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 else can I help you with?
Into what does the neuron release its neurotransmitter at the neuromuscular junction?
The neuron releases its neurotransmitter into the synaptic cleft at the neuromuscular junction, which is the gap between the neuron terminal and the muscle cell. This neurotransmitter then binds to receptors on the muscle cell membrane, triggering muscle contraction.
What is presynaptic inhibition and how does it regulate neurotransmitter release in the nervous system?
Presynaptic inhibition is a process in which the release of neurotransmitters from a neuron is reduced by another neuron. This regulation occurs when the inhibitory neuron releases a neurotransmitter that decreases the excitability of the presynaptic neuron, leading to a decrease in neurotransmitter release. This mechanism helps to fine-tune communication between neurons and maintain balance in the nervous system.
What is the name of the tiny gap the neurotransmitter has to diffuse across to reach the membrane of the postsynaptic neuron?
The tiny gap that the neurotransmitter has to diffuse across to reach the membrane of the postsynaptic neuron is called the synaptic cleft. It separates the axon terminal of the presynaptic neuron from the dendrite of the postsynaptic neuron.
What is a motor neuron attached to?
A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.
How Neurotransmitter molecules are removed from a synapse by?
Neurotransmitter molecules are removed from a synapse through a process called reuptake or enzymatic degradation. In reuptake, the neurotransmitter is taken back up into the presynaptic neuron. In enzymatic degradation, special enzymes break down the neurotransmitter molecules into inactive byproducts.
In a neuromuscular junction synaptic vesicles in the motor neuron contain which neurotransmitter In a neuromuscular junction synaptic vesicles in the motor neuron contain which neurotransmitter?
In a neuromuscular junction, synaptic vesicles in the motor neuron contain the neurotransmitter acetylcholine (ACh). When an action potential reaches the motor neuron, ACh is released into the synaptic cleft and binds to receptors on the muscle fiber, leading to muscle contraction.
What does axon terminal of motor neuron release?
The axon terminal of a motor neuron releases the neurotransmitter acetylcholine. Acetylcholine is responsible for transmitting signals from the motor neuron to muscle fibers, leading to muscle contractions.
What neurotransmitter neuron to muscle cell?
The neurotransmitter acetylcholine is released from neuron axon terminals and binds to nicotinic receptors on muscle cells, triggering muscle contraction.
Transferring messages from a motor neuron to a leg muscle requires the neurotransmitter known as?
acetylcholine
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 kind of stimulus (electrical or chemical) travels from the motor neuron to skeletal muscle?
This is done through a neurotransmitter. So the answer is chemical.
Into what does the neuron release its neurotransmitter at the neuromuscular junction?
The neuron releases its neurotransmitter into the synaptic cleft at the neuromuscular junction, which is the gap between the neuron terminal and the muscle cell. This neurotransmitter then binds to receptors on the muscle cell membrane, triggering muscle contraction.
What is the neurotransmitter used at the neuro muscular junction is?
The neurotransmitter used at the neuromuscular junction is acetylcholine. It is released from the motor neuron terminals and binds to receptors on the muscle cell membrane, leading to muscle contraction.
What neurotransmitter does the adrenergic neuron produce?
Norephinephrine
Which motor neuron is in charge of muscle contraction?
The motor neuron responsible for muscle contraction is the alpha motor neuron. These neurons reside in the spinal cord and project to skeletal muscles, where they release the neurotransmitter acetylcholine at the neuromuscular junction. This release initiates muscle contraction by triggering action potentials in muscle fibers, leading to their shortening and generating movement.
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.
What neurotransmitter do first order neuron secrete?
ach
