What else can I help you with?
What is the main neurotransmitter of the parasympathetic autonomic nervous system?
Parasympathetic system has acetylcholine as its chemical mediator.
What drugs increase the action of the nervous system?
acetylcholine
What is the neurotransmitter in the brain spinal cord and peripheral nervous system?
Acetylcholine
Which part of the autonomic system decreases pulse rate?
The parasympathetic nervous system, part of the autonomic nervous system, decreases pulse rate. It is sometimes referred to as the rest and digest system.
Neurotransmitter used to cause muscle contraction?
A neurotransmitter that causes muscle movement is called Acetylcholine. Acetycholine acts as on both the central nervous system and the peripheral nervous system.
All preganglionic axons of the autonomic nervous system release what?
acetylcholine (ACH)
Is acetylcholine the only neurotransmitter in motor division of somatic nervous system?
yes
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 is acetylcholen?
Acetylcholine (ACh) is an exitatory neurotransmitter. This means it is released from the synapse of the neurone and promotes the continuation of the AP in the next neurone instead of inhibiting it. ACh is part of the peripheral nervous system and is not very prominent in the central nervous system.
What part of the nervous system is the sympathetic and parasympathetic?
No. While they are both composed of neurons and support cells, they are classified under different branches of the nervous system. The brain is a part of the central nervous system, while the autonomic nervous system is part of the peripheral nervous system.
What substance is released by the nervous system and excites muscle cells?
Acetylcholine is the neurotransmitter released by the nervous system that excites muscle cells, leading to muscle contraction.
What neurotransmitter is part of the PNS?
The chemical most commonly found in both pre- and postganglionic synapses in the parasympathetic system is the neurotransmitter acetylcholine.
