A bressummer beam carries loads from above but has no window or door below it. Therefore its allowable deflection (long term or short loads) can be greater. A lintel on the other hand has a window or door below it and requires less deflection to ensure that the operation of the window/door is not compromised.
The "inverted arch" is used when a sideways, or inward load, is to be resisted. The "common arch" supports a vertical load.
post and lintel construction

A lintel is a horizontal architectural member spanning above an opening, such as a doorway or an arch. A finial is a decorative piece that finishes off the top of the lintel. It could also be placed above the vertical posts on opposite ends. Think of the finial(s) as "final finish(es)."
An arch or lintel supported by corbels, or protrusions from a wall.
Given the same construction materials (originally stone) an arch is tremendously stronger than a post and lintel. You can pile much more weight on an arch without causing it to collapse, as compared to the post and lintel; the lintels break much more easily.
The arch's weight is transfered over instead of straight across.
A trilithon or trilith) is a structure consisting of two large vertical stones (posts) supporting a third stone set horizontally across the top (lintel). Like that of a door way
A lintel is over a window or door and a beam is usually under the structure of the building, either the roof or the floor.

It's not a question of opening size but a question of loading over the opening. No load, no lintel. If a 12 inch opening is capped with a 16" block, the block is the lintel. If an opening is between wall studs there is little need for anything that would be called a lintel. Anouther name for a lintel is a header. There is usually some kind of header over an opening. A lintel's size and integrity is determined by the load it will support.

An arch is a curved structure that provides support, while a sole is the bottom part of a shoe or the underside of a foot. The arch helps distribute weight and absorb shock, while the sole provides cushioning and protection for the foot.
a lintel, or a lintel beam.
The term crossbeam is an alternative for lintel.
