a small organic molecule liberated at nerve endings as a neurotransmitter
. It is particularly important in the stimulation of muscle tissue. The transmission of an impulse to the end of the nerve causes it to release neurotransmitter molecules onto the surface of the next cell, stimulating it. After such release, the acetylcholine is quickly broken into acetate and choline, which pass back to the first cell to be recycled into acetylcholine again. The poison curare
acts by blocking the transmission of acetylcholine. Some nerve gases operate by preventing the breakdown of acetylcholine causing continual stimulation of the receptor cells, which leads to intense spasms of the muscles, including the heart. Acetylcholine is often abbreviated as Ach.
What else can I help you with?
Neurotransmitter acetylcholine has a major role in what behavioral function?
Acetylcholine plays a major role in muscle movement, memory formation, and cognitive functions in the nervous system. It is also involved in the regulation of attention, learning, and overall brain function.
What are the two excitatory neurotransmitters?
acetylcholine
What is an antiacetylcholinesterase?
It is an enzyme that catalyzes the breakdown of acetylcholine and of some other choline esters that function as neurotransmitters.
What do Acetylcholine receptors function as?
Acetylcholine receptors function as neurotransmitter receptors that respond to the neurotransmitter acetylcholine (ACh). They are primarily found in the neuromuscular junction and in the central and peripheral nervous systems. These receptors can be categorized into two main types: nicotinic receptors, which are ionotropic and mediate fast synaptic transmission, and muscarinic receptors, which are metabotropic and are involved in slower, modulatory signaling pathways. Their activation plays a crucial role in muscle contraction, autonomic functions, and cognitive processes.
What are little sacs that carry out molecules?
Little sacs that carry out molecules are called vesicles. They are involved in various cellular processes such as transporting molecules within the cell, releasing substances outside the cell, and maintaining cell structure and function.
What is the function of air sacs?
The function of air sacs (alveoli) is to provide a large surface area for gas exchange
Which is not a function of air sacs?
c plato ppl
What is the function of air sacs in aquatic animals?
The air sacs in aquatic animals are used to get okygen bubbles out of water.
How does Aricept work?
One of the main problems in Alzheimers disease is a decrease in acetylcholine, a neurotransmittor. Aricept blocks an enzyme called acetylcholine esterase from breaking down acetylcholine so that the available neurotransmittor can work for a longer period of time.
Closely stacked flattened membrane sacs structure or function?

Neurotransmitter acetylcholine has a major role in what behavioral function?
Acetylcholine plays a major role in muscle movement, memory formation, and cognitive functions in the nervous system. It is also involved in the regulation of attention, learning, and overall brain function.
What is the function of the air?
Multiple air sacs connect to lungs. By Milo Magallanes.
What is acetylcholinesterace?
Acetylcholinesterase, also known as AChE, is an enzyme which is critical to the function of animals from ants to elephants. This enzyme's sole responsibility is to break down the neurotransmitter acetylcholine. Acetylcholine sends messages between nerves, signaling muscle contractions. If the neurotransmitter was not broken down after it had served its function, the muscle involved would not be able to relax, and this could create spasms, paralysis, and other problems.
What do Cholinergic fibers secrete?
Cholinergic fibers secrete acetylcholine, which is a neurotransmitter responsible for transmitting signals in the nervous system. Acetylcholine plays a role in various physiological processes, including muscle movement, regulation of heart rate, and memory function.
What is an example of acetylcholine?
acetylcholine
What is the main neurotransmitter of the parasympathetic autonomic nervous system?
Parasympathetic system has acetylcholine as its chemical mediator.
What is the structure and function of the lungs?
It has many balloon-like sacs that can hold air.
