Neurotransmitter substance released at motor end plates by the motor neuron?
acetylcholne
Is curare poisoning affected by the motor end plate or the axon terminal?
myasthenia gravis is affected by the motor end plate .it is a autoimmune disorder caused by the formation of circulating antibodies to the nicotinic A-ch receptors present in motor end plate.
How does a neuromuscular blocking agent such as metubine interfere with muscle contraction?
A Neuromuscular block may use metubine. Metubine will cause the receptors on the motor end- plate to bind. It antagonizes the neurotransmitter actions when it causes it to bind.
What happens to the muscle membrane when acetylcholine binds to receptors at the motor plate?
When acetylcholine binds to receptors at the motor plate, this binding opens ligand-gated ion channels on the motor end plate, ions diffuse through the open ligand gated ion channels, and the flow of ions causes the motor end plate to reach threshold and an action potential is generated at the motor end plate.
What neurotransmitter is released at the motor end plates by axon terminals?
The accepted terminology is either neurotransmitter or neuromodulator. The compounds are epinephrine, ACh, norepiniphrine, GABA, glycine, ATP , ADP, adenosine, glutamate, aspartate, substance P, Neuropeptide Y, LHRH and probably 2 dozen others. In addition NO (nitric oxide) acts as a neuronal released modulator (albeit not by synaptic release).
Neurotransmitter substance released at motor end plates by the motor neuron?
acetylcholne
Which neurotransmitter receptor is present on the sarcolemma?
End of the muscle fiber I think it is the motor end plate
Binding of neurotransmitter to the receptors on the motor endplate open?
Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate. Further down the line, this would cause muscle contraction through the release of Ca2+ from the SR.
What is the name of the neurotransmitter that produces an end plate potential?
Acetylcholine
What is the name of the point at which motor neuron synapses motor end plate?
cappilaries is the name of the point at which motor neuron synases motor end plate
What type of ion channel opening is caused by the binding of neurotransmitters to the receptors on the motor endplate?
Sodium enters the cell and causes depolarization. A small amount of potassium also leaves the motor end plate. This means binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate.calcium
Contraction mechanism in a skeletal muscle cell?
ACH is released at the end-plate potential. ACH diffuses into the sarcolemma, attaches to the receptors in the motor end plate and causes a change in the ions permeability that creates graded depolarization of the end-plate potential. Basically, it attaches to the receptors in the motor-end plate and creates the beginning process of triggering muscle contractions.

How does a motor neuron form a synapse with a muscle cell?
motor end plate
What part of nervous system transmit message?
Impulses in the cell body (soma) of a neuron and move on along its axon, which conducts the impulse to a synapse at the end of the axon. There neurotransmitters are released into the synaptic cleft, so that the impulse can stop or go on to the next neuron or a gland/motor end plate, depending on the kind of neurotransmitter. Different types of neurotransmitters are: acetylcholine, adrenaline, noradrenaline, serotonine.
