What is the difference between cholinergic and adrenergic lines?
The main difference between the two is their neurotransmitters. For the cholinergic line, acetylcholine (ACh) is used while the adrenergic line makes use of either norepinephrine or epinephrine (also known as adrenaline); no wonder the adrenergic line came to be named as such because adrenaline is involved.
What are the receptors of the cholinergic system?
These receptors are regarded as intropic and metabotropic and are activated by the neurotransmitter Acetylcholine (ACh). Acetylcholine neurotransmitters bind to the muscarinic and nicotinic receptors, the two main cholinergic receptors to carry out its functions. The cholinergic system drives the digest and rest response of the body.
What is the difference between Nic nicotinic and muscarinic receptors?
Nicotinic receptors bind to nicotine and muscarinic receptors binds to muscarine. The main difference between adrenergic and cholinergic is that adrenergic involves the use of neurotransmitter adrenaline and noradrenalin whereas cholinergic involves the use of neurotransmitter Acetylcholine.

What is the difference between adrenergic and muscarinic receptors?
Muscarinic receptors respond to the binding of ACH, and may have an excitatory or inhibitory effect. Adrenergic receptors are located on most sympathetic effector cells. Adrenergic receptors respond to the binding of norepinephrine (NE), which may have an excitatory or inhibitory effect.
How do cholinergic and adrenergic receptors differ Where do we generally find each type of receptor in the sympathetic nervous system?
In the sympathetic nervous system, you will find cholinergic receptors on all postganglionic neurons and the adrenal medulla. You will find adrenergic receptors on all targets of the sympathetic nervous system (thoracolumbar division).

Adrenergic receptors are cell surface glycoproteins that recognize and selectively bind the catecholamines, norepinephrine and epinephrine, which are released from sympathetic nerve endings and the adrenal medulla.
Are cholinergic receptors sympathetic or parasympathetic?
The term cholinergic refers to those receptors which respond to the transmitter acetylcholine and are mostly parasympathetic.

What are the two branches of the autonomic nervous system?
Like the autonomic nervous system (ANS), the division responsible for automatic responses like the beating of the heart and other organ functions involving smooth muscles, this system is further regulated by two specific branches called the adrenergic and cholinergic pathways . Each pathway has its own unique set of receptors and triggers to induce a certain action.
What neurotransmitter induces the fight and rest response?
Because of the action of these neurotransmitters, they will trigger different kinds of effects onto the body. Generally, the PNS or cholinergic induces the ‘digest and rest’ effects while the SNS or adrenergic mimics the effect of the ‘fight or flight response’ as in the case when there is too much excitement. Inducing the digest and rest means that the gastrointestinal (GI) and genitourinary (GU) systems’ effects are increased (excited) while imitating the fight or flight response excites all other system effects except the GI and GU.
