The BF491M is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BF491M transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.
The BF491M transistor symbol shows an arrow from the emitter into the base. This means that the current flows from emitter to collector terminal.
