it acts as just a neurotransmitter for both the central nervous system and the peripheral nervous system

Acetylcholine functions as both a neurotransmitter in the nervous system, where it is involved in transmitting signals between nerve cells, and as a neuromodulator that influences the activity of other neurotransmitter systems. It plays a critical role in muscle contraction and movement, as well as in memory, learning, and attention.

What are the two excitatory neurotransmitters?
acetylcholine
What susbstance is found in synaptic vesicles of axon terminal?
Neurotransmitters are the substances found in synaptic vesicles of axon terminals. These neurotransmitters are released into the synapse, where they transmit signals from one neuron to another. Some common neurotransmitters include dopamine, serotonin, and acetylcholine.
What are the two neurotransmitters that axon terminals of autonomic neurons release?
The two main neurotransmitters released by the axon terminals of autonomic neurons are acetylcholine and norepinephrine. Acetylcholine is predominantly released by parasympathetic neurons, while norepinephrine is released by sympathetic neurons.
How are neurotransmitters degraded?
A neurotransmitter is either taken up by the presynaptic terminus or digested/cleaved in the synaptic cleft. For example Acetylcholine is cleaved by a specific esterase present in the neuromuscular junction.
What two functions do acetylcholine perform?
Along with dopamine, serotonin and norepinephrine, acetylcholine is a neural transmitter. Some substances act as mediators and others, including acetylcholine, simulate or active the next nerve cell as impulses pass down the a nerve. Once it has performed this action by passing across the synapse (neural junction between two nerve cells) it is broken down by an enzyme called acetylcholine esterase into an acetyl group and choline. Acetylcholine also passes across the neural muscular junction, similar to the synapse between neurons (nerve cells) and also between nerve endings and muscle cells stimulating them and thus causing your muscles to move. Acetylcholine is also involved in memory and learning and is in particularly short supply in people with Alzheimer's disease. A recently released drug helps Alzheimers sufferers by inhibiting the action of acetylcholine esterase.

The two neurotransmitters that affect smooth muscle cells are acetylcholine and?
norepinephrine. Acetylcholine mainly causes smooth muscle contraction, while norepinephrine can either cause contraction or relaxation depending on the type of receptor it binds to on the smooth muscle cell.
What are the two neurotransmitters that axon terminals of autonomic neurons release?
The two main neurotransmitters released by the axon terminals of autonomic neurons are acetylcholine and norepinephrine. Acetylcholine is predominantly released by parasympathetic neurons, while norepinephrine is released by sympathetic neurons.
What Two major neurotransmitters are involved in regulating physiological responses to exercise?
Acetylcholine and norepinephrine.
Two major neurotransmitters of the autonomic nervous system?
You have acetylcholine liberated at ganglion in both sympathetic and parasympathetic nervous system. You have noradrenaline secreted at post ganglionic sympathetic nerve terminals. You have acetylcholine secreted at post ganglionic parasympathetic nerve terminals.
What two functions does an antenna performs?
An antenna functions to receive electromagnetic signals from a transmitter and convert them into electrical signals for a device to process. It also transmits electrical signals from a device into electromagnetic signals to be sent to a receiver.
What type of chemicals moves across the space between two nerve cells?
chemical synapse
The two types of receptors that bind acetylcholine are?
nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotinemuscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.Nicotinic and muscarinic are two main kinds of "cholinergic" receptors.
What crosses a synapse?
Neurotransmitters are the chemicals that cross a synapse to transmit signals between neurons. These neurotransmitters are released by the presynaptic neuron and received by the postsynaptic neuron to relay information in the nervous system.
How are neurotransmitters degraded?
A neurotransmitter is either taken up by the presynaptic terminus or digested/cleaved in the synaptic cleft. For example Acetylcholine is cleaved by a specific esterase present in the neuromuscular junction.
