NEET PG DENTAL EXAM

Detailed explanation-1: -Instead, a given neurotransmitter can usually bind to and activate multiple different receptor proteins. Whether the effect of a certain neurotransmitter is excitatory or inhibitory at a given synapse depends on which of its receptor(s) are present on the postsynaptic (target) cell.

Detailed explanation-2: -If the neurotransmitter is able to work on the receptor site, it triggers changes in the receiving cell. Sometimes neurotransmitters can bind to receptors and cause an electrical signal to be transmitted down the cell (excitatory).

Detailed explanation-3: -Neurons in the CNS generally receive inputs from multiple afferent sources. These afferent systems seldom all use the same neurotransmitter, so most central neurons are required to express multiple neurotransmitter receptors.
