The reason there is a fire axe on the flight deck is simply in the eventuallity of a hijacking the pilots can defend the plane. That's not the official line but that's the reality.
The front of the aircraft AKA: The Cockpit
Where the cockpit is near the front, the opposite end of an aircraft is the tail. (Where the cockpit is on the top, the opposite is the undercarriage. In a passenger aircraft, the opposite of the cockpit or control area is the passenger area, or cabin.)
The cockpit in an aircraft is the part where the pilot sits.
the cockpit
In the cockpit of the aircraft. Typically near the nose of the craft.
The cockpit is where the pilot controls the aircraft.
Flightdeck shifters in an aircraft cockpit are used to control various functions of the aircraft, such as adjusting the throttle, changing the aircraft's altitude, and controlling the direction of the aircraft. These shifters are typically located on the center console of the cockpit and are designed to be easily accessible to the pilot. They often have different shapes and sizes to differentiate their functions, and may include buttons or switches for additional control options.

Its the area of a aircraft that has the controls and operational systems to fly the craft
A canopy is the name for the clear plexiglass cover of the cockpit.
They are called "yokes" or in airbus aircraft "joysticks".
I know in a non-military plane the cockpit can get very hot inside when not flying because the cooling of the cockpit is brought by the highspeed movement of the aircraft. So I would imagine that it is because its uncomfortable in the heat if the cockpit is closed.
