stimulation of a receptor initiates what event?

stimulation of a receptor initiates multiple signal pathways. Specific responses depend on the type receptor.

That receptor cell fires, sending an electrical impulse down its length. The type and strength of the stimulation will effect how frequently the transducer (a cell that changes energy from one form to another) fires. However, the strength of the impulse will always be the same for any particular cell.

The type of transducer — in the eye, skin, nose, ears and so on — will determine which other cells the impulse effects.

I hope this helps a little more. Thanks for asking.

which vein drains the brain

it depends on if you are using your cns or pns
