How does the neural signal get across the neuromuscular junction?
a neurotransmitter chemical crosses the junction.
Is depolarization in the heart passed cell to cell in the same way they are the neuromuscular junction?
false
What does ach do at a neuromuscular junction?
ACh (acetylcholine) binds to receptors at the NMJ (neuromuscular junction) to induce contraction of muscle.
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.
A folded region of the sarcolemma at the neuromuscular junction?
At the neuromuscular junction (or presynaptic end) of the sarcolemma, it is referred to as end plate synapse potential.
Which neurotransmitter is released at the neuromuscular junction?
ACETYLCHOLINE
Into what does the neuron release its neurotransmitter at the neuromuscular junction?
cytoplam
How does the neural signal get across the neuromuscular junction?
a neurotransmitter chemical crosses the junction.
What neurotransmitter is released at the neuromuscular junction?
acetylecholine
Is depolarization in the heart passed cell to cell in the same way they are the neuromuscular junction?
false
What is the point of contact between a motor neuron and a skeletal muscle cell called?
This point is often called the neuromuscular junction or motor end plate. ?The neurotransmitter used here is acetylcholine.Many diseases occur with dysfunction at this junction, like Myesthenia Gravis, botulism, or Lambert Eaton Myasthenic Syndrome.
What systems do nerve agents affect?
Nerve agents typically affect the acetylcholine system by irreversibly binding to the enzyme, acetylcholinesterase. This prevents the body from catabolizing acetylcholine, resulting in an accumulation of the neurotransmitter in the synapse and neuromuscular junction.
How do bones and muscles work to have movement?
The neuromuscular junction. A chemical called neurotransmitter is released from a neuron to stimulate the muscle fibers to contract.
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 is the site where the muscle fiber and nerve fiber meet called?
Well of course they meet at the neuromuscular junction
What does ach do at a neuromuscular junction?
ACh (acetylcholine) binds to receptors at the NMJ (neuromuscular junction) to induce contraction of muscle.
Movement of arms and legs what major neurotransmitter involved?
Skeletal muscles move via action potential that is conducted by axons to the neuromuscular junction and across the synaptic gaps of efferent motor neurons. The main neurotransmitter responsible for this job is acetylcholine.
