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.

Which neurotransmitter receptor is present on the sarcolemma?
End of the muscle fiber I think it is the motor end plate
What is the neurotransmitter of the motor neuron?
Alpha-Motor neurons release the neurotransmitter acetylcholine at a synapse called the neuromuscular junction. When the acetylcholine binds to acetylcholine receptors on the muscle fiber, an action potential is propagated along the muscle fiber in both directions.
Opening of these channels leads to what of the motor endplate?
Depolarization
What is the neurotransmitter in a somatic motor pathway?
Acetylcholine
Receptors for acetylcholine are located on the?
Acetylcholine receptors are located on the motor end plate or postsynaptic sarcolemma. Otto Loewi was a German pharmacologist whose discovery of acetylcholine earned the 1936 Nobel prize in Physiology or Medicine which he shared with Sir Henry Dale. Acetylcholine is a neurotransmitter. Neurotransmitters are chemicals that transmit signals from a neuron to a target cell across the synapse and most are synthesized at the nerve terminals.
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 another site within the neuromuscular junction that might be affected to prevent muscle contraction?
The motor endplate is the is the large, complex terminal formation by which a motor neuron axon establishes synaptic contact with a striated muscle fiber. While succinylcholine produces motor endplate depolarization at the neuromuscular junction to prevent acetylcholine release, curare and medical derivatives such as tubocurarine are non-depolarizing neuromuscular blocking agents that inhibit depolarization by blocking acetylcholine from binding to receptors on the motor endplate (i.e., the curare site of action is the nicotinic acetylcholine receptors on the postsynaptic membrane of the neuromuscular junction). Curare occupies the agonist position in competition against acetylcholine.
What neurotransmitter control the somatic nervous system and how does it work?
Acetylcholine (ACh) is the only neurotransmitter used in the motor division of the somatic nervous system. It works by binding to acetylcholine receptors on skeletal muscle fibers and opening ligand-gated sodium channels in the cell membrane.
What neurotransmitter controls the somatic nervous system how does it work?
Acetylcholine (ACh) is the only neurotransmitter used in the motor division of the somatic nervous system. It works by binding to acetylcholine receptors on skeletal muscle fibers and opening ligand-gated sodium channels in the cell membrane.

What receptors are present in frog's rectus abdominus muscle?
Nicotinic receptors are commonly present in the neuromuscular junction (neuromuscular endplate). They respond to acetylcholine released from the terminals of motor neurons by opening to allow deploarizing K+ flow.
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 is the neurotransmitter of the motor neuron?
Alpha-Motor neurons release the neurotransmitter acetylcholine at a synapse called the neuromuscular junction. When the acetylcholine binds to acetylcholine receptors on the muscle fiber, an action potential is propagated along the muscle fiber in both directions.
What is the neurotransmitter of alpha-motor neuron?
Alpha-Motor neurons release the neurotransmitter acetylcholine at a synapse called the neuromuscular junction. When the acetylcholine binds to acetylcholine receptors on the muscle fiber, an action potential is propagated along the muscle fiber in both directions.
Opening of these channels leads to what of the motor endplate?
Depolarization
What is the function of motor end plate?
A motor endplate is a large special synaptic contact between motor axons and each skeletal muscle fiber. Each muscle fiber forms one endplate. Its function is to transmit impulses from nerves to muscles.
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.
