Question

Neurons releasing acetylcholine are

• A. adrenergic
• B. cholinergic
• C. Both A and B
• D. None of the above

Answer 1

The correct option is B cholinergic

Neurotransmitters are the molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles.
The first neurotransmitter to be discovered was a small molecule called acetylcholine. Cholinergic is a term used to refer to the molecule acetylcholine. It is usually employed to define neurons, receptors or synapses that use acetylcholine. For instance, a cholinergic neuron is a neuron that releases acetylcholine, and a cholinergic receptor is a receptor to which acetylcholine binds.
Hence neurons releasing acetylcholine are known as cholinergic and those releasing adrenaline are known as adrenergic.
