Which term refers to cells that utilize acetylcholine as their synaptic transmitter?

The term that refers to cells utilizing acetylcholine as their synaptic transmitter is "cholinergic." This designation is derived from the neurotransmitter acetylcholine, which plays a key role in transmitting signals in both the peripheral and central nervous systems. Cholinergic neurons are responsible for a variety of functions, including muscle movement and the transmission of signals in the autonomic nervous system.

In contrast, other terms provided do not specifically relate to acetylcholine. "Adrenergic" refers to cells that respond to adrenaline (epinephrine) or noradrenaline (norepinephrine), which are key neurotransmitters in the body's response to stress. "Neurogenic" is a broader term that relates to anything arising from nerves, without specifying the type of neurotransmitter involved. "Synaptic" refers to the junction between two neurons but does not identify specific neurotransmitters. Thus, "cholinergic" is the accurate term associated with the use of acetylcholine in synaptic transmission.
