Confused

I am confused about one thing in the game and was hoping someone could explain to me the differences.

In Emergency tab, you can build Doctors offices etc, then you unlock Hospitalization, with trauma centre. But further to the right you have Traumatology tab, with traumatology offices.

AM i right assuming that Trauma CENTRE, is where the ambulances transport patients who has collapsed, been in accidents etc, while Traumatology is a whole different clinic, and emergencies will not be put here?

Trauma centre is A&E, ER, ED. Ambulances take patients there

Traumatology takes patients that have been hit by lightning, bitten by snakes, had electric shocks, been shot, etc
