Neurology appointment: what to expect?

Hey everyone.
Does anyone know—or can someone walk me through—what actually happens during a neurological exam? Like, what symptoms are they even looking for?
When the doctor starts tapping on your knees or wrists with those little reflex hammers, what's the goal there? What kind of reaction are they checking for when they tap or test sensation? Does it actually hurt, or is it just... nothing?
What kind of conditions are they trying to pin down with that stuff?

Thanks in advance... peace.

Look, I’m not a doctor or anything, but let me break this down for you. What they’re doing is basically just a visual check to see if your coordination and reflexes are actually firing right—kind of like how a cop makes you walk that straight line on the sidewalk to see if you've had too many beers, except here, a neurologist is going to track their finger moving toward your eyes to see if your gaze follows correctly. If you don't feel a hit, it's not that it doesn't hurt, it's just that you aren't sensing the stimulus, which isn't ideal, but seriously, don't sweat it; you're in good hands. If they need to dig deeper, they'll just run some standard stuff like a CT scan, an MRI, or maybe an EEG. Honestly, the worst part is probably just the little sting from the needle when they draw your blood, so please, just try not to panic.
