Synchronizers let you shift gears using the clutch.
Overview
Synchro is two cones pressed together until the two shafts run the same speed:
Each gear has a syncho face (external cone) machined with it
The hub is spring loaded so when you move the shifter partway, it presses the baulk ring (internal cone part) against the gear.
When they have slow down to the same speed, the shifter will move all the way in. It happens very quickly, unless the synchros are worn and not working well.
Synchro is basically:
Coupling with hub Baulk rings and gear faces
Coupling with hub. Left: assembled. Right: not assembled

Each synchro set services two gears (arrows). Center arrow points to the Coupling Sleeve

The Coupling Sleeve is what the shifter moves.
The hub is keyed to the mainshaft, so the sleeve rotates constantly in the Shift ForK while the car is moving.
The spring lets the hub move side-to-side inside the Coupling Sleeve, but not move too far. On this one there is a total of about 1/4" (5mm) total movement possible.
56-Series Transmission
FS5C56A 5-speed has very different synchros from other A-series transmissions. It has "C" type synchros (the "C" in FS5C56A) which are very different
