death Locket started bonding with Apex as she introduces her to the rest of the Braddock Academy.
There is discord in the Braddock Academy's ranks as Anachronism and Kid Briton get into an argument. An earthquake then separates Bloodstone and Anachronism from Apex, Nara, Kid Briton, and Death Locket. Death Locket goes dormant as her cybernetics take over and she blasts Nara off a cliff and into the ocean. Kid Briton is enraged by this and tries to kill her until Apex orders him not to, revealing that she knew about his affair with Nara back at the Braddock Academy and that "we're here now and I'm done sharing."
Apex (geometry)
In geometry, an apex (Latin for 'summit, peak, tip, top, extreme end') is the vertex which is in some sense the "highest" of the figure to which it belongs. The term is typically used to refer to the vertex opposite from some "base."
Isosceles triangles
In an isosceles triangle, the apex is the vertex where the two sides of equal length meet, opposite the unequal third side.
Pyramids and cones
In a pyramid or cone, the apex is the vertex at the "top" (opposite the base). In a pyramid the vertex is the point that is part of all the lateral faces, or where all the lateral edges meet.
