What are the three ways a neurotransmitter can influence a neuron?
A. Ionisation, conduction, osmosis
B. Excitatory, inhibitory or modulatory
C. Chemically, Ionisation, modulatory
D. Excitatory, conduction, modulatory

Neurotransmitters influence neurons in three ways: they can be excitatory, which promotes action potential firing; inhibitory, which decreases the likelihood of firing; or modulatory, which adjust the effects of other signals. Each type plays a vital role in the communicative functions of the nervous system. Understanding these influences is crucial for grasping how signaling works in the brain. ;

Neurotransmitters influence a neuron mainly in three ways: excitatory, which promotes action potential firing; inhibitory, which reduces firing likelihood; and modulatory, which adjusts other neurotransmitter effects. Each type plays an essential role in the brain's communication process. Therefore, the correct answer is option B. Excitatory, inhibitory or modulatory .
