What are the receptors called that are found on the end of the motor end plate?
The receptors found on the end of the motor end plate are called nicotinic acetylcholine receptors. These receptors respond to the neurotransmitter acetylcholine released from the motor neuron and play a crucial role in initiating muscle contraction.
Neurotransmitter substance released at motor end plates by the motor neuron?
The neurotransmitter released at motor end plates by motor neurons is acetylcholine. It binds to receptors on the muscle cell membrane, leading to muscle contraction.
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).
What effect does depolarization have on the motor end plate once action potentials arrive at the synaptic end bulb?
Depolarization at the motor end plate upon arrival of action potentials triggers the release of neurotransmitter acetylcholine into the synaptic cleft. This acetylcholine then binds to receptors on the muscle cell membrane, initiating muscle contraction by depolarizing the muscle cell membrane and allowing the action potential to propagate along the muscle fiber.
Is curare poisoning affected by the motor end plate or the axon terminal?
Curare poisoning affects the motor end plate. Curare blocks nicotinic acetylcholine receptors on muscle cells at the neuromuscular junction, preventing the binding of acetylcholine and leading to muscle paralysis.

What is the name of the neurotransmitter that produces an end plate potential?
Acetylcholine
Binding of neurotransmitter to the receptors on the motor endplate open?
When a neurotransmitter binds to its receptor on the motor endplate, it triggers the opening of ion channels in the postsynaptic membrane. This allows for the influx of ions, typically leading to depolarization of the muscle cell membrane and initiation of a muscle action potential. Subsequently, this leads to contraction of the muscle fiber.

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
What is the name of the point at which motor neuron synapses motor end plate?
The point at which a motor neuron synapses with a muscle fiber's motor end plate is called the neuromuscular junction. This is where the nerve impulse is transmitted from the motor neuron to the muscle fiber, leading to muscle contraction.
What effect does depolarization have on the motor end plate once action potentials arrive at the synaptic end bulb?
Depolarization at the motor end plate upon arrival of action potentials triggers the release of neurotransmitter acetylcholine into the synaptic cleft. This acetylcholine then binds to receptors on the muscle cell membrane, initiating muscle contraction by depolarizing the muscle cell membrane and allowing the action potential to propagate along the muscle fiber.
What causes an action potential when it binds the motor end plate?
When the neurotransmitter acetylcholine binds to the motor end plate, it triggers the opening of sodium channels in the muscle cell membrane. This influx of sodium ions leads to depolarization of the cell, creating an action potential that propagates along the muscle fiber, ultimately leading to muscle contraction.
How does a motor neuron form a synapse with a muscle cell?
motor end plate
Is curare poisoning affected by the motor end plate or the axon terminal?
Curare poisoning affects the motor end plate. Curare blocks nicotinic acetylcholine receptors on muscle cells at the neuromuscular junction, preventing the binding of acetylcholine and leading to muscle paralysis.
Which neurotransmitter receptor is present on the sarcolemma?
Acetylcholine receptor is present on the sarcolemma of the muscle cells. This receptor is responsible for transmitting the signal to initiate muscle contraction when acetylcholine binds to it at the neuromuscular junction.
