The sickbay seems to have the equipment of a basic small hospital (beds, stretchers, IV's), but is relatively spartan otherwise. It is also equipped with a machine similar to a magnetic resonance imaging scanner.
According to Lee Adama, the sickbay is also designed as a disaster shelter in the event of a ship catastrophe (Valley of Darkness).
Galactica also possesses a morgue, which can be accessed through Baltar's lab ("The Farm", "Sacrifice"). The lab itself is located in the starboard forward section of the ship (Six Degrees of Separation).
