It is a neurotransmitter at cholinergic synapses in the central, sympathetic and parasympathetic nervous systems. Abbreviated ACh.acetylcholine receptorsstructures located at the endorgans, e.g. at the skeletal muscle fibers. The myofibers are stimulated to contract by the interaction of acetylcholine with acetylcholine receptors which are located on the motor end plate or postsynaptic sarcolemma.
Acetylcholine receptors are gated ion channels that open in response to acetylcholine, leading to an increase in membrane conductance.

What enzyme has to be present for acetylcholine to be broken down so that the muscle fiber can relax?
Acetycholine esterase. It breaks down Ach in the skeletal muscle endplate.
How do motor neurons receive instructions from adjacent neurons?
These instructions are received in the form of an impulse stimulation of a particular protein channel on the dendrite by a neurotransmitter termed acetycholine (ACh).
What causes the rapid change in the resting membranes potential that initiates an action potential?
In muscle cells the inward current is a sodium + calcium flow through acetycholine activated channels as well as through voltage sensitive calcium channels.
What is the chemical transmitter released at the neuromuscular junction?
The neurotransmitter acetylcholine is released into the synaptic cleft to bind with receptors on muscle cells. Upon binding, the muscle cells contract.
How was ice found?
it was found by people it was found by people
Where are acetycholine receptors found?
In the Sarcolemma
Where is acetycholine broken down into acetate and choline?
Acetycholine is broken down into acetate and choline in the synaptic cleft.
Give an example of chemical same like serotonin?
acetycholine
When is acetycholine released?
acetylcholine is released from presynaptic neurons in response to a nerve impulse
Where does acetycholine come from?
acetyl choline is a neuro transmitter it will come from the brai. it comes from the vagus nerve
Nicotine facilitates the release of a neurotransmitter which causes an individual to feel more alert This neurotransmitter is known as?
acetycholine
What is the most common neurotransmitter in the human body?
GABA (gamma-aminobutyric acid
The venom of the black widow spider causes violent muscle contractions by flooding synapses with?
It floods the synapses with Acetycholine or ACh.
What neurotransmitter is found at the synapse between nerves and human skeletal muscle cells?
Acetylcholine is the neurotransmitter at the neuromuscular junction.
What enzyme has to be present for acetylcholine to be broken down so that the muscle fiber can relax?
Acetycholine esterase. It breaks down Ach in the skeletal muscle endplate.
How do motor neurons receive instructions from adjacent neurons?
These instructions are received in the form of an impulse stimulation of a particular protein channel on the dendrite by a neurotransmitter termed acetycholine (ACh).
What does acetycholine do to muscles?
Acetylcholine acts to excite skeletal muscles, allowing for the muscle to contract. It also serves to allow contractions in the smooth muscles, while slowing down the cardiac muscles
