What position on the muscle cell where the nerve fibers connect?
The point where a nerve fiber connects to a muscle cell is known as the neuromuscular junction. This connection allows the nerve signal, or action potential, to be transmitted from the nerve to the muscle cell, triggering muscle contraction.
Is depolarization in the heart passed cell to cell in the same way they are the neuromuscular junction?
No, depolarization in the heart is not passed cell to cell in the same way as at the neuromuscular junction. In the heart, gap junctions allow for direct electrical coupling between adjacent cardiac muscle cells, allowing the depolarization signal to quickly spread from cell to cell. In the neuromuscular junction, depolarization is transmitted by the release of neurotransmitters across the synaptic cleft from a neuron to a muscle cell.
What site where the motor neuron and muscle cell meet is called the?
The site where a motor neuron and muscle cell meet is called the neuromuscular junction. This is where the motor neuron releases neurotransmitters that signal the muscle cell to contract.
The chemical that transmits the signal across the neuromuscular junction is called?
Acetylcholine is the chemical that transmits signals across the neuromuscular junction. It binds to receptors on the muscle cell membrane, leading to muscle contraction.
In the synaptic cleft of a neuromuscular junction what enzyme is always present?
Acetylcholinesterase is always present in the synaptic cleft of a neuromuscular junction. It is responsible for breaking down the neurotransmitter acetylcholine, allowing for the termination of the signal transmission between the neuron and the muscle cell.
What position on the muscle cell where the nerve fibers connect?
The point where a nerve fiber connects to a muscle cell is known as the neuromuscular junction. This connection allows the nerve signal, or action potential, to be transmitted from the nerve to the muscle cell, triggering muscle contraction.
Which part of the nerve cell ivides into synaptic end-bulbs at neuromuscular junction?
The axon.
The axon terminals of a nerve cell and the sarcolemma of a skeletal muscle cell join at the?
The axon terminals of a nerve cell and the sarcolemma of a skeletal muscle cell join at the neuromuscular junction. This is where the nerve impulse triggers the release of neurotransmitters, such as acetylcholine, which initiate muscle contraction by binding to receptors on the sarcolemma.
Is depolarization in the heart passed cell to cell in the same way they are the neuromuscular junction?
No, depolarization in the heart is not passed cell to cell in the same way as at the neuromuscular junction. In the heart, gap junctions allow for direct electrical coupling between adjacent cardiac muscle cells, allowing the depolarization signal to quickly spread from cell to cell. In the neuromuscular junction, depolarization is transmitted by the release of neurotransmitters across the synaptic cleft from a neuron to a muscle cell.
The junction between a motor neurons axon and the muscle cell membrane is called a neuromuscular junction or a?
The junction between a motor neruon's axon and the muscle cell membrane is called a neuromuscular junction or a myoneuraljunction?
What prevents ACh from accummulating in the neromuscular junction?
Acetylcholinesterase is an enzyme that breaks down acetylcholine into choline and acetate at the neuromuscular junction. This prevents acetylcholine from accumulating and allows for efficient signaling between the nerve cell and the muscle cell.
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.
Type of junction where a motor neuron and a skeleton muscle cell have contact?
Neuromuscular junction. It is the point of contact between the motor neuron and the skeletal muscle cell, where the motor neuron releases neurotransmitters that trigger muscle contraction.
What site where the motor neuron and muscle cell meet is called the?
The site where a motor neuron and muscle cell meet is called the neuromuscular junction. This is where the motor neuron releases neurotransmitters that signal the muscle cell to contract.
The actual gap between an axon ending and the muscle cell is called what?
Neuromuscular junction.
The junction between a motor neurons axon and the muscle cell membrane is called?
neuromuscular junction or myoneural junction
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.
