Like any other neurotransmitter, acetylcholine will attach itself to active sites on the dendrite, thus triggering the opening of sodium gates of the next neuron. Once that's done, the acetylcholine either breaks down or is absorbed back into the cell it originated from.

When acetylcholine diffuses across the synaptic cleft and binds to receptors on the folded sarcolemma it initaly causes what channels to open in the sarcolemma?
Chemically gated Na+ ions.
The signal to excite a muscle cell must cross the neuromuscular junction by the diffusion of acetylcholine across the?
synaptic cleft
How is acetylcholine (ACh) removed from the synaptic cleft?
Acetylcholine is degraded by acetylcholinesterase
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.
What neurotransmitter does not go through the re-uptake process?
Acetylcholine is a neurotransmitter that does not go through the reuptake process. Instead, it is broken down by an enzyme called acetylcholinesterase in the synaptic cleft.

What is the substance released into the synaptic cleft?
acetylcholine
What is the normal sequence of events that occur during synaptic transmission at a motor end plate?
1. Nerve impulse reaches synaptic terminal. 2. Synaptic vesicles move to and merge with the presynaptic cell membrane of the motor neuron. 3. Acetylcholine is released into and diffuses across the synaptic cleft. 4. Acetylcholine binds to receptors on the postsynaptic cell membrane of the muscle fiber.
How is acetylcholine (ACh) removed from the synaptic cleft?
Acetylcholine is degraded by acetylcholinesterase
What are the names of some common neurotransmitters?
Acetylcholine or aka ACH is the neurotransmitter that is released from the axon terminal to through the neuromuscular junction across the synaptic cleft which binds to the ACH receptors on the end motor plate of the Sarcolema.
What is the ion needed to initiate the release of acetylcholine into the synaptic cleft called?
calcium - Ca2+
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.
What neurotransmitter does not go through the re-uptake process?
Acetylcholine is a neurotransmitter that does not go through the reuptake process. Instead, it is broken down by an enzyme called acetylcholinesterase in the synaptic cleft.
What most directly causes synaptic vesicles to release acetylcholine into the synaptic cleft?
calcium entering the axon terminal
What does acetylcholinerase do?
Also known as AChE, Acetylcholinesterase is an enzyme that breaks down the neurotransmitter acetylcholine, resulting in choline and an acetate group. This occurs at the synaptic cleft. Too much acetylcholine can lead to paralysis
Acetylcholine in the synaptic cleft is broken down by?
choline esterase enzyme and there is 2 types of choline esterase 1 .truecholine esterase 2. pseudo choline esterase
